Predator 9000 problem

I have a strange problem with my Predator 9000. I have an electric start on it. The electric start works fine and the generator runs and puts out the correct AC voltage. The problem I am having with it is on the 12v circuit for the starter. When the unit is running it is producing 25 volts to the white wire connected to the starter solenoid which has the positive cable coming from the battery. The white wire has 25 volts and is cooking the battery. When I disconnect the wire the starter relay will not engage but if I touch the wire to it it will. I know that this wire has to be connected in order for the starter to work. The thing I am having trouble with is where is this extra voltage coming from?


I have no problem with the AVR, Harbor Fright sent me a new one and after installing and adjusting it, it still producing 25 volts on the starter circuit. I have checked the rectifier and I have 12 volts DC for the 12volt plug. As far as I can tell there is only one rectifier on this unit. I do have a module that has a plug end on it and wires from it connect to the on/off/ start switch. The only markings on it are JB-DDQ. My manual says that it is a controller. The white wire from the starter relay is also connected to this plug end that goes to the module. 


I’m going nuts trying to figure where the 25 volts are being produced and back feeding the battery and cooking it. Has anyone heard of this problem or does anybody know where the problem is coming from.
Also, does anybody know what the module labeled JB-DDQ is or where I can get one? My wiring schematic says that there is two rectifiers on it and I am starting to wonder if this is the second rectifier. 

Any help in getting to the bottom of this would be appreciate.
