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?
