I posted this over in the EBD club but haven't got any feedback yet. Maybe someone here can help me out.

I'm wrapping up my EBD restore. And the game is now playing. The issue I need help with is the 7 bank reset.
What is happening is I cannot get the full bank of drops to reset. The two big coils fire but they aren't powerful enough to lock the targets up.
Although when I unhook the individual target drop coils on the bank. I do have the power to reset the full bank. Has anyone else had this issue of not enough uummff? To reset the targets?

It has a new nvram mpu and a new rotten Dogg solenoid driver board.

All the connectors have been rebuilt minus the sound board and lamp driver boards.

The coils are the correct ones. The diodes are facing the right way.

Thanks guys I will look over these things and report back.

Ok problem solved. After isolating individual coils on the 7 drop bank, it turned up no results. I moved down the return line and ended up disconnecting the trough coil. The 7 bank reset, no problem. Tested the coil on the bench and BAM bad diode. Apparently the game didn't care because it was putting a ball into the shooter lane no problem. So the diode was just weak enough to allow that coil to work but pull power off of the bank reset. By way of the 1,9 drop target coil. What a chase.
