The coil for my son's Tao Tao GK110 suddenly went out. After checking voltage tolerances I determined the old coil was bad. I installed this coil, but had to change the position of the wires in the plug. This was easy to do with a bobby pin; stripped off the little plastic nub on the end of the bobby pin, and use the pin to unlatch the metal pins in the harness so you can pull them out and replace them in the correct order. The kart fired right up and runs like a scalded dog again.
