My thanks also!
My problem is with the voltmeter (1986 CJ7 factory guage). Needle doesn’t move—I put known 12 bolts across it and it still doesn’t, so I know the guage is bad.
What I can’t figure out is, with my multimeter red pin on the yellow wire and the black pin on a good ground, it reads bogus number-like 150. That’s with the key on. With the multimeter across the battery it reads about 13 not running, and in the 14’s running.
Shouldn’t it read the same under the dash, minus a small drop?
