Bosch pencil coil pinouts?

Postby david@dtmpower.com on Fri Apr 23, 2010 7:42 pm

Does anyone have any info on the connections to the Bosch pencil type of coil. The Bosch # is 0221 504 100 or 464. there are three male pins in a triangle inside a radiused triangular housing.
Thanks
David

I saw this a little late, but...

coil on the vertical position
- upper pin = secondary ground
- lower left pin = +12V
- lower right pin = coil -

And this is a curve of primary current / Dwell-time at 14V (RED curve / right scale).
Upper curves are different Dwell-time secondary currents.
