Hi

I just replaced the OEM alternator on my 67 Riviera.. bought a Powermaster 12si unit...and I'm having some issues..

I'm experiencing a backfeed, eliminating the keyed ignition-switch (aka can't turn of the ignition)..

1. Stock alternator wiring/plug is only a blue wire..NOT a blue and a white wire

2. Connector at the external regulator has 4 wires..

F : Blue wire (10 gauge)
2: Red wire (10 gauge)
3: Red wire ( 8 gauge)
4: Black wire (10 gauge)

Bought the American Autowire 27555 alt.conversion kit.. that did not help.. i know this kit basically bridges 2 wires..

What wires do i need to bridge,in order to NOT get a backfeed (eliminating the ignition switch)..

Please advice ?
