Fan not turning on

[butch27]

I can hear my relay clicking but the fan won't start spinning.  Have a 180 thermostat in a 302 Ford.  Never over heated until Friday.?? All wires are tight.  Help   Thanks

Is the fan shot? Have you tried a jumper direct to it?

check the ground connections at the radiator core support..

the mustang electric fans are grounded there along with a BUNCH of other things..

there are grounds at both end of the core support..  usually green...

i have found the wiring to the ring terminals frayed and broken.. limiting the amount of amperage getting to the fan..

remember.. in a car.. a ground is HALF the circuit .. not a safety circuit


edit..   now that i think of it.. you have a 302 in rod of some kind..

you might want to open the relay and manually close it.. see if the contacts are your problem


what year are you working on.. i will be able to link a wiring diagram..

i have also on some fords.. that use a black square plastic box for radiator fan control..  had the contact support plastic melt so when the relay closes..  the contacts DON'T touch..

Wayne: It's still my old T-Bucket . The wiring is pretty darn good if I say so myself.LOL Got to do some tests today.

Tested the fan--It's only the relay.  Good.
