GT electrical issue

Evening everyone,

I was wondering if anyone has any ideas on this.

On starting my GT, when I put the dipped beams on, the instrument cluster illumination sometimes goes out. Or flickers on and off. When this happens, if I switch the main beams on, the dipped headlights and the instrument cluster lights will flicker on and off constantly. It doesn’t seem to have any effect when I only put the side lights on.

Also, when the instrument cluster lights go out, the hazard and fog lights won’t turn on either. Oddly enough, after a few minutes of driving it settles down fine and everything works well.

Any ideas? Crazy Alfa electrics!

And I should add that the lights work ok, even when the instrument illumination is out. I’ve also checked the fuses and relays and everything is fine.

Hi Mossy,

As the stalk switches likely send a CANBUS signal to a body computer of some kind, I'd suspect wiring/connectors to this computer, or a faulty computer.

I'm not sure where this is on our car (have only had mine a week!) but on my old Fiat it was located behind or part of the fuse box under the dash.

Maybe someone else can chime in if there's an engine-bay multi-connector (like Fiats D4) that is often the problem?

I'd first check the simple and obvious, since the symptoms suggest a bad connection that is going high-resistance when loaded. So: are battery terminals clean and tight? After that, the positive connector has distribution links that can corrode and crack. If in doubt, dismantle, clean and check.
