A group of friends and I went camping with my son and his 1984 van 2wd in Soda Springs this weekend.
His temp gauge recently stopped working earlier this week. We did a ohm test on the sensor and it was open so we ordered one from Carquest, it did ohm but no response on the temp gauge. At the time we didn't think there was a cooling issue. On the way home on HWY 80 just before Roseville everything went crazy. The alternator light came on along with the parking brake light, the door is open light. and it began to loose power. When we got on the surface streets he could hear a clicking noise when he would accelerate. We went as far as we could until the battery died. Has this happened to any body else.
1. How can I test the Temperature gauge?
2. Is their a specific temp gauge sending unit or does any body know what it should ohm at?
3. I have read it here about the alternator harness going bad or something. What am I looking for?
