I get that, I just don't understand why it's doing the opposite in mine. I tested it again after drive and I'm getting 13.8 at alternator and 12.7 at bat seems like some resistance going on as well.

It used to stay on. I rewired from after the fuse link straight back to battery opposed from the birds nest it was. Now its off when not running and when you start it it stays off until idle down from choke opening then it comes on and starts charging... I don't fuckin know man but at least it is charging now lol.

Ok I've found that it doesn't charge until the choke shuts off. When it does its charging great I can unhook the battery and all now but as soon as it starts charging the light come on

Choke shut off and now light is back on... What the heck is happening lol

I made my own connection straight to the battery. My charging light is now not on but still no charge?

Ok I've traced down the wire through the links and up to a mess of wires from previous owner. The there were maybe 3 wire strands holding onto the crimp connection to the battery cable. I checked voltage and getting like 300v from the wire that needs to go to the battery! That cant be right?

And shouldn't I still be getting higher than 11.3 at the alt itself?

Where is this link?

Yes and yes

Soooo, I just bought my 3rd 720 all 85 2wd and this one is a wiring disaster! Alt is testing good on bench but only putting out 11.3 on the truck? Battery is new and good. Is there a chance these have a on/off from ign. To alt.? If so what do I need to check for? Thanks
