Electric radiator fans won't come on
I bought the dreaded eBay slim fans to try them out and plan on using them for right now. Can't afford anything else right now. I also bought a relay kit on eBay as well. I wired it up like this. 16g brown wire from relay goes to 12v ignition source, 12g red wire goes to auxilliary side of the breaker, 16g black wire goes to temperature switch and the other 12g red wire goes to fans. And a 12g red wire from batt. side of breaker to pos. side of battery.
The slim fans right now are wired up 18g blue to ground and 18g spliced together to 12g red wire butt connector. I have done it vice-versa, too. 18g black to ground and 18g blue to power 12g red wire. Nothing. What am I doing wrong here?
Also, I had to use galvanized fitting for the temperature switch from the radiator, because I didn't have the proper 1/8"NPTM x 3/8"NPTF fitting at the time. Could the temperature switch not be grounding?
Please help! Do you need any photos?
