Ignition questions & the Nat semi Injector driver

[Fred Miranda]

Jim:
7-8yrs ago, before I knew too much about these things, I built an igniter box
for my rotary pickup in which I had installed a mag pickup dist.
I'm sure some will scoff at the simplicity of the output, but it did work
and never blew in several years of use.

I used a TIP152 400v 7.5 amp darlington. (and a balasted coil)
Thats it. The TIP152 has an internal clamp for reverse voltages
and I guess the transistor soaked up the positive spikes.
