pop bumper stays activated

<< < (2/2)

shardian:
Been a while since I read the DE manual, but I thought the rev. 3 board had extra hardware on the board to stop pop bumper coils from locking up?

Anyways, crack out your DMM and ohm the coil. Then look at the driver transistor on the board. Even if it wasn't bad before, it's probably fried now.

pinballwizard79:
where is this pop bumper board?

Q*Bert_OP:
It's one of the driver transistors on your MPU board. DE & WMS Sys 11 combine the MPU and driver board circuits onto one board.
