Quoted from currieddog:Question remains: what is the tie in between the special reel reset and the ball draining and play continuing correctly? Oi
I believe it is the Score Motor being able to run. You didn't respond to my question of what happens if you give the score motor a push to run a cycle (after you have placed the ball in the outhole)?
The Page I attached named FF Spcl Reel Rst RE shows the path that apparently IS working since it only comes into play when there is NOT zero on the Special Reel (kick out hole advances swing reel from 0 to 1).
So, it appears to be the fact that the score motor is not getting turned on by something that can turn it on (limited number of switches shown at 4/5-C on the schematic that can do that). With what's there, obviously the Outhole Relay is the one that should be turning the score motor on. So, we need to look at why the Outhole Relay isn't being allowed to turn on by the Ball Trough Relay or other function that occurs when the ball trough relay is energized.
When Ball Trough is made, there are two paths at 15-C depending on the state of Ball Index. When no score has been hit, the Ball index is de-energized and the path is to the Outhole relay (though a break switch on the Cent. Target Re.) Apparently, this path works correctly. The Second path is when the Index Relay is energized (Something has been scored), this path, goes through a Break Switch on the Bonus Relay (bonus is not energized according to you) and goes directly to the Center Target Relay. Which, when you say you either hit the center target or manually energize the Center Target Relay, it serves the ball because this makes the score motor run. So, I have shown you this path in one of the above attachments. Please recheck and or, probe by using an Alligator Clip Jumper to bypass each switch in the path. Obviously, to by pass both items in question, you would jumper from Blu-Y at the Ball Trough Relay switch, to Y-O on the Center Target Relay Coil. If it energizes, move the jumper to put only one of the switches in question back into our path. And figure out which switch, or wire run is bad. Tug on the wires as each switch to insure good solder joints. Besides cleaning the points, make sure the points are firmly stamped into the leaf blades. Floating points are sometimes a problem.
