Noticed oil cooling fan not working on hot day. Fan has power and checked all wiring, seems ok. Changed thermister switch and thermister probe that mounts in radiator, still nothing. Jumped power for fan and takes off right away. Also if I pull one of the leads from the temp probe to the thermister switch, fan comes on. Is there a fuse somwhere on this model I don't know about? I've traced the wires and can't seem to find anything that would cause this.
