Alternator exciter

[ruschman]

I am now using an exciter button on the alternator. If I replace it with a 3 watt bulb on the same wire will that work along with the jumper wire fron #2 to main charging post.

An incandescent bulb in place of the button should work to send excitation power to, the #1 spade. The bulb will light when the alternator is not charging and go out when charging starts. A wire from the #2 spade to the output post provides system condition sensing feedback to the regulator and should be installed in either case, button or lamp.

On it. Thank you very much.

Make sure you power the lamp from a switched power source, such as the ignition switch, so it does not have power when the engine is not running.

I haven't looked, but isn't that where the button is wired in at present?
