Title: What is that ceramic block between the hot wire of the coil and ignition ???
Post by: 79charger on July 01, 2009, 05:27:46 PM: It broke , anybody know where i can get one for a bbf. Thanks

NAPA has them...

this is just for reference, try your local parts house im sure they have them ;)

No, if you change to a non-resistor type coil, or go electronic ignition.

Which coil is that? I bought a Mallory coil that wasn't suppose to need a resistor and it fried. That reminds me, I need to send that back for replacement.

It's called an internally resisted coil and if you use an internally resisted coil with a ballast resistor, if it will start it will burn up due to the additional heat generated...
