Greetings, all! This is a newbie question for a Stern Star Trek Pro...
So, I bought this a few weeks ago, and on arrival, switches 11 and 21 were out of service. (11 was center drop-target, 21 was R ball trough.) Each had an IDC connector that had a wire that had unseated and was loose..
On the sage advice of others here, I bought a wire-insertion tool, which did the trick for switch 11. For switch 21, there was a piece of old wire stuck in the connector, so I took a new IDC connector, inserted the white/green (loose) wire in the same position (triple-checked), snipped the middle green/red wire from the old connector and inserted it into the new, and then followed suit with the final white/blue wire.
Switch 21 now back in service, but now switch 22 is out of service. 22 is ball jam switch.
My first thought was that I didn't insert wires well enough, but I checked, and I'm pretty sure I did...?
Then I thought that, perhaps, I switched the orders of the wires, so instead of 21 being detected as dead, 22 is instead... But I did a pinball trough test, and switch 21 IS detecting the ball in first position.
. If I had switched the wires, and the trough test thinks 22 is actually 21, why would the switch condition show a pinball in position one (result for 21) if there's no ball jam (condition for 22)? (Am I thinking this through correctly?)
The switch test shows that the wires for 21 are white/green and green/red.
Switch 22 shows as white/blue and green/red, so I'm pretty sure these are all to the same connector.
The IDC leads to a male/male adapter. The white/blue IDC 22 wire carries over into the white/purple wire which is seated nicely...
...and leads to an opto attached to the ball trough.
Did I do something wrong in repairing switch 21 that led to a malfunction in switch 22? It wasn't reading as out-of-service until this happened...
