OK so i’m having a wiring problem from hell! My rad fan will NOT kick in anymore, i’m pretty sure my coolant temp sensor works because once it heats up both wires read continuity, completing the ground. i’m going to hook up the rad fan to ign pretty soon errr lol. both wires on the rad fan read 12v at all times, so it’s something in the control unit or the relay, how can I test the control unit and has anybody else had this problem and fixed it? how so!! thanks would be greatly appriciated if someone can help!
have you tried wiring the fan straight to power? if that doesn’t fly, you know what the problem is
when I hook up the fan straight to power it works fine, I have a toggle switch to my slim fan now but i really want to get it back to the stock system!
if you have ac, try swapping the relay. you can also test the relay by putting power and ground across the input terminals, which should give you continuity across the coil terminals
Helms manual ftw.
hey great idea, I have ac but it’s disconnected. is the relay for the rad the one on the passenger side behind headlight, and the ac has 2 on the drivers side a bit lower?
not sure. i don’t have ac. just follow the wires
