I have a 7000kw B&S generator. The engine will not turn over. I replaced the battery with deep cycle 12 volt 35 and it will still not turn over. Any Thoughts Thank You JerryG

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.

1. Check the operation of the charging system warning indicator lamp (instrument cluster). Normal operation is as follows:
   • With the ignition switch OFF, the charging system warning indicator should be OFF.
   • With the ignition switch in RUN and the engine off, the charging system warning indicator light should be on.
   • With the engine running, the charging system warning indicator light should be off.

1. Verify the battery condition. Refer to Section 414-01 .

   Your whole problem is the alternator is not charging , a couple tests with a volt meter would tell you !

Size U1 gel or SLA (Sealed Lead Acid). 12 volt 32-35 Amp Hour.
Best brands are MK, PowerSonic, Panasonic, Universal UB12350, and FIAMM.

to increase amps your best bet is to get two deep cycle marine batteries with high cranking amps

Hi
Assuming there is nothing wrong with the inverter or heater.
You need to check the voltage on the input clamps of the inverter (+ & - connections on the back of the inverter) when going under load, if the voltage is going under 12 volts as it is applying power to the heater there is a connection or volt drop issue.
The inverter is capable of drawing up to 190amps from the battery this can cause damage to the battery.
It is very rare for an inverter of this size to be used on 12 volts.
There are a long list of calculations which I am not going to bore you with, but for this inverter to run on a 12 volt battery system and not cause unesesary damage to the batteries you would need 8 x 120AH deep cycle batteries.

12 volts but you have to do the following in order to run your amplifier with out any problem
Upgrade the alternator to a high output alternator. Upgrade to a heavy duty deep cycle battery
Upgrade the "Big 3" - that is to replace the power wire between the battery and alternator, the ground from the battery to the chassis and the ground strap from the engine/tranny to the chassis with at least 1/0 AWG wire.

Please understand that the generator produces power from fuel with an engine wheras the invertor is one which genrerates power from a stored battery using the principle of frequency switching a DC source to induct and produce AC.
Now you can have an uninterupted power supply setting with the invertor backed up by the generator so that when the battery voltage goes down you can start and charge the invertor and also supply the extra energy .
the ratings of both must also be considered.

Hi. What size batteries you buy will be limited to the amount of room you have in the machine.
17 amp hour batteries are really a bit small for any mobility equipement. A lot of power chairs have 35 or 40 amp/hour batteries.
Buy the biggest that will fit into the available space.
Batteries are designed to perform a certain number of "charge cycles". If you run your batteries down by 75%, you will only get a small number of "charge cycles". If you only use 25% of the batteries capacity, you will get 100's of "charge cycles".
The best I have seen is 7 years out of a set of batteries. Short trips and recharging after each trip is the reason.
Good luck. Neil.

Keep in mind a blown fuse indicates and overload situation.
There is a short somewhere in the system.
Have the wiring system checked.
Things you can do yourself,
1. Check for water collection in the turn signals or instrument panel.
(If found dry out and seal to prevent repeat contamination)
Blinkers easy.... instrument panel you may want some professional.:)
2. Turn on blinkers and twist the handle bars full left then full right.
If the fuse blows during either of these two operations note which one.
Left or right then check the wiring running to that blinker. You may
find the short this way.
3. Check the battery before and after engine start up.
Your voltage should be around 12.6 volts rested. Engine not running.
Your voltage will probably be 13 volts Plus with the engine running.
Over 14 volts this could be why the fuse is blowing.
Have the rectifier checked.

Gel-cells resting voltage 12.9 to 13 volts

The basics:
First things first. A 12-volt battery is not a 12-volt battery. Twelve volts is just a nominal, convenient term used to distinguish one battery from another. A fully-charged 12-volt battery, allowed to "rest" for a few hours (or days) with no load being drawn from it (or charge going to it), will balance out its charge and measure about 12.6 volts between terminals.
When a battery reads only 12 volts under the above conditions, it's almost fully depleted. Actually, if a battery's resting voltage is only 12.0 to 12.1 it means only 20 to 25% of its useful energy remains. It's either a goner or it has been deep cycled, and a battery can only be deep-cycled a limited number of times before it is indeed dead.

Hope this helps!

Yes, just be sure connections are heavy enough wire, and obviously the inverter uses 12 vdc input. Hook jumper wires positive to positive, negative to negative, on all 12 volt batteries. Deep cycle batteries will work better than car batteries. Just remember, when re-charging them, that they last longer when charged slowly, so don't use a high amp setting on charger and to monitor them closely, and do it in a well ventilated area, away from any ignition sources.

YOU NEED TO REPLACE THE SOLENOID IT IS SHORTING OUT AS TO THE GAUGE THEY WILL NEVER MOVE AS THE GENERATOR CHARGES ONLY WHEN THE BATTERY HITS 9 VOLTS THEN IT ACTIVATES TO CHARGE BACK TO 12 VOLTS BUT IN SMALL INCREMENTS
