Electrical- Batt Light/no Gauges

Neophyte at work. The battery light on the dash went on. No gauges, radio, tach, pilot lights, etc were working. (I had recharged the battery and it starts the car.) Assuming it was the alternator/voltage regulator I removed/replaced the alternator without checking it.

Started the car, same problem.. There was an intermittent period where the batt light went out and all was OK. But that ended (I think when I turned on the headlights but not sure).

All isn't working again. Is there some fuse or relay or whatever?? I've read the forums and it looks like the place to start is clean cables, fuses etc. Where would you start? Is there some "magic" fix, a relay or something that I'm unaware of?? Help. Tom

Welcome to the BB, Tom!

You didn't mention what type of Alfa you have... You could try to do a search in this forum, and also on the one specific for the model of your Alfa. This topic has been covered and discussed in several threads.

Best regards,

This is a really old post, so hopefully trcar has already solved it for himself. However, I just went through this and wanted to post my findings for posterity.

Same issue on my '86 spider...Either get the alternator warning light and dead gauges or live gauges with the alternator light off. "randomly" toggling between the two states. Turned out to be a loose fuse #8...tricky find because of the alternator light being on...(must be back-driven through the ECU?). Anyway, I bent the fuse-holder tangs towards each other and all is well for now. I plan to put a bit of surgical tubing (rubber band) around the fuse and holder to keep the tangs from relaxing back to their intermittent connection state.

You'll find that fix doesn't last all that long as the heat breaks down the elastic pretty quickly leaving you with the same problem plus bits of loose stuff to clean up at slightly longer intervals than you do now.

A much better plan in your case would be to aquire an 87 or later fusebox (I believe it's the same box up to 94, but to be safe, I'll say 87-89) which uses the modern type fuse in it, do the straight up exchange (remove wires one at a time from the original one, plug them in to the corresponding spot on the replacement, repeat til done) and never worry about that stuff again.
