Hi Ed,

What circuit are you using to drive your Accel Super coil? I have an Accel
Super 50KV CDI coil. Maybe we can compare notes.

Thanks,
Jim Mora"

   Driving it from 12 V using an HV NPN power transistor in turn 
driven by a 555 timer and buffer - nothing special at all - pulse 
width adjustable "for maximum good" and pulse rate for allowable 
battery current; transistor doesn't get very warm.  I may even have 
changed the transistor to an IXYS IGBT but think that is another 
driver.  I'll have to figure out what coil I'm using - got it at a 
Hot Rod shop and it's not a CDI type. If I called it an Exel that's 
because I was working with an Excel spread sheet at the time - it's 
an Accel for sure.  I haven't touched the coil or driver in several 
years and would have to try to dig up the schematic (too lazy to trace it).
