If I buy another 1 wire alternator it will only get used on the run stand and then it’ll just get boxed up and lay on the shelf. I’m cheap. I already have 4 good working older alternators laying around. I need to run this engine on the run stand for a break-in. My trucks both have one wire alternators and I don’t feel like borrowing one from a running truck.
I have some voltage regulators laying around. Can I wire this alternator using one of them? Advice?
Oooooooooooooops! This post is wrong. Upon further looking I think that alternator is a 10DN. These were the earliest GM alternators, first used in 1962. They DID have external regulators.
Wrong stuff here. I'm having a hard time finding a Delco 5619 alternator internal diagram, but I'd bet the moderator's life that the alternator shown on your picture above has an internal regulator.
I'll keep looking.
Here is the 5619 from your picture.

A charging system on a run stand is totally unnecessary. Just run any sort of a generator or alternator as an idler to run the water pump, with no wires attached, and run a battery charger on the test stand battery to keep the voltage constant on the ignition system.
I don't even bother with a radiator or a water pump for a break-in run- - - - -just plumb a garden hose to the water pump inlet and let the warm water run out of the thermostat housing, without a stat installed. Control the engine temp by adjusting the volume of water the hose runs through the engine. Jerry

Excellent idea. I certainly can do that. I have a few voltage regulators in the drawer somewhere but this is easy. Thank you.
