69 Charger electrical problem

[Roscoe P Coltrane]

I have a 1969 Dodge Charger and I replaced the alternator and voltage regulator and it was charging fine. The other night as I was backing it into the garage the lights went dime and the ammeter showed that it wasn't cahrging. I have checked everything I can think of and I can't find the problem. Any ideas on what the priblem might be would be appreciated. Thanks......

Some of the older dodges had a fuse wire in the voltage regulator.
Is the alternator getting 12 volts from ign switch /regulator
Get a good wiring diagram of your alternator charging circuit and check things over.

Thank you for the ideas. I couldn't find a fused wire in the system and I haven't had a chance to check the voltages at the alternator. There is also what looks like a relay of some kind located on the drivers side firewall right below the main whip plug-in. It has a fuseable link that runs into the main plug in and a red wire that runs to the battery with a couple other wires connected to it. I'm going to change that next and see what happens. I'll post my results once I get that done. Thanks again....

Ok.
On the voltage regulator fuse wire I think you have to pull the cover of regulator to get to it.\
Been long ago but I cut my teeth on them old 60 mopars.

OK....after many hours of pulling out what little hair I have left I decided to check the obvious which I should have done from the beginning. The "new" alternator I bought from NAPA had a field short in it and wasn't working. I thought it was working because under high idle it showed charge...both on the ammeter and on a battery tester so I looked at everything BUT the alternator. Finally I got a bug up my posterior and tested the alternator itself and found that it WAS the problem lol I guess I'll start with the obvious from now on and work my way back from there. Thanks for the suggestions and ideas....

You are welcome and.
Thanks for posting back the fix and we are glad you got it going good.
10-4 on the basics. If all else fails basics and proper testing will do it ever time.
I remember when the alternators first came out on cars.
The old timers all said they were no good and would not last.
They sure hated to give up the old generators.
Good luck MT
