I have a '55 T-bird, that has been converted to 12 volts (conversion done by a prior owner). Last week an issue started were the engine wont turn over or turns over a few times then stops. Ocassionally I can get it to start but not reliably, car was running fine before this issue (no warning signs that battery or starter were beginning to fail). I noticed that the negative terminal on the battery would get very warm when it would turn over. I jumpered the positive batt cable directly to the starter power cable, the starter worked fine (did this for 5 seconds), negative terminal did not get warm. I assumed then that problem might be with starter relay(mounted on fire wall) or the ignition switch. I replaced both, still have the same sympton. I cleaned the batt negative cable ground (batt is mounted in the trunk), still fails. I disconnected the power cable to the alternator as well, still fails. I'm out of ideas any and all suggestions would be appreciated, thanks.
