Well, yesterady the fan stopped working. I don't know what part of the relay/temp system failed, but it did. The fan itself is working great, found that out and just hooked it up to a toggle switch for now. Hopefully it is the relay and not the temp. probe that went bad. The relay can be replaced for about $6 but temp probe cannot, its integrated into the wiring harness. The relay just gets unplugged and replaced. I gotta do some testing to figure out which component is bad. Then, depending on what went bad, I may go with a different set up. This thing failed way too soon (third ride) and I didn't beat the hell out of it neither. so what was the culprit to the failure?
