stupid question....temp gauge and sender, temp doesn't register...where is sender? Options

[jim912928]

Ok, my temperature gauge doesn't register at all. Car runs fine, but I really don't want to run it long without knowing what temperature range I'm running in. So, I need to begin diagnosing this problem but first I'd like to know where in the heck the temp sender is located? I'm guessing it can only be 1) wiring, 2) gauge or 3) sender. So, once I find out where the sender is how do I test it?

Car is a 75 1.8l....again, as usual...thanks in advance!

Brad,

I went out again and looked at the main wiring harness under the battery tray....moved it around alittle and running underneath it was the greenish wire with a male connector at the end of it (about half way up the harness right under the battery tray.

So:

1. I have the wire in the rear engine compartment
2. My taco plate has the "bulge" on it with a hole for a sender
3. guess I'll have to really get under the car so I can see if there is indeed a sender in there (can't feel anything via the tip of my finger)

Thanks again for the advice on what to look for. If I'm lucky, there is a sensor in there and I only need about 2 feet of wire!
