Firstly, I'm not sure my wiring is correct, so I just want to quickly confirm. I have three black wires connected to one terminal of the capacitor: - one grounded to the chassis - one from terminal 5 of the transformer - one to pin 3 of the J8 connector I also have two red wires connected to the other terminal of the capacitor: - one to pin 2 of J8 connector - one to pin 4 of J8 connector Is this correct???
