Gottlieb System 1 Drop Targets Issue

I have a Gottlieb Pinball Pool. The two banks of drop targets won't reset on start-up. I replaced the Driver Board and the cable that links the MPU to the Driver Board (A1-J5 to A3-J1). I know that all 4 coils that lift the drop targets are working because I ran a jumper from the flipper coil to each of the coils and I can get them to fire when I press the flipper button.

Any ideas on what's going on? Also, the coil fails during the self test.

Any help from the forum is GREATLY appreciated.

Thanks,
Jim

did you check if there is any fuses mounted prob on playfield for the bank resets. these are usually 1 or 2 amp slo-blo . or there might be aux. driver transistors on playfield for these coils also.

YOU NAILED IT!! I didn't even know that there WAS a fuse mounted on the playfield for the bank resets (I'm a newbie). Replaced it and the drop targets are working again.

Thank you so much for your help!!!
