I'm working on a Space Station, and it began blowing fuse F4 on the Aux Driver board. Installed was a 2 Amp Slow Blow fuse. I've checked the resistance on all of the coils that F4 is associated with - If I'm reading the manual correctly, they are Solenoids 3A, 4A, 6A, 7A, 13, 17, 18, & 20. The coils seemed to read around 8 - 15 ohms each, so I don't think they are bad.
One of the things throwing me are the transistors associated with the solenoids - I can't seem to locate them. I feel like a novice! So where are the driver transistors located? I don't see them on the aux driver board - Am I overlooking them? Thanks
