Hey all,
I've finally got around to doing some work on Burt. Replaced the temp sending unit and while I was at it flushed and replaced the coolant, since I had to drain the radiator anyway. I have one item that has me stumped though. I'm usually pretty good with 12V electrical, but I can't figure this one out. I want to test the ammeter. I know that it's a shunt type from my shop manual and under the testing section it states to "check the battery to circuit breaker wire connections" ? For the life of me I cannot find that wire or a circuit breaker or the shunt. Someone mentioned it was off the alternator, but I've replaced that a number of times and didn't see a shunt wire/resistor there. I really want to try this before I go through all the trouble of replacing the ammeter itself by taking out the dash. That's a pain to do. I know from replacing the brittle instrument pod a number of years ago. I searched further in the manual for the wiring diagrams, but I can't find what I need. shouldnt' the wire for the shunt come after the alternator? I can't figure out how to trace the wiring from the gauge back to the battery... I'm just so confused now!!!
Oh, and I know the ammeter is not all that reliable, I just want to keep the original gauges working for historical sake.. :-)

Thanks as always for your help!
