picked up a High Speed about a month ago that was literally about to go in a dumpster. So $800 in parts later I have a 99% functioning game that surprisingly looks pretty good and plays great. The ONLY issue is the upper flipper does not work.

New flipper board, new flipper assembly, coil is getting power, coil fires when shorted, tested continuity to the cabinet flipper switch and test good, cleaned cabinet switches, etc....

Kind of out of ideas at this point.

Does the power daisy chain off the bottom flipper?

Maybe check that out ...

Try jumpering the EOS switch too ... to rule that out.

Quoted from woody76:

it does, checked all that.

Jumpered the flipper switch?

Coil and EOS wired correctly?

All simple stuff ... but worth double checking.

Here’s my upper flipper wiring.

Your new coil has 1x diode like this one?

so its getting power, you've confirmed that, functions when you ground it out...have you checked the continuity of the ground return to the J19 pins on the CPU Board from the flipper coil ground?

Have not, will do asap

I would put one end of my DMM on J19- pin 1 the other to the blk/yw wire on the coil and press the right side switch...should have continuity...as should the lower flipper wire blu/violet. If no continuity work your way back. I had thought the grounds connected to each other, but I believe I was thinking of the power wires for the Right flipper.

done this morning and tested good. I also grounded the black/yellow wire at the cabinet switch and coil fired.

It will just not work during game

Hmm Its possible that the lower flipper switch is making the ground connection as that is working properly thus giving a good continuity reading . Some how that coil ground is not getting to ground...follow that wire back and in the mean time I'll take a look at my machine tomorrow morning and see where it goes.

Both Right flippers use the same ground lead ORG/VIO back to the MPU 1J19 pin 1. Since the right Lower flipper is operating that eliminates the ground wire as the fault.

it eliminates the portion from the flipper switch to the MPU, but I'm guessing there is an issue at the switch

Yea, that is my thought as well. It is the only remaining part that is in the circuit that remains.

The flipper button has two sets of contacts...most likely the plunger in the second set of contacts is broken for the upper flipper. To confirm, swap the wires on the flipper button and see if the upper flipper starts to work.

jumpered the cabinet switch lugs and started game and upper flipper fired and held. Ordered a new switch.

Thanks everyone!!

It’s usually something simple.

always, I should have known. The thing was a train wreck when I got it and had some pretty serious issues. I fix them all and let a $5 switch kick me in the balls.
