Charging system/instrument cluster
Hey guys, i have a question for those who really know the instrument cluster. When we got the car, (87 240), it had a 'dead' alternator, after that was changed and it didnt fix the system, "we" (previous owner) had drained the battery enough that it didnt hold much of a charge, so that was changed. Checked the ground and the lead from + battery to alternator, ohmmeter reads very little reisitance, and voltmeter is in the mid 12-s... so, its still not working problem. Then I got to thinking, on our last car, the same thing happened,but it was after the instrument cluster had died, (read shorted out), so before i shell out more money for that, does anyone know either a way to check that part of the circuit, or a way to work around it? Thanks

well, checked the bulb, car=dead, so it wasnt very bright, but the oil light, which was next to it, was much brighter, so i switched it with the battery light, but same results... oil bright and battery dim...
also, assuming that autozone testing is accurate, then the alternator works, but... its autozone

bought 'new' in july when we got the car, hasnt worked yet, wondering what it would take to rewire the whole circuit just so i can pretty much make sure because the alternator and battery have been tested, but currents getting through, so... technically nothing is wrong ha

well.. got a new problem, took out the cluster to make sure bulbs were working, and when i plugged it in again, i was getting movement from the speedo (ie car in run, engine off, and going 30mph+) so i figured that it was related to the battery being almost dead... so i charged up the battery and tried it today, no starting. I let it sit in run for a bit in between tries of starting it and the instrument cluster started smoking. So i pulled out the cluster again and checked to see if perhaps i had mixed up something, but from what i can see, nothing. All the wires seem to only have one possible connection except for two that appear to connect to the same piece. It has two prongs for the connection, one each, and so i hooked it up again, and same results. Moving speedo and after a minute or two i get smoking. The car will also not start. It just cranks and i can smell fuel after the 10th attempt of starting the car, so i think its more of this electrical stuff...
