I have a Scag Wildcat zero turn with a Kawasaki liquid cooled 26hp engine. All of the wiring diagrams for it leave the engine out. I can't even find anything that says what start is has.
One of the odd things is that since this started happening, the water temperature gauge isn't working. For some reason, I think this is important.
I can mow for an hour, two hours, and one day, 3 full hours, without issue. But I have more days where I can only go for 20 minutes and the fuse melts. It doesn't just blow, the plastic around the fuse melts. The wires going to it are super hot!!!!! I've replaced the fuse and mowed for another half hour, ten minutes or a full hour, before it happens again. I've had days where I've replaced 4 fuses to finish mowing. But now it's getting worse. A lot worse!!!!
I traced every wire looking for a wear spot that might indicate a short. I've done this 5 different times and haven't found anything. Sometimes after doing this I can mow for hours. Today it was ten minutes and this is what the fuse looks like.
I'm starting to think that it's not a short, or a wire with a bare spot that's touching the frame somewhere. I'm starting to think that there is too much electricity going through the wires. My only guess is that my PTO Generator is overcharging and putting out more then 12 volts or more then 20 amps. The only time this happens is when the PTO is engaged and I'm cutting grass. I'm not comfortable putting a volt meter on it with the PTO engaged, but that might be my only option. I'll just have to be careful.
Something else that I noticed was that when I put my meter one of the two wires coming off of the PTO Generator, and tested for continuity to the frame and the engine, I didn't get anything. But when I put the meter on both wires, I did get continuity. Should that happen?
Is there something that I'm missing?
What else could cause this?
Is there a way to adjust the voltage coming from the PTO Generator?
Thank you
