SOURCE: i have a kohler rv generator that will start .

When this happens, this usually means that your genset is not creating voltage. First thing I would do is disconnect your remote start wire from the genset, this will eliminate the start switch inside the RV. For a shorted remote start switch can cause you genset to shutdown. Second, place a volt meter at a spot where you will be able to read genset voltage. If no voltage is available and your voltage regulator is new, then the problem is with either the rotor or stator. The rotor is the easiest check. You need to reach the brushes. Take a resistance reading, which should be around 20 ohms. Clean the rings and make sure there is enough length on the brushes, at least over 1/2". Next, flash the fields using a 12Vdc battery. Use rubber gloves when doing this. Place the positive side to the ring closest to the bearing and negative goes to the back ring. This is done while genset is running so be careful with rotating parts. Have a volt meter on the output wires. Once you flash the fields the voltage should increase to over 50Vac. If it does then your stator is bad since you installed a new voltage regulator. If the voltage does not increase when flashing, then the rotor is bad.

First thing is to check oil level as low oil pressure will shut it down.

Check all the ground wires and make sure their not broken or loose. If the wires are good next check the neg. Wire to the coil. Too check the swiitch make sure you have continuity too all the post when the switch in the on position, this requires removing the switch.

I have a kohler 23eozd marine gen set thatwowouldn't crank. There's voltage 12.8vlts coming all the way to the sttarter but still wouldn't crank.


on the starter of the engine there are two teminals that should have 12volts to them while its cranking (or trying to) one has a 3/8 bolt stud and has a large wire/cable that should go to either the battery disconnect or direct to battery , the other one is 1/8" size and has a smaller wire to it , this is the trigger wire , it triggers the starter to operate , your going to need to look at those voltages when its trying to operate

Why onan 7500 HDKAJ rv generator will not turn over.


If the start battery is definitely good then why is the starter not getting energized? Ignition switch? Low oil switch, on/off switch? Safety switch?
There is something that you are overlooking. Bet that if you take a wire and hook up one end to the + terminal on battery and the other end to the plus wire on the starter it will crank!!!!!!!!

Onan genarator will not crank


If it wont crank, check to see if the solenoid on the starter pulls in, the starter and solenoid are one unit, it sounds like an internal starter contact, if you have 12V going to it. Assuming the battery is good. When you press and hold the stop button does the fuel pump pump prime? if so control board has power

Kohler RXT won,t start Kohler 20resa


Did you check the remote terminals and relay in the ATS, disconnect gen remote wires, kill the ATS brealer and ohm across the start terminals, they should close, if not a relay/control board issue, if they do fault is in wiring or gen control, or incorrect wiring

Kohler 12 RES - Unit fails to start occasionally. Attempting a manual start by placing switch in run position, cause a loud click, but no cranking. The panel says CC. This morning I put a jump start...


I finally solved the intermittant starting problem on my Kohler 12 RES by replacing the strater and the starter relay. I was also experiencing the occassional OC indication, red blinking LEDs on the ATS, and intermittent non-starts during the weekly exercises. The problem happened during power outages a couple times also. If I flipped the start switch between auto and run quickly the generator would occasionally start. Once started, the generator runs fine. I ordered a new starter, which included the starter solenoid. By the way, don't worry about the genuine part thing..the old starter was a Delco made overseas. I ordered a new starter online for $85 (6744N) and it was indentical to the genuine Kohler starter. Replaced the starter and it improved the problem but did not totally solve the intermittent starting. Ordered the starter relay (GM49746) replaced it and the problem is solved.

The car won"t crank, 1992 Volkswagon Passat


If the switch (neutral safety switch) is broken, it will not crank regardless whether you jump the battery or a new battery is installed. I don't have specific manual for your year that's why my advice is as in general. With a remote starter tool, bypassing the solenoid wire with remote starter which is connected to the positive terminal of the battery of it's other end. Once positive current flows from the battery, through the remote switch, flowing towards the solenoid, the starter should engage indicating a bad wiring harness connection from ignition switch. If it doesn't crank at all you may have a bad starter assembly and needs replacing. If your starter is clicking using it's own battery power, your battery is low of charge or your charging system is malfunctioning.

Pls, rate this suggestion, thank you.
