I have been working today on my genset to get it running. It blows the 8amp fuse at the control box. I thought it was the oil switch at first, then the exhaust temp switch, but now not so sure. Looking at the wiring diagram they are wired in series first oil, then water, then exhaust. I started by unhooking all the wires from all 3 then plugged them in in order and fuse blows once last switch is hooked up. Now thinking that this is because it completes the circuit. I’m now questioning if it is any of the 3 switches or just the wiring? Any ideas on how to isolate the problem. If I have any of the 3 switches power unhooked I can start the genset because the fuse does not blow so then I can hold the down preheater and start the genie since it also bypasses the switches but then it dies when I let go of the preheater switch.
