Re: (Question) HEI Internal to external Coil Conversion
Double check that you actually have:
- GROUNDED the tach case. A lot of people miss this. It does not ground through the cluster.
- Verify 12V at the (+) terminal of the tach
Then worry about the signal. But verify the ground for sure, since it's such a common cause of problem.
