Most likely cause other than faulty wiring or bad ground is a faulty inverter. the specs should be taped to a panel near the unit or folded up nearby depending on the tech that installed the unit. use a voltmeter to confirm proper operating thresholds (if no spec sheet is present you can get one but contacting the manufactuer and providing a model number)

SOURCE: 12 volt power to 7way plug to camper no power fuse

If you will look at the under hood fuse block towards the rear there is a large red wire with an eyelet on it. It should be taped to the harness. You will need to hook it to the hot post under the lower cover on the fuse block.Remove the fender beace from under the hood and remove the cover. At the front of the fuse block there are 2 posts. Connect the wire to the hot post with a nut usually a metric 8X1.25 thread. Good Luck

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.

I justr change the window regular and when starting it only clicks


It sounds like your battery went low while you were replacing the window regulator with the door open and the dome light was probably on draining the battery. I would check the battery voltage with a volt meter to see if it has 12 volts in it. You might have to jump start the vehicle and let it run for 30 minutes or so to recharge the battery. I hope this helps you.

The car soulds like the battery is low but when it starts the flashers come on.


Often an alarm system will register a low battery voltage and presume the vehicle's battery is being removed to prevent the alarm from going off. They will then begin flashing and or sounding the horn.
In your case, I would presume that the battery voltage is too low which may indicate either a failed battery, or a parasitic voltage drain.

First, get the vehicle started, and run the vehicle for a good twenty or so minutes to get some charge to the battery. If you don't want to waste fuel however doing this, then I suggest using any battery charger, as all we want to do is get some voltage back in the battery. If you are using a charger though, then charge on a lower voltage setting overnight.

Once you have the battery charged, run off any surface charge by turning the vehicle lights on for a minute, then turn them off again.

You need an ammeter for this next part:


Disconnect the battery positive terminal and connect the ammeter in series with the battery and positive lead.
DO NOT ATTEMPT TO START THE VEHICLE!

With all vehicle systems off, the key out, doors closed and alarm 'OFF', bonnet close switch depressed, or bonnet/hood clasp closed (need a screwdriver), take a reading from the ammeter.
After probably no more than twenty minutes, the ammeter should be reading 0.03 amps and not much more. Anything like 0.5 or 1 amp means you have a battery drain.
If this is the case, then start by disconnecting the alarm system. If the alarm system has it's own separate speaker/horn, then disconnect this first. Many of these horns have backup batteries, which only last three or four years before they fail, which causes them to constantly draw from the vehicle battery and then flatten it when parked.
Every time you disconnect an item or system, check that ammeter again to see if the amps have returned to normal. Pull fuses one by one, checking the ammeter each time for any change until you find the system which is causing a drain, then attend to that system.

If your amps are normal however and your battery is still loosing charge when parked for any short length of time, i.e. a few days or so, then your battery is at fault and requires replacement.

Just before changing your battery, do one last check, which is with the vehicle running. You need to reconnect any battery cables, and start the vehicle. Using the voltmeter once more, check the voltage across the terminals with the engine running. This is your charging voltage and it should go up to around 14 volts if revving the engine slightly. If still around 12 volts only, then you have a charging issue, which is probably the alternator.

Looking for manual or information my 1988 TravelAire Camper van. It is on a Ford e-250 chassis. Need to know how the 120 Volt system works; i.e. does it operate all lights (including 12 volt); does it...


Typically, the 110 Volt will go into a power center which should include a small amp battery recharger. Your 12 volt lights should run off a 'house' battery which should be isolated from the truck battery, yet, the truck alternator should charge the "house" battery on the road. The device that allows this is called a Isolator. You may find a manual switch instead. You definitely don't want the house and truck battery to both run yourf coach with no recharge capability. Some systems have a 'emergency start" switch which allows you to use the house battery to start the engine. All 12 volt house stuff should run off the house battery and the battery should be recharged by the truck or the small battery charger. Do you have an evap frig? Runs on propane or electricity? It needs 12 volts whether it is running on gas or 110 Volts. The 12 volts runs the control panel and the heat to make it work is supplied by the gas or by a electric calrod if 110 is available.

I am pretty familiar with these electrical systems ... I seriously doubt you will find any information on your 20+ year old motor home. Typically, the printed specs and equipment and the data is obsolete before the ink is dry because the manufacturers use what is available as they build. If you have additional questions simply click on the "add comment" or the "reply" link and I will take a look-see.

I hope this answers your current question. Thanks for your interest in FixYa.com

You shoulld expect more than 12.8 volts from the alternator up to nearly 14 volts when charging a low battery. The battery can only show the amount of voltage your alternator is sending to it after being used for a while. I would suggest that you have the battery tested & recharged completely, your voltage will be above 12 volts and if it returns to below that , you will know your alternator is not charging. Also, if you test the output of the alternator and see it is below 12 volts after the battery is fully charged at 12+ volts you will have confimed the problem also.

good luck.

My low voltage light came on in my 2002 volvo s80. I just replaced the battery. Is is something else than the battery?


the alternator. have it tested as if it iis failing the car will run off of whatever voltage is left in the battery until it is consumed as the alternator is supposed to recharge the battery and supply the power for the cars components

Engine won't start. Dash lights flash rapidly when key turned.


the battery says 12 volts but may be dropping to 4 or 5 under a load...i would suggest jumpstarting the car and see what happens.the battery should read in the high 12 volts and not less than 9.5 under cranking. the dash lights go out on your car when starting,and the alarm will go off ,and disable the ignition if the voltage is too low in cranking the car because the computer will shut it down and activate the anti theft.....check your battery posts are tight. best of luck

No running lights on camper trailer


Hey Paul, it's most likely a wiring problem. There is one wire designated for just the running lights. What type of plug does the truck have? Probably 6 or 7 way (6 or 7 wire). You can check the plug-in at the truck with a multi-meter to see if there's power at that point. If there is, then the problem is somewhere from the trailer plug to the lights on the trailer. If you have a 7 way plug, the center plug is for aux. power (back up lights on what you pull, if equipped). One wire is power to the camper battery for a breakaway switch, one for left turn and stop, one for right turn and stop, a ground wire, one for running lights, and one for trailer brakes. To determine what wire does what, 1st with meter check volts of all wires w/ truck and trailer hooked up, truck running, power wire to battery for breakaway should show voltage if equipped w/ a trickle charge, brake wire will show low voltage, approx. 2 volts, apply brakes and should go up to approx. 12 volts, put on L turn signal, meter should go up and down, as power to blinker pulses on and off, do the same to determine which is the R turn signal (put foot on truck brakes will show voltage to brake lights AND brakes, continue w/ process of elimination to determine which is running lights, and exactly where power is not going.
