Repaired temp compensating board 200 86

posted by  someone claiming to be Don Foster on  Sun Oct 22 04:25 CST 2000 [RELATED]

After driving for 3 months with a dead temp gauge, I finally dived into the compensating board.

Yes, I first checked the other stuff—thermostat, voltage regulator, sensor, wiring, connections, and even the gauge. All were OK.

I replaced the LM2902 quad op amp and the PNP transistor on the comp board, and —— temp gauge back to normal! I don't know which of the two was at fault, but since I have a supply of each part, I didn't care to spend the effort debugging to the actual part. In goes the new, out goes the old.
