Wiring diagram for Generac engine on standby generator

How old is it???? Does it have a read out that tells you what's wrong?????When is the last time you did a maintaince tune up on it???? Mine is fueled by propane and I changed the oil and plugs and it's been fine since....Sometimes it's the starter/ignition..I would do a complete tuneup first, then clear codes, then try starting it up manually....If that works put it back on auto..Good Luck

First check:

Check the obvious battery
Remove spark plugs and try, make sure engine is not mechanically bound or seized.
Check the starter motor to make sure it isn't binding up

For the over voltage there is an adjustment on the control board.
Should be tested with a load something plugged in.
The hertz might just come on when under load and adjusted too.
If you need more give a model number and whether it is 13kw or 40kw.

I have a 15000 ultrasource generator the start and stop switch was taken out i need to put it back The problem is i dont know which wire goes where and when i look at the wire diagram the numbers are different the numbers on my unit are 15, 11, 133, 14, 12, The 15 and 11 are the same wires the start and stop switch has 6 males on the back to plug the wires into Does anyone know which wire goes where???

Just happened to find a copy on-line for the Generac V-Twin GT990 Engine Service Manual.
E-Mail me : [email protected] and I'll send you the PDF File for that. Good luck with your repair.

If the area you live in has alcohol added to their unleaded gas, then you will probably need to rekit the carbuerator. Also check the spark arrestor for plugging up. Try to find a non alcohol, off road unleaded gas for your generator.

yes but wil only work if gen is h/wired 2 a/c

I am assuming the generator worked fine before the oil change. Now that you have done the oil change the genset does not start. These generators have a safety switch, which is basically an oil pressure switch that keeps the engine from running when there is not enough oil in the engine. Make sure that there is enough oil and if there is, look for a wire that runs along side of the engine to a round component. disconnect that wire and try starting. If it does not start then try to ground out the wire to the engine block. If this does not work, then there is other engine problems.
