Hi All, I have a 77 300D where I have been having a problem where the battery is not getting charged from the alternator. I replaced the alternator and the battery still does not recieve a charge (I test using my multimeter). The battery is brand new and fully charged. I replaced the alternator as I should have, making sure the battery is disconnected when plugging the altnernator plug into the alternator and yet my battery is still getting drained.
I have tested the continuity from the battery to the alternator plug. I hooked my battery up while having the alternator unplugged. I put my multimeter in the terminals of the alternator plug and had a battery charger on my car battery and was able to get voltages from 12.2 all the way up to 13.8.
Upon reading the schematic I see that the positive lead from the alternator goes to the starter and then to the battery. Could there be a problem with my starter that is preventing the battery from getting a full charge? The starter does operate perfectly though.
Thanks for any help anyone can give!
