Hello,

I was just wondering if someone could explain to me how this alternator works? There are 3 wires: 2 red wires on their own separate B+ terminals but go to the same starter terminal and one blue wire on a D+ terminal that goes to the charge lamp. There is also what appears to be another B+ terminal but no wire attached to it.

1) Which wire would regulate output?

2) What application would the other B+ terminal be used for?

Thanks again,

Marc-Andre

AL80X has internal voltage regulator. There is no need for external wire. Additional B+ terminal is for noise suppression capacitor. Part 001 156 69 01.

Thank you for the info. Is the noise suppressor necessary?

It is there to keep alternator whine from nearby radios.
