Turn signal problem

1969 MGB Tourer. Turn signals stopped working over the winter. I traced the problem to the switch; the car cover had leaked and the contacts were corroded. I cleaned the contacts and the signals worked.
Two days later, no turn signals. I assumed (possibly erroneously) that the switch was shot. Bought a new switch from Moss and installed it: still no turn signals. In the neutral position (not signalling) there's voltage on the wiper (the light green wire). In the signalling position, the voltage goes to zero, as if it were shorted to ground. But the fuse doesn't blow, so that's not it.
Thanks for any suggestion.


To get a response I would suggest putting your contact info in the question.  No one will be able to contact you as the id of 2022 is used by many members not just you.

I would also suggest a name so that we can match you up with any responses we may get.

For a faster response, I would suggest posting on our Facebook group at:
