Quoted from JKnPA:
But relay#3 doesn't close until the Search index coil is
energized....... Yes or No ?
No, - the relay #3 closes which powers the search index.
Basically, the game has to check to see if you've already scored, assuming that it sees a winner. If you've cleaned the search disc and the arms (words fail me - there's a better name for those) - then you've got something wrong with the initial check.
The game still should have voltage on the appropriate rivets (you can check this in your manual and test them if you wish to see when balls are in the right holes), but if the score disc has, for example, a NO switch that isn't closing all the way or vice-versa on first step, then you will not score in that color.
Alternatively, if the game has a broken feeder wire to the spider units on the green score disc or the green replay counter disc, you will not earn replays correctly.
If there's dirt on either of those discs, then you may not earn replays correctly. Similarly if there's continuity problems.
I guess the question is - is it only in green? Reading back through, I realize I made an assumption. Does it ever score properly? Does it always score properly in other colors? That's where I was helping to troubleshoot.
If you're getting intermittent or improper scoring in all colors, you've already troubleshot 2/3 of the circuit. Your search relays (esp. #3) need to be reviewed - check for broken resistors and inspect gap of switches. Your search index relay has a small stack of switches that require VERY fine adjustment to work properly. -If- nothing is scoring properly, please observe the search index for minute pulses as the search disc turns. If it never happens at all, then your problem is likely in the search relays. If it does happen, then your problem is in the cleaning or adjustment of that switch stack.
Hope that's not too much info. Trying to start small and get bigger.
