Ignition Coil Type????Blue, red, etc
 

Hello all,

Well, I ebayed the 220SEb to support the 6.3!

I am now trying to get the car running after many years of being dormant.

The car currently has a Crane Cams XR-700 optical ignition conversion, it is running an unresisted Bosch Red coil. I'm thinking this setup is wrong. The spark is there but is not the bright hot spark that I need.

Should this setup have a bosch blue coil to run unresisted? Would adding series resistors help the red coil produce a better spark? If so, what values of resistors should be used?

Thanks for any advice you have.

Happy Motoring, K.

Masure the coil resistance across pos/neg terminals and post the finding..

It's a few years old, but may still apply. The spark on my ignition system is not the bright hot spark I expect, but that may be what it was 40 years ago.
