Oliver 60 wiring diagram

1. With switch on and well charged battery, you should see near battery voltage at input to coil

2 At output of coil you should see near battery voltage with points open and near zero volts with points closed.

After sitting for a time it is not unusual for points to develop a film on the metal surfaces that insulates them from making contact. I use a folded dollar bill and wipe it through closed points. If that does not clear the film, I use a piece of heavy paper like a grocery sack and moisten it with contact cleaner.

There could be other problems with old wires or corroded connections, but I would first make sure points circuit is working.

Thanks.
