I'm working on a:

1958 Chevy 235
12 volt coil with internal resistor
Pertronix kit in the distributor

I just installed the engine. I wired the engine to the battery and I am running a jumper from the battery to the coil (all wires are stripped out of the car, new wiring kit to be installed soon). I got a spark on the first try, but now I am not getting any spark at the plugs. Everything is new. I pulled the pertronix kit and re-installed the points, still no spark. An Ideas?

Could the pertronix kit make the coil go bad?

Is there a way to test the coil?

Is there a way to test the pertronix kit?

Should I only be using a coil and an external resistor?

thanks
