Ghost in Passenger side Blinker

Welcome to the Board, photoer!

Sounds like a ground problem. Don't assume that what looks like a good ground is a good ground. Ground screw connections are notorious for causing all sorts of electrical issues. They must be clean and tight!

If you send me a private message with your email address, I'll send you the wiring diagram.

You have a double earth fault.

Thanks Keith - not really familiar with the term "double earth fault". Grounding points for the light circuits are feindishly difficult to locate on the 74 Alfa Spider. (am I missing something?) On top of my mentioned woes, I have no current going to the high beam on the passenger side. It has to be a simple problem to solve but I fear that the steering column lever cluster might be the culprit. I would like to solve it by logic alone. Pleas advise re. "double earth fault". Many thanks. Erik

double earth fault = two ground problems

There are four headlight fuses; one each for left and right high & lowbeams. If the left highbeam works, then the headlight switch is not at fault as the left and right circuits are split in the fusebox after the headlight switch. I'd check/clean/replace all fuses as necessary first. Then check for battery voltage and ground at the headlight connector.

Headlight grounds are favourite, disconnect circuits at fuse box & test each ground (earth) with an ohm meter. You indicator/ running lights also have a ground fault. Current fails to travel round one circuit & then finds the shortest path. i.e. another cct.

Thanks for all your advice fellas. Much appreciated. I have fierce brush fire and then some issues at the moment (living next to Malibu). When the - ehm - dust settles, I will delve into my Alfa wiring again. Will report asap. E
