Re: WJ Raditor fan relay woes
If you dont have any way of measuring the current the fan is drawing then I would replace BOTH the fan and the relay with new. If it works with a new relay it is a pretty good indication that the circuit is intact. As frank said, the fan will draw too much current and kill the relay. that is the ONLY draw on the circuit, so if it works with a new relay you know there is not a short and the wires start and end where they are supposed to, the only current decider is the fan.
