Quoted from V_piscopo:

Just joined the club. Having an issue with my upper kick out hole. Switch registers in test mode and game play yet coil won't fire. Coil does not fire in test mode or game play. when coil is grounded it fires, when transistor is grounded coil fires. Coil tests good. I do not have a manuel, wondering what connector controls this coil? All other coils seem to work in game and test mode. Thanks.

Quoted from dendoc:

Time warp tech issue - appreciate any help.
Been playing perfectly, turned it on and all boots well but when I press start, ball doesn’t kick out and background sound stops. If I kick the ball out manually all plays well.
In test mode, coil 1 doesn’t fire. Wires look fine, continuity to connector fine.
Any ideas? Thanks

Quoted from WhiskeyPinball:

So I was looking at the MPU more closely to see the 5101 Chip. Prior owner must have installed a new chip (per photo). Could this chip be the cause or is it comparable to a 5101?

That chip is in a dip socket though
