I have an old JD 330 diesel lawn and garden tractor that blew a 10 amp fuse first start of the season. Front PTO disengaged. As long as pump is not hooked up it stays engaged. The electric pump was not working and got another. It lasted only a few minutes. I thought they had given me a defective one. I got another and put a fuse on the hot line and the pump blew the fuse and the pump got so hot you couldn't touch it without getting burned. I checked the following while the tractor was running. Voltage at battery 18 volts DC, voltage at hot lead that goes to electric pump fluctuates 16-18 volts DC. Output of alternator shows 25 volts AC. DC voltage looks high to me. Output of alternator, I don't know what its supposed to be. What do you think? Bad regulator?
