I'm down to the last (I hope) major issue on my Freddy project. The glove flipper isn't working. This is a little challenging to troubleshoot. There is no flipper test in solenoid test, and the glove flipper only works when a relay is activated. The good news is, this is a simple flipper system and I'm totally stumped as to why it isn't working. Glove Flipper relay works in diagnostics. Pressing the relay manually gets me voltage on all 3 lugs, 62v (the other coils are getting 66). Grounding the non banded side of the other flippers activates the coil. Grounding the non banded side of the glove flipper does nothing. This was done while holding in the relay, there is voltage at the coil. The coil is brand new from PBR. I'm getting 4.5 ohms across the outside lugs. I'm getting 5.2 on the right flipper coil, and 16 ohms on the left flipper coil. This is clearly odd. Lower flippers work fine, and I think they are both new coils as well. Any ideas? I suppose I could swap the glove flipper coil to a known working setup, but I'm confident the coil is fine.

Sunday bump! About to dive back into this thing. I know I'm missing something stupid.

Been many, many years since I fooled with a Freddy, but aren't the flips allowed on the glove limited? Just thinking out loud here...

Yes, they are very limited, which makes troubleshooting a nightmare. I swapped in a known working coil and nothing changes. The new coil was fine.

Glove flipper works! It was either the Q relay or the glove flipper relay that was dirty. I'm pretty sure it was the Q relay.
