Hi
I recently bought a norton commando 1971 in parts. The electrical system seems to be modified, does not match the wiring diagram for this model. How can you find out if it is + or - earth? Most of the wiring is disconnected.
Wondering also if anyone is familiar with this:
Lucas O.P.U.S Ignition
Amplifier unit
AB5 type.
12V Neg. Earth
Is it the same as Rita AB5? Does the Rita also have negative earth?
