92 Explorer electrical problems
Temp gauge acting oddly after replacing radiator, heater hoses, fan clutch, serpentine belt, thermostat, fan clutch, upper and lower radiator hoses and temp sending unit (not the computer one). Heater core has plenty of flow. New coolant. Gauge may go to the 50% mark, but then backs off to about the 40% mark. If left to cool overnight it doesn't drop to C, but rather stays at the 25% mark. I ground the single wire and it passes H. Worked fine until I gutted the system. The fuel gauge also acts funny. With key on it goes to empty. With key off it will stay at about the 25% mark even with a full tank. Grounded it and it goes to above F and stays. Mechanic said it was the instrument cluster-bought a used one and installed-no difference. Alldatadiy says there are 9 grounds and I've located 4 so far. He also said it wasn't a sender going bad. Radio plays intermittently-mechanic said since it was stock I was lucky it lasted this long. Rear windshield wiper makes half a sweep and stops then kicks in maybe 20" later-mechanic said a short. The only add on is a keyless remote installed 10 years ago which works fine. I'm stumped. Any hints would be appreciated.

It's the "worked fine until I gutted the system" part of the post that threw me. What the hell did you do? I always trace backwards to see what I changed if something don't work right. Look at the wiring diagram for commonalities. A common ground or power source to these devises. There's a logical explanation somewhere.

Jharger,
This is the part that stumps me. The only electrical related technique I followed when I gutted the cooling system was disconnecting the negative battery terminal. This way I didn't get caught up in the fan clutch, etc. Safety first. I even replaced the fan clutch and fan blades. It has to be something obvious, I just haven't thought of it yet.

too late. need to think about this. nothing changed was a direct elecrical source. wonder if something else got knocked out in process. what is common electrically to these circuits? sometimes we cause a new problem when we are working on an existing one.

Something getting knocked out would be my guess too. I just went and looked at my 92, and it looks like there's a wire bundle under the radiator near the top. I hate to say it, but if it were me, I'd remove everyting again and take a look at your wire harnesses. (Save your antifreeze!) There's just too many things wrong for it to be just one thing...unless, of course, it's a ground problem.
