Star Trek: The Next Generation
Williams, 1993Game was working fine. Then drop target and under playfield divertors stopped working.
In test, none of the solenoids 37-40 work (drop target up and down, under divertor top and bottom). All other solenoids work.
I can't find any fuse associated with these solenoids in the manual.
Any idea where to look?
Thanks,
Dave
That fuse is blown. Replaced with a good fuse and it blew immediately.
Sounds like a short? What to look for?
Quoted from dmesserly:Sounds like a short? What to look for?
Check Q13 - Q16 on the driver board by measuring the resistance from the metal tab to ground, low resistance means its locked on. You could also have a broken tieback wire, this can case major problems with this circuit, this is a small purple/green wire attached to the drop target.
I have had a couple issues with my subway diverter and Pin Guy was good enough to assist the last time and help me (thanks Pin_Guy) I had a blown transistor on the aux driver board that had gone south. Replaced that, related fuse verified that the tieback was still in tact which it was and all was fine in STTNG land once again. If your diverter coils are not working, I would be willing to bet that one of those transistors that Pin_Guy referred to is toast. Easy to replace. Good luck.
