what would cause the temp gauge in my 1985 Ford E150 to go to hot when lights are turned on, wipers are turned on, brake pedal is depressed, heat is turned on, or van put in reverse?
when I start the van and run it without running any of the "accessories" the temp gauge
stays right in the middle of the normal range. However, when ever I turn on just one of
these "accessories" ( headlights, interior lights, brakes, heater, wipers, reverse lights) the
temp gauge moves quickly to hot. Engine is not overheating when this occurs.
Sounds like some sort of wire shortage.
that is what i was thinking. Any thoughts as to where I should look for the shortage?
Man that could be a mystery!! I would start with fuses first. Pull out one by one or perhaps all the fuses and see which ones are the culprit. Otherwise your chasing wires in the endless speggiti bowl
I was afraid you were going to say that. Thank you tho for taking the time to answer my question. I really appreciate it
Hey at least your not redoing 91 mit's 3000 r&r motor belts pump motor mount clutch axles the whole 9 yards! LoL
That's going to be a bad hot wire somewhere. A bad ground would force it to cold. HTH. - Jim
thanks Jim. That does make sense. Any suggestions on where to start?
You're welcome. Glad to help. I'd start at the headlight switch. In one way or the other everything you mentioned is connected there. Either by the illumination of the dash, interior lights, etc. I'd definitely check the fuses for these circuits as well. Sometimes if one blows it can upset other circuits by letting power "bleed" through. If you have and aftermarket stereo. They can be a source of trouble as well. HTH. - Jim
thank you again Jim. I will check those items out and I will keep you posted on the outcome. Thank you again. I really appreciate you taking the time to help.
does anyone know what the relay on the passenger side coming from the computer is called?
