Defective Ignition Coil?

[JRGBoss]

Recently the alternator, regulator and solenoid, coil was replaced on the 68 RT. Starts right up when cold but when you drive it for a while and turn it off it will not start. The ignition coil feels hot to the touch, once things start to cool down the car will once again start right up. Could the ignition coil be defective?

Could be a few things,

What happens when you try to start it? Does it crank? Hows your timing?

Could be your starter solenoid getting heat soaked, could be you have your timing a bit too advanced and theres simply not enough grunt to get it turned over hot. Just need a few more pieces of info

It cranks fine, just wont start until things cool down a bit.

Just curious is your ballast resistor bypassed and what brand coil you using

Supposedly what was causing it was too wide a gap on the points. Not sure it was related but the alternator was not charging property so it was replaced, again.

Id change my points to pertronix and use their coil which eliminates the ballast  .As points distributors get shaft play and cause erratic timing

I think you are right. I am in the process of rebuilding my B2 motor and installing the petronix in the distributor. Thereby eliminating the dual points.

The Pertronix are great, I've had it in my car for 7 years now. The instructions state to leave the ballast in line. Will it fry the coil if the ballast is by-passed?

In think if you use petronix coil you can hardwire the ballast from the back for stock looks

Depends on the type of coil you are using...There's ones with an internal "Built in" resistor and regualr coils without...The STOCK coil needs the resistor..

However, you upgrade to say an MSD unit, most times, they do not need the resistor...(Full electronic ignition, and not MSD on point type ignition)

I used the Pertronix Blaster coil. I made a jumper yesterday and drove the car for 20 miles or so. I did notice a difference. It enhanced a top end stutter/bog thing I'm chasing.
