Dual Fans Help
Ok Fans were working perfectly three days ago. Now only one fan comes On. I tested the fan motor by connecting straight to the battery, so the motor works fine. So I tested the pig tails. One pigtail works great! The other pigtail put out ZERO volts! I put a brand new relay and still did the same thing! So why would the pigtail just all the sudden lose power? One works one doesent! I traced it back through the wiring and nothing seems to be any different! Plus the pigtail itself isnt bad because I spliced into the wires and tested them as well. I checked fuses and everything! So in order to get the both fans to work I had to splice a pigtail to the good source. I hate to rig stuff up but I did it until I figured out how to get power back into the other Wire! Thanks

Wire? Shorts?

Relays? Swap with primary to test
Fan switch?
Lots more to check...

So if you ground the relays they work? Have a multimeter right?
