The old style system works fine. Back in the day, we rebuilt 2-3 alt's a DAY. Techs would change brushes, bridge, bushings, and diode trio(bet not many know what that is). Fairly cheap if you could do it yourself. Then there's those darn remote reg's. Sold alot of them also.
The newer style works better. At 1st they had issues. Now we maybe sell 1 a month. Cost more, but anyone can R&I one.
