Problem wiring up Mark VIII fan w/ relay
I have a Mark VIII fan and a 75 amp Bosch relay, and I'm switching it on manually through a toggle switch.
I hooked it up according to a diagram I found on a Ford site and figured everything was correct.
This is how I have it wired through the relay: One wire directly to the battery through a 30amp fuse. One to a 12+ ignition. One to the fan. One to the toggle fan switch.
I can turn the fan on without the ignition on. When I have the car running the fan will not turn on. If I turn the fan on and then start the car everything is fine until I turn the ignition switch off and the car and fan continues to run. UH OK! So I turn the fan off and the engine shuts off.
I'M CONFUSED! Help Please!
