TaoTao Thunder 50, replaced stator, regulator/rectifier, still charging at the battery 16+ volts DC. Swapped r/r with another scooter, same thing, other scooter charging normally with original r/r and with the one from the problem scooter. Some people point to a ground issue. The green wire that attaches to the front of the engine, where are the other ground points? Also others say the connector at the r/r maybe bad, how to test that? This is making me FKing crazy. Please help.
