Been having problems with my 77 D100. Battery keeps going dead. Charged the battery and had it tested and was told the battery is fine.Thought maybe the alternator had a bad diode. A replacement alternator was only $25 so I replaced it. Same problem. Read Ehrenberg's bulkhead connector fix and ran a wire with fusible link from the alternator to the battery stud on the starter relay. Same problem. Bypassed the ammeter, same problem. I'm thinking voltage regulator. When I ran the wire from the alternator to the starter relay, I disconnected the wire that runs from the alternator to the bulkhead connector. Is that going to be a problem? Everything seems to work fine other than the battery going dead after a day or so of use. I'm at a loss.
