We had to do a engine swap on our 2003 Kubota RTV 900 because one of our employee's blew the engine up by running it with no oil :ashamed:
Anyway, brand new motor installed, everything is working good except the alternator and electric fan aren't working right. I traced the wiring back to the same switch/relay on the back of the cab and it seems the alt and fan share this relay. I checked the fuses and replaced a blown fuse that controlled the alt, and ran it again for about ten minutes, then another blown fuse. THought maybe a wire was shorting, unpeeled all the wiring harness and found no frayed or suspicious wires. One thing I need to question though, should the wire that leads to the sensor that goes into the waterpump and thermostat housing have 12v power? I was always under the assumption those sensors operated by grounding the circuit when it got to a certain temp?
