Can you answer savis07’s question about Generators?:

I have a Onan Microlite 4000 RV generator and I have changed the starter, fuel filter, and fuel pump. I’m getting power to the positive end of the solenoid, but no power to the starter. When I press the start switch there is a clicking sound but the starter does not engage to the fly wheel(the fly wheel is free). I am getting no power to the to the starter poles. I touched one end of the positive side of the solenoid to the other pole of the solenoid and I got sparks. I’ve checked all connections, is it a possibility that the voltage regulator is bad or is it something else?
