Quoted from herbertbsharp:

Thanks! I tested the transistor according to pin wiki and it looks good, I think . I think everything is good between it and the solenoid too, so I guess it must be upstream from the TIP-102. I'm going to try breaking out the schematics book to see if I can follow it

Did you check the switch that tells the solenoid to fire? It could just be that the switch is bad...

What coil is the problem?

Quoted from ForceFlow:

In test mode, you can just fire the coil from the menus.

Right, I forgot he said it didn't fire in coil test. That would eliminate the switch.

Knowing what coil it was would help...

Thank you, I'll look at that one. I'm thinking you are probably right.. ughh... chips... I knew I'd have to do one sooner or later.

If you replace the chip, socket it. Probably won't be the last time it needs replacement.
