Bench Test SP1 Fan
My radiator fan is dead so I ordered a used one that was removed and supposedly in working order. I am trying to test it using a battery before I put it on the bike and can not seem to get it to work. I would like to confirm it is working properly before installing it on the bike. I had thought it should be as simple as connecting the ground wire from the connector to negative on a known good battery and jumping the third wire to the positive. The fan actually has three wires coming off of it, two running to a connector and a third wire that is separate (+)? Am I correct in assuming the fan should come on when connecting the third wire to the positive side of a known good battery and the ground from the connector to the negative side of the battery? Tried that and fan does not come on so wondering if the fan motor is bad?
