I can stand corrected but I believe there needs to be a resistor installed for those if not is it a hei? If so check the batt wire make sure it on the ignition side not on a constant feed

Some alternators need to have a diode to keep back feeding or be hooked into their own leg of the ignition switch to work correctly.

Most auto parts stores should have diodes available for this.

The boat ran 2 days prior to this just pulled the motor and put it back do yo think something in the alternator broke would the quick fix be to just add a diode

You probably have a wire connected to the wrong spot on the terminal bar.

How many wires on your alt? Large gauge charge plus 1 or 2 small?
