Alternator Replacement

[mvpacificrose]

My attempt to upgrade my system to Balmer's was a failure do to mainly the high cost. So now I'm going down the path of installing new DELCO MARINE ALTERNATOR CRUSADER OMC 1981-1987 ONE WIRE HOOK-UP 105 AMP and upgrading the wiring.

The issue I'm having is what to do with the yellow wire coming from the boat to the alternator? The previous alternator had a clip plug, but as the name implies...the 1 wire alternator only has the output terminal.

Where do I connect the yellow wire coming from the boat?

1988 Carver 3807, 454 Crusader's

Thanks,

Try checking voltage on that yellow wire with ignition Off and On (not in start). If it only has power with ignition in On position C
chances are that's an Energize/Field wire that was needed by the original Alt. You should be able to just cap and secure it with the new Alt because they are self energizing and regulated.
