MG MGA - FLASHER PROBLEM

Right turn,the front and rear FLASHER work perfectly. LEFT TURN all four,front right and front left along with both right and left rear flash together.

Any ideas what is wrong???????

Mine would do exactly that along with some other weirdness before I tore it apart for restoration. I didn't really do any troubleshooting since I am replacing the harness anyway, and I removed the old one mostly using wire cutters. Do you have a 1500 or a 1600? I think it might have been at least partly due to issues with my 1500 turn signal relay, but some of the wiring and connectors were in really poor condition as well, so it's also possible that contact was being made elsewhere where it shouldn't have been. If your car has the relay, that may be a good place to start.

Error in wiring at the turn signal relay. See here:

Pat attention to the wire colors.

Barney, FWIW I am reasonably certain that nobody had messed with the wiring at the relay on mine in decades, maybe not since new. I'm kind of curious now what had deteriorated to cause the problem, but at the time there hadn't seemed to be much point in chasing it down.

Come to think of it, my "new" harness was purchased by my dad in the late 80s, so I am going to have to look it over with a fairly critical eye before installing it. 8^/

Did a complete relay check,as per Mr. Gaylord and things are all right. But within a week I am back with the same problem.

Intermittent problems are a bitch. You have to diagnose it while it is in the failure mode.

Check all earthing points at all corners, being more attentive on the LH corners

And the winner is Domenic. It was the ground wire in side the grill area. I had to take out the grill to get to it . THANK YOU DOMENIC.

Classic symptoms, easy diagnosis, I am just surprised to be the first to suggest it. Happy it was easy to fix once you knew what to look for
