Default G2 not charging battery

I cannot find a year on the frame, but I believe itís a G2. Iíve replaced the starter generator, voltage regulator, and solenoid. The battery has been load tested. Iíve been trying to figure out why the system will not charge the 12v battery for months. Iíve unhooked all accessories. Iíve taken the green wire from the generator and grounded it. The voltage actually drops to 11v when I did that. Iíve also noticed that the red wire that connects to the A2 on the generator gets red hot when driving. What else could it be? Thanks!

When you ground the field wire on the starter/gen it should go ďfull outĒ and that is generally somewhere around 17v or so

If this isnít happening then double check all your connections and make sure the engine/cradle/starter gen has a good ground connection. These are notorious for bad engine grounds. You should have less than about 3 ohms from the engine (anything metal) to the negative battery terminal.

If all is good and it still doesnít increase voltage when you ground the field wire itís a bad starter/gen. What kind did you get? Oem or aftermarket?

I just checked the ohms, and Iím getting between .8 - 1 ohms. The generator is after market, but I swapped it with a new OEM from different working cart and it still does the same.

The red wire on A2 or any other terminal should not get that hot. Have to solve that problem first. Usually a poor connection will cause it. What does the ring terminal look like ?

Iíd check the grounds with the engine running. Make sure when the circuit is loaded, that it maintains good contact. Do a voltage drop test on the power and ground sides of the system.

Iíd also go through all the wiring with a fine tooth comb. Something isnít right, but youíll have to do the leg work as itís hard to tell from 1000 miles away what youíre looking at.
