Adjust output of dynamo on 1929/30 commander

[bifda]

I have a 1930 GJ Commander and the ammeter always only shows a low output even when the battery is low, it had a Delco dynamo. My 1928 Dictator always shows a high output. A few days ago I drove the commander in the dark for about 45 minutes with the lights on, upon stopping the engine it would not crank as the battery was dead. It has a fairly new battery on the vehicle and has never charged greatly. Is there a way of adjusting the regulator so as to increase the current it is feeding back in to the battery.

As an aside I also have a 1926 Studebaker with a Wagner dynamo, that has a new regulator on top, this is not charging at all, I seem to recall that when a new regulator is installed it may need to be given a kick to get it working, is this correct and if so how do I do it

Thanks

You should learn how to use the search function of this forum.

If you scroll to the top yu will see a white box with a magnifying glass next to it.

Enter polarizing generator (your dynamo).

You will find many posts regarding this and find one for your car.

Older cars mostly used cutouts instead of regulators and some generators used a third brush to adjust the voltage.

I am not familiar with generators from that era.
