1 wire internal or external oem alternator

72blunblu,

You make a good point on amperage demands vs alternator capability. With my Duster I run mechanical fan, mechanical fuel pump, no AC, no radio, and a points distributor (after frying a Pertronix module while trouble shooting wiring with the key on). So my electrical demand is minimal. The reason I went to points after frying a Pertronix was simply the fact I fried the Pertronix. Yes Pertronix makes newer units that are fry protected unlike what was on the car, and yes I now know I should have disconnected that module. But I can’t fix that on the side of the road to get home and point can be fixed and are cheap to stock in glovebox if I ever do it lol.

But anyway, I forget some have fallen in love with electronically controlled cars and accessories. I am going backwards because it’s too complex in many ways, especially a road side repair.
