One side of the breaker if for the A/C and the other is for the GCI outlet. The insulation is also melted on both wires close to the breaker. The insulation looks OK on the other two.

The Onen PDF manual I have says to adjust the governor for over voltage but does not say where it is or how to adjust it.

Is this something I can do?

How do I do it?

Onen BGE F series 1988 P30 Chassis

The switch on the dash is the deluxe, it has an hour meter and a rocker switch. The switch worked before I put the new interstate 6 volt Golf car batteries in it. Now, only the "off" switch will work. I must start the unit from outside.

Are these switches still available?

Thanks in advance.

hi,i'm an ex onan warranty station owner, the gen set MUST be set at 1800 rpm , that will give you the proper voltage at 60 cycles. DO NOT try to speed up or slow down the gen set as it could burn out the armature. hope this helps you.

engine speed must be set with a tach. if you over run the speed you will burn out the gen ! speed MUST be set at 1800 rpm inorder to get 60 hertz ! i was warranty station for onan, an onan dealer has the proper equipment and should check the rpm for free for you !

So, I just need to adjust the idle screw while watching the Hertz? I don't have anything to measure the RPM's with.

Thanks for your help.

I owe you a beer mate!

I'll get a new Ammeter over the weekend and check, BUT MY MAIN PROBLEM IS FIXED!!!

A friend hooked me up with a tach. I set the RPMs to spec and low and behold, the Hertz are dead bang on 60 and the voltage is 120. The generator purrs when the A/C is on. You can barley hear it. Man, I'm so glad I joined up here. You guys are great.

Thanks to everyone who posted here.

I hope this will help others. RV safe mates!
