no spark after reinstall

Post by tewbert »

I have ver 2.2, with msII and msd ignition. The car was running fine and I removed the megasquirt to configure it for bluetooth. When I reinstalled the squirt, the ignition was on for some reason. Now I have no ignition at all, no spark to the coil. Could I have fried something plugging in the squirt to a live harness? I've checked all fuses, including the ones in the relay box. I'm not using the bluetooth either, still using the computer cable. Any ideas mucho appreciated. :(

What circuit are you using to drive the MSD?

That would be the input... what about the output circuit?

Oops. Peter Florance repaired this one other time for me and I believe he used something more beefy that the transistor listed in the manual. Not exactly sure though.

I'm gonna fire this thing off to Peter and let him check it all out. I'm out of town for a week or so and won't be able to do anything with it. I'll let you know the results.
