1972 FJ55
SBC 350
3 wire GM type alternator with only a wire from the Batt post to the + post on the battery
The other day after work, my rig was dead, hardly any juice in the battery. I thought it was strange, so I had some buddies push start me and I was off. After driving for an hour, I stopped, and when I tried to start her up, it was dead again. I pushed started it and home I went. On the way, my lights dimmed, turn signals and brake lights stopped working.
I pulled the alternator and it bench tested ok at 2 different places. I put in the battery from my FJ40 and tried it out. After driving for a while, my lights dimmed, signals stopped working, wipers slow.
I figured maybe some weird thing is up with the alternator so I bought a new one. Now when I run it, my voltmeter (aftermarket gauges) shows just under 13V and if I run the headlights and turn signals, the volts drop to under 12V. Is this Normal? Any ideas on what is up? Thanks for any help.
