Every wire and electrical control on my 69 Charger has been replaced or rebuilt. Not sure if this is a issue, but I have never seen quite as much ammeter needle movement as I am having with this car. Everything works fine, but at idle the needle will bounce up to charge when the brake pedal is pushed and does the same every time a turn signal lights up - it drops back down immediately. Can an ammeter just be overly sensitive? The service manual says excessive resistance in the regulator wiring circuit will cause fluctuation in the ammeter. So I did the test by the book by measuring the voltage from the positive side of the battery to the field side of the regulator with the coil unhooked. If the reading is over .55 volts, this indicates high resistance. I got 1.1v. They then say to backtrack to the battery until you find a sudden voltage drop. On the ign side of the regulator the voltage is .1v. That is more what they are looking for. I am using a solid state regulator and even tried another new one with the same results. I'm thinking the voltage drops would have been different with an original style regulator, so maybe this is all normal? The ammeter has been restored by Redline and I have greased and rechecked all the wiring connections. I should mention that I also installed a Mopar electronic conversion kit. Anybody ever dealt with something like this before?
