I bought this project, and am looking it over.

This pwm board is way too complicated for what it's doing; I'm going to look into making this also a pic programming project.

I also want a 100A PWM controller for my M8 fan, so... multipurpose use is in order.

BTW, here's a link to the OG article from P71; I hope it's with permission.

My idea is:

The GEN-MON signal is an output of what the alt it doing; that needs to be read, compared with temperature, and then a proper output duty cycle should be output to the Alt on the GEN-COM line.

The connector for this Alt is the WPT-118, which also happens to be the same as the TPS sensor. Most of us have a spare harness laying around, so the $40 pigtail isn't required. It's low current, so don't worry about these.

Repeated output high current pulses should trigger a "hardcore" mode, where it bumps it up a bit, and monitors over a longer period before adjusting; I've had amps fool a regulator before, to the point the battery slowly discharged... Vavg is less than Vrms.

I think a battery temperature monitor input would be a cool feature.

A WFO mode might be nice for the guys who need full output; although, if your amps aren't pulling that much, your battery is going to boil and explode, lol. The temperature monitor could help that.
And you need like ~2500 rpm minimum to get full current. And a bigger radiator and fan, lol.
This now reads more like a self destruct switch for noobs, lol.

Anyone else have any ideas on a controller for a charging system?

That makes sense to me, Grog.
