Thanks, guys… Appreciate the insight.
I was thinking that the temp sensor provided a ground to the light, but that doesn’t make sense.
Tying it to the output of one of the fan relays to provide a voltage source when the fan is active seems a lot more logical.
It’s really hard to follow those schematics (and I only have one for a ‘74), so I really appreciate the analysis.
John - for some reason I don’t fully recall right now, I have a red connector under the left side of the dash disconnected, with a jumper wire in it… is that connector possibly in this fan indicator circuit?
Thanks -
Chuck
