Sorry there was a glitch and your question appeared where it shouldn't have
So, I'm going to open this backup to my colleagues so one of them can help. Please don't respond (even to acknowledge this post)until you get a response from us. If you respond first it will only delay your answer.
Hello, my name is ***** ***** I am going to assist you with this.
I need to know one thing before we start here - do you have a remote start switch connected to this genset, or do you have to physically go to the genset to start and stop it?
Battery charging is not accomplished through the control board. If the genset is starting and running, the board is good.
Battery charging on this unit is done through a resistor and a diode - they are what usually fail.
But before even thinking about changing any parts at all, you need to measure the voltage and frequency output of the unit, with no load on it. The genset may simply be producing too much voltage.
Connect a meter to the AC output leads, and start it up.
What voltage reading do you get?
What frequency reading do you get?
Unplug the remote switches from the genset.
Does that allow the genset to operate properly?
