Need help with my zz502

[drdave69]

I finally got around to checking the starting voltage. I pulled off the input voltage wire from the HEI and checked the voltage with key on. It is 11.8 v. In start mode it goes to 9.8 v. It is the same when the engine is up to operating temp. The next thing I am gonna check is the voltage when running but that involves removing the cap from the coil.

I also drove it about 10 miles and it also has a miss. Got to be something wrong with the ignition but I haven't figured it out yet.
