Is this still voltage regulated like a cars alternator would be? What is the charging voltage?

The regulator I had on the shelf has a cutoff at 14.2 volts. A bit high for my tastes.

But, if the rest of the cobbling holds, it'll beat the heck out of running a 2KW genset for hours on end. Or carrying enough battery for 5 days of camping.

Since I am keeping some old (1980's to 1960's) equipment running, I keep a Chinese copy of the Chrysler 2-wire electronic regulator on hand.

The GM 1-wire is all well and good, but has a 50ma drain when 'off' plus the regulators blow after about 100 operating hours. It takes a couple of hours to rip out the internal regulator and rewire the tractor (again) for the external regulator located much farther away from the exhaust pipe.

There are several web sites selling an adapter plate to run a GM 1-wire off a lawn mower engine. I just had to do it myself!
