It doesn't just keep the belt tight. Surely it charges the battery through the regulator. No ? So if a 6v 40A gen produces half the amperage in a 12v system it must be producing 20A. And the 12v gen produced by Autolite produced 25A. That's not so far off.Wolfman wrote: ↑Wed May 16, 2018 3:54 amThe output from a 6 volt generator is most likely not going to get high enough to close the contacts on the cut out relay or activate the electronics in the 12 volt regulator so the generator is never actually connected to the 12 volt battery. It just keeps the fan belt tight.
In your jeep, you need something that keeps the battery charged. 6 or 12 volt.
Also I imagine that the gen is producing current all the time and it's the regulator that cuts off the current if the battery is charged. So I don't think the gen will cook itself.
I've ordered a good battery so I will fix it up next week if I can find the time and see what the voltage level across the battery/gen is.
Plan B - the alternator...
Wish I'd paid more attention to this at school !
