Jon: Yes, the fan motor is toast. It will turn even when connected directly to a battery. I have a new spare fan since the manufacturer mistakenly sent 2 and then said keep the spare since they didn't want to pay for return shipping. The radiator, shroud, fan, wiring harness and relay are all from Champion Cooling. The manufacturer recommended a 30 amp fuse. Instead of adding a fuse, I kept the 30 amp breaker from the previous fan install. I discussed the substitution with the manufacturer and they didn't think it would be a problem.
Buoymaker: At this point I"m not sure what the voltage at the battery was. I'll check Monday. Yes, the engine was running when I checked voltage at the fan connector. No apparent electrical problems before I installed the radiator and fan.
So, should I be using a fuse instead of a breaker?
