[Mgs] MGB Turn Signals

[Max Heim]

My switch was a “replacement” as well, although it was at least ten years old when the problem occurred. I spent a lot of time monkeying with it before deciding to just buy a new one. Then I attempted a post-mortem, and discovered the missing spring. I think I probably could have fixed it, assuming I could find a suitable spring. It might have involved drilling out rivets.

If you wanted to try it, I would check to see if I still have the switch I took off — you could have it for parts.

Basically, I determined the fault by jumping the contacts with the key on, and seeing what resulted. I could make it flash with a jumper, but not with the switch.

When I just had this same symptom, it was because one out of two springs under the floating contact had vanished, so it would not make solid contact when at one end of the stalk travel, although it was OK at the other end. Result: turn signal flashed only on one side.

I have replaced the bulbs in the front and rear turn signals on the right side, and checked to see that all of the fuses are OK, but still no turn signals on the right side.  Any ideas?
