when you say you put jumpers on switches, I don't know which side of the switch. Ya gotta say the colors of the wires you put the jumpers on (use the wire color abbreviations on the schem).
I'm also not sure what the problem is. Is it:
A] the ball is sitting in the outhole, but the outhole relay doesn't power after the bonus counts down
B] the outhole relay powers, but the ball doesn't kick over to the shooter
if the problem is [A], I'd do this:
1] play until the problem happens
2] remove ball from outhole
3] tip up the playfield and attach one end of a jumper wire to point [A] (green line in schem below)
4] touch other end of jumper to points marked in X from left to right until the outhole relay powers.
that'll tell you which switch / wiper isn't working.
if you wanted to use a meter instead, jumper the outhole switch closed (A to leftmost X), then put one meter probe on the power line (yellow dot) and other probe on all the X's from left to right. When you get something a lot lower than your transformer voltage, the problem is the device to the left of the X you are on.
for all the above, the assumption is the E-1 switch is working. If credits decrement reliably when resetting the game, it should be ok, but you can verify with the outhole switch jumpered closed. Put one meter probe on A, the other on the B-O wire on the outhole relay coil to verify you have transformer voltage (30V?).
I've been using A because not enough of the schem is in the pic to see what the wire color is ... (nag nag )
