no, bad. you need to keep the black wire in the harness. it is the engine ground, which connects the coil to the head. if you have a mis in one cyk, it will kill the other as well. you should have floated the ground in the stator and ran that to the rectifier allong with the normal output. it would be an added wire, so the black wie can stay stock, where it grounds in the loom clip. from there, you plug the outputs of the regulator/rectifier into the stock system, minus the stock regulator. your rectifier probably has 2 outputs. one for battery, and one for feed, then a shared ground. if not, i suggest using the brown and red wires in the keyswitch to feed the battery, or a relay, or install a switch somewhere.
