Title: Coolant fan Post by: prenfroe on March 20, 2004, 02:12:31 am My 84 2m4 coolant fan is hardwired directly into the passenger copartment near the fuse box--but there the male end simply hangs down! (Sorry) What do I plug it into to? The fuse box offers me ign, pwr acc, batt--I am told I need a 20 amp slot but none of these are marked with # amps.
Title: Re:Coolant fan Post by: dguy on March 20, 2004, 10:16:16 am Hmmm... if a former owner did that, I'm guessing that a component in the circuit which normally switches the fan on/off as required failed. My personal preference would be to locate the problem in the original circuit and repair it instead of band-aiding, but it's your car not mine. :-)
The ideal "band aid" repair would be to have the fan run whenever the key is "on", but not when in acc or off. I can't remember if the ignition take-off on the fuse panel is fused or not, and if fused what it's rated for. Unfortunately the fuse panel diagram I have doesn't appear to list any of those take-offs either. Unless you can find this out, your safest bet would be to pick up a generic relay from your favorite automotive store, and use the IGN terminal on the fuse panel to energize the relay. Run a (20A) fused line from one of the BATT terminals to the switched side of the relay, and connect your fan wire to the "other side" of the relay's switch. |
