Hey everyone - when i purchased my 1978 Columbia Commuter, the previous owner stated that it needed a new coil to start up. It had the original coil - black with a positive and ground (i think - according to the wiring diagrams i've seen) terminal (low circuit) and then the out of the high circuit leading to the plug. The new one i purchased doesn't have a ground terminal, just a positive and the high end to the plug.
Am i right in assuming the ground isn't necessary as it's grounded by the mounting?
Later this weekend i'll do some testing with a volt/ohm meter, but for now i thought i'd just ask.
