Porsche tachometer

Hi SilverBullet,

If i'm not wrong, you are from Singapore right? Are you still facing the problem? I installed mine and it works just fine. I think I connected to a '1' on the ignition coil.

Regards,

Hi

I had an old Stewart Warner tacho that originally only used - from the coil and an earth, when I had it converted to run with electronic igntion and EFI it would do the same thing on shutdown. I imagine its caused by backfeed.
