Re: wire size on relay

I had to change 3 of my electric fan relays to a larger relay and a larger wire and for a 12vdc source, I used the Alt. for the supply

The A/C cycles and then the fan cycles and the relays were getting hot and then the connection at the fan was starting to fatigue and then finally, I lost a fan because of low voltage and bad/open connection

The stock relay and wiring harness I am only using for the trigger for the new heavy duty
relays and wire 8 and 10AWG

We will see how this summer goes!
