OK, so I think you're saying that the turn signals used to sorta work with this 7 pin switch. But now they don't work on either side. Do I have that correct?
It would be simpler if the turn signals worked fine pre- 7 pin switch and not at all post. But it doesn't sound like that's the case. Right?
The turn signal current passes through the emergency flasher switch; if the switch is disconnected, your turn signals won't work at all. If you make a short jumper wire with male terminals at both ends, and use it to connect pins #30 and 49 on the e-flasher switch connector (obviously with the connector detached from switch itself), the turn signals should work without the e-flasher switch connected. It would be interesting to know how things work with that hack in place.
For extra credit, you could check the switch for continuity between its pins #30 and 49 with the button in (should be connected) and out (should be disconnected).
Replaced it with what? And did the replacement flasher make the problem better or worse? What happens when you put the old flasher back in?
e9's (and e3's and 2002's) are very sensitive to what type of flasher is installed; flashers will only work if they trigger with exactly the right amount of current. Substituting an electronic flasher is the simple solution for this problem.
