Yes you can - purchase a 12 Volt DC to 110 Volt AC converter (you can get at Staples or Home Depot). This will allow you to plug your adapter into the converter while it's plugged into the cigarette lighter jack in the car.

What is causing the battery to drain?


Running the car will drain the battery it if it's not charging ! An if your charging light is on it isn't charging ! Did you check power an grounds on the alternator ? There is a single heavier wire on the back of the alternator, this should have battery voltage ! You may want to take this to a ASE certified repair shop !
Functionality
With the ignition switch in the RUN position, voltage is applied through the warning indicator I circuit 904 (LG/RD) to the voltage regulator. This turns the regulator on, allowing current to flow from battery sense A circuit 35 (OG/LB) to the generator field coil. When the engine is started, the generator begins to generate alternating current (AC) which is internally converted to direct current (DC). This current is then supplied to the vehicle's electrical system through the output (B+) terminal of the generator.
Once the generator begins generating current, a voltage signal is taken from the generator stator and fed back to the regulator S circuit 4 (WH/BK). This voltage feedback signal (typically half the battery voltage) is used to turn off the warning indicator.
With the system functioning normally, the generator output current is determined by the voltage of the A circuit 35 (OG/LB). The A circuit 35 (OG/LB) voltage is compared to a set voltage internal to the regulator, and the regulator controls the generator field current to maintain the correct generator output.
The set voltage will vary with temperature and is typically higher in cold temperatures and lower in warm temperatures. This allows for better battery recharge in the winter and reduces the chance of overcharging in the summer.
Battery Positive Output (B+) Circuit 38 (BK/OG)
The generator output is supplied through the battery positive output (B+) terminal on the back of the generator to the battery and electrical system.
I Circuit 904 (LG/RD)
The I (ignition) circuit 904 (LG/RD) is used to turn on the voltage regulator. This circuit is powered up with the ignition switch in the RUN position. This circuit is also used to turn the charging system warning indicator on if there is a fault in the charging system operation.
A Circuit 35 (OG/LB)
The A (battery sense) circuit 35 (OG/LB) is used to sense battery voltage. This voltage is used by the regulator to determine generator output. This circuit is used to supply current to the generator field (rotor). The amount of current supplied to the rotor will determine generator output.
S Circuit 4 (WH/BK)
The S (stator) circuit 4 (WH/BK) is used to feed back a voltage signal from the generator to the regulator. This voltage is used by the regulator to turn off the charging system warning indicator. The S circuit is fed back externally on external mounted regulator generators.

Outlets not working all fuses are good

VOLT
AC
SYSTEM
The following electrical components (if so equipped) will only operate when your
RV is connected to shore power: 120 to
12-volt power converter, air conditioner,
120-volt refrigerator, microwave oven, television(s), fireplace and appliances
plugged into convenience receptacles.

SECTION 6 - ELECTRICAL SYSTEM JAYCO TOWABLE

120-
VOLT
CIRCUIT
BREAKERS
The 120-volt AC circuit breakers located in
side the main load center protect all
120-volt wiring and components in the RV fr
om circuit overloads and short circuits.
Should a circuit overload or short circui
t occur the circuit breaker protecting the
affected circuit will "trip" preventing the flow of electricity through that circuit.
If a circuit breaker trips, shut "off"
the appliance on that circuit (i.e., power
converter etc.) and allow the circuit breaker to cool down for a brief period of time.
After the cooling down period, reset the circuit breaker by moving its lever "off" and
then back to the "on" position. If the circuit breaker re-trips or frequently trips,
contact your dealer to have the electrical problem diagnosed and repaired.
A circuit breaker identification label is permanently attached to the inside surface
of the 120-volt load center.
Maintenance and Replacement
At the beginning of camping season, inspect the circuit breakers and replace as
needed. Test by turning each circuit breaker "off" and back "on". Circuit breakers
are wearable parts and must be replaced
as needed, as part of your RV
maintenance. If you have any questions, consult your dealer.
Please contact your dealer for repair assistance when replacing circuit breakers.
CONVERTER
The power converter converts 120-volt AC power to useable 12-volt DC power
when the shore power cord is connected to an external power source.
The converter has a built-in protective thermal breaker that will shut it down should
overheating occur. Overheating can be
caused by operating the converter above
its maximum power output for an extended period of time, or by an obstruction to
its ventilation air flow. To reduce converter heat build keep unnecessary 12-volt
lights and motors turned "off"
.
Keep the converter cooling fins and fan clear of
obstructions.
Inspection and maintenance
If the 12-volt power converter is not working (auxiliary battery not being charged)
check the reverse polarity fuse(s) in the converter fuse panel.
There are no
customer serviceable parts inside the converter case and the
manufacturer's warranty will be void if
the case has been removed
. If you
have further concerns contact your dealer.

Do I have a negative battery system or positive battery system?


If you have a 12volt standard electrical system in your vehicle.
It is both positive and negative. The travel inverter converts this 12 volt DC current into 110v 60hz AC current so you can plug in your electronics that require standard household current to charge/operate.
There is a built in USB port if you device will accept this for 12 volt power. It also has the power oultet with ground for 110v 6hz power.
Link below has a good picture and description. Hope this helps!

Will a 12 volt slide battery work in my 9.6 volt Black & Decker Firestorm drill. The 9.6 volt batteries don't seem to be made any more. I don't think I paid a lot more for the original drill...


This close to father's day you should be able to buy a new drill for about the same as a battery. The 12v would overheat the motor if you ran it for an extended period.

I have a 2001 flhtcui what are the ac reading coming from stator at 2.5k rpm 3k rpm and 3600 rpm. At 2000 rpm I get about 12 volts dash guage reading but at 3000 I get 13.5 to 14 at lower rpm 2000 or so I...


The AC output of the stator should be 32-40 volts at 2000 RPM (16-20 per 1000 RPM). With the battery fully charged, your regulator should supply between 13.5 and 15.0 DC volts to the battery. This should be the reading you get on your voltmeter. It will vary depending on what lights and other equipment you have turned on. Sounds like everything is working fine to me. The gauge is reading the DC voltage at the battery while the engine is running. At 2000 RPM, 12 volts is a little low but, considering the accuracy of the gauge, as long as it doesn't fall below 12 volts, it's about right. You don't ride for extended periods at engine RPMs that low. Then at 3000 RPM, 14 volts is about right. If your bike never ran anymore than 12 volts, your battery would slowly go down. If it goes any higher than 15.0 volts, it will boil the battery. Usually, about 14.3 or so with no load on the system is about right.

Good Luck

What do i need to stop my vehicles power source overpowering my head unit


Your vehicle's power source, (battery/Alternator), cannot "overpower" your head unit. A car's internal electrical system runs at 12 volts. Period. Your head unit requires 12 volts to operate.

The head unit will still work at 13-14 volts. If your cars electrical system was supplying more than 14 volts all your internal electrical devices would begin to fail.

You have some other problem.

Will not run only on gas but will not cool


If it works on gas and NOT electricity then the heating element is not getting power or the heating element is open. The heating element is located on the tubing just aft of where the pilot flame is on the bottom of the copper tube. You should check for power to the heating element and with power off perfom a continuity check on the element. I really do not at this time think you have a heating element problem.

There is a 120VAV element a AND a 12VDC element. The chances of both of these failing at the same time is pretty slim.

There is a note in the manual:
If the gas only pushbutton is depressed the
lamp will illuminate green and the refrigerator
will only operate on the LP gas mode, even if q
120 or 12 volts are available.

Another significant change in the third
generation A.E.S. system is how the 12 volt
heating element mode operates. As with the
first and second generation series, the 12 volt
heating element circuit is energized by the
ignition lock terminal. This terminal receives
its DC voltage from a wire that runs from the
run side of the vehicle’s ignition switch to the
refrigerator’s ignition lock terminal. This
allows the 12 volt heating element to be
energized only when the RV is traveling down
the road.
When the ignition lock terminal is energized
by the ignition key, the printed circuit board
must see at least 13.3 volts DC for a period of
40 seconds before the system will activate the
12 volt DC heating element.
If 13.3 volts is not achieved in this time frame,
the electronics will light the LP gas burner and
the refrigerator will operate on the LP gas
mode.
LOWER THAN 13.3 V.D.C. =LP Operation

If the battery voltage remains low after the
delay cycle, the automatic controls will light
the refrigerator on the LP gas mode and stay
on the gas mode until the printed circuit board
sees approximately 13.3 volts DC to the
terminal block.

For proper cooling on the AC mode, the AC
voltage to the refrigerator should not vary
more than 10 percent from the voltage rating
on the heating element. Heating elements used
in Dometic refrigerators could have a rated
voltage of 110 volts, 115 volts or 120 volts AC.
Because of this, the power requirements for
each differently rated heating element will
vary. For example, if a heating element is
rated for 100 volts, the acceptable power range
would be between 99 to 121 volts AC. If an
element is rated for 115 volts, the acceptable
power range would be between 103.5 to 126.5
volts AC. If the heater is rated for 120 volts,
the acceptable AC power range would be
between 108 to 132 volts AC.

The unit to operate on either AC or DC must have 13.3 volts to the unit. I think this is where your problem lies in that the battery voltage is less than 13.3 VDC


If all of that checks good just repsond here and I will help you. There is still more that can be checked.

Thanks for choosing FixYa.

Have a 92 aeorstar and code 12 in going off how do i find out what code 12 is


If you don't have a blown fuse code 12 indicates a drop in voltage from your battery charging system to below 9 volts. It is technically called "air bag deploy circuit drop in battery voltage" Before spending a bunch of money chasing this problem I would recommend the battery and alternator be tested, at most auto parts stores this is a free service.
Hope this was helpful.

How to use cruise control


Here are the steps in using cruise control:

  1. Get on a road you will be traveling at the same speed for a long period of time, such as a freeway.
  2. Reach your desired speed. Choose a speed that allows you to move with the flow of traffic and not go over or under the designated speed limit for that road.
  3. Locate the ON and SET buttons on your steering wheel. Press ON first and SET after. Your cruise control is now activated. Most vehicles must be traveling at least 30 miles per hour to set the cruise control.
  4. Press and hold the SET button if you wish to use cruise control at a higher speed. Hold until your desired speed is reached.
  5. Decrease speed by pressing the COAST button.
  6. Push the brake pedal to disengage the cruise control function. If you wish to return to the previous set speed, use the RES (resume) button. You must be traveling at least 30 miles per hour for this function to resume.
  7. Erase any previous speed by pressing the OFF button.

Wiring issue on a 1965 Roadrunner Travel Trailer


Generic comments follow:

I'm not real clear on what you are asking ... I can almost guarantee you that you will not find a wiring diagram for your trailer.

Your travel trailer operates on 12 V DC. Your frig, the heater, all the lights, radio, all 12 volts. Your running lights should be getting power from the tow vehicle. While towing, the tow vehicle should be charging the battery. You may find some 110 volt lights inside, but probably not. To keep your battery charged, you have 110 Volt AC power coming in. Your frig may run on 110 V AC but it still needs 12 volts for control. Your Air Cond and Microwave and TV (if equipped) will al,so run on 110.

Regarding the three wires from the battery, there should be a battery charger close by your 12 Volt fuse panel. Even though the trailer is a "vehicle" dont depend on using the frame as a ground like you would in a car. So, that accounts for two of the three - a red or black and a white wire. There may be some dedicated line that the battery supplied to account for the third wire.

There should be a emergency breakaway switch on the front of the trailer. This is a switch with a pull pin. If the trailer breaks away, the pin is pulled out by the tow vehicle and the electric brakes should be automatiocally applied to stop the trailer. This switch should be powered, unfused, directly from the traailer battery and go directly to the electric brakes - presuming you have this feature.

Be aware, this trailer power supply was built and designed for a life style far different from that we enjoy today. If you have a 30 amp cord, as I suspect, 30 amps is enough to charge your battery, run your 12 volt items, run a TV and AC or TV and Micro or Micro and AC but not much else. As you are aware, you have two circuits built with #12 and they are probably protected with a 15 amp breaker though the #12 would be protected with 20 amp breaker in a house. The cord is only rated for 30 amps and it may be tired, unless you have replaced it.

I hope I have provided a little insight to your situation. If I can be of further assistance, please let me know.
