Ok. I have an issue that is really upsetting me.
Bally Embryon.
All-tek driver board.
New power supply board.
Everything was working great.
Then the left flipper starting sticking.
Now the flippers work but no: sling shots, ball launch, or the saucer kick out.
The bumpers work. All fuses are good.
No obvious broken wires.

What am I missing? vid1900?

Thanks,

Milton

dothedoo: No.
And no obvious wire breaks.

Milton

vid1900: I will check tomorrow. The rectifier board works in another machine.

dothedoo: It should be obvious. I can't find the damn thing. After lunch I will post the voltages and dig up a schematic. You would think it would be the saucer because it's near the bottom and would be
easy to break. I have the knocker, all thumper bumpers and flippers. Missing the ball launch (another easy place for a wire to break) the slingshots and the saucer.

Should not be that difficult!

Well folks, it was obvious. Just no to me. A friend was over while I was working on
the machine and started wiggling wires on the coils and one broke off. I re-soldered it.
It WAS the offending wire!

I don't think I would have found it. I was just about to reflow some other connections on another
coil!

Problem solved! Grrrrrrreat.

JKnPA, absolutely!
