You may need to use an LED light bulb to get this to work ...

Had this happen a couple times before. It is typically a bad ignition switch...but just for the heck of it...do you have both the 'R' and 'S' starter solenoid terminals hooked up?

This is what I've read as the most common culprit as well.... I've got the R and S wires on the right terminals, but will def check again!

Thanks all, I'm going to get a stock points dizzy, another new coil, and will try to find another ignition switch - not sure how to change that, but I'll figure it out!! If this was easy, everybody be'd doing it!

Marlin,

Its not the key switch you want to change its the switch assembly on top of the steering column. The key assembly when in the run position and cranking moves a rod that actuates the ignition switch assembly contacts. Drop the column down unplug the connectors, 2 5/16 bolts, remove and replace, pretty straight forward.

if you have a spare steering column around maybe rob one off that if they are the same. I'd check these connectors also maybe you have a bad connection?
