Coolant temp sender wire
Hi all,
Does anyone know if the wire from the temp sender emerges from the harness anywhere en route to the gauge. I'm trying to track down a low reading gauge issue. The sender resistance checks out ok. So either the wire or the gauge itself is at fault. I'm a little annoyed (at myself) because i just had the cluster out to replace the bulbs with led's and cleaned every connection while in there but forgot to do a definitive test on the gauge (yes it was reading low before). If there was an easy way to test the wire without pulling the cluster again it would be nice.

That is so, the a/c compressor trigger wire also runs down the V, maybe in your case in a common outer.

Well after all that it turned out to be a crappy connection at the sender. I figured one more test before further investigation. I disconnected from the sender and substituted a 50 Ohm resistor to ground. Hit the ignition and the gauge move to N, dead on. If I have it correct that means all is well from the connector to the gauge, leaving only the connection. Cleaned up the connecting surfaces with emery and finished with a dose of deoxit gold. Ta-dum, all fixed.
