Re: Mercruiser 3.0 L Ignition Conversion
This is on the positive side... one will come from the starter and will provide a full twelve volts while cranking. You want to keep that one and discard the other. You may need an ohm meter to trace the wires and see which is which. Did you look at the wiring diagram as mentioned above? I believe the colors will be purple, and the other purple with a yellow stripe. The purple with yellow stripe is the wire from the starter - that's the one to keep. The solid purple is the resistance wire.
