Had to troubleshoot my non-charging issue with my 122. Ended up re-wiring most of the tractor while I had it apart.

Yes, all the wires are the same color, which isn't perfectly ideal, but I had the wiring on hand already so stuck to this as a free upgrade.

Jury is still out on if my charging issue is fixed... not been able to go back out to check on it since re-wiring it. Maybe tonight... My luck, it'll be the voltage regulator.
