HELP! Upgraded alternator in my '75 280z but headlights now won't work.

Heck, Dave. I wasn't going to give him any suggestions on the headlights until he sorted out his charging system.

Well, I figure it this way, kill of one problem at a time until there are no more. If he can find a simple solution to the headlights, that leaves only 1 issue remaining and easier to figure it out... But I totally understand where you're coming from SteveJ

I will start with the alternator first, as it will at least let me drive to and from work without being stranded! =)

Thank you all for your suggestions btw. Like I said, worst comes to worse, I'll just slap the 50amp alternator back on and live with it. I'm thinking there's some work-around for the missing wire- just got to wait for those who've worked around it to reply.

EDIT: I did test the fuse-able links and power is going through both. And in the diagram that zedhead had post http://atlanticz.ca/zclub/techtips/fusiblelinks/index.html

the two fuse-able links are for ignition and alternator: not for headlights. See? I'm learning.... i think

The path is not easy to trace, but the headlight circuit is protected by the black fusible link.

Gave in and re-installed the 50amp oem alternator. And voila, everything works normally, even the headlights. Odd....
