Title says it. Ill turn it off and on and it will blow every once in awhile.Is for Solenoid secondary. Also when I turn the machine on the flippers sometimes flip and stay.

Any ideas?

Nothing?

Together with your other topic (attached below), you might think that something is wrong with the 'blanking'-signal.
Flipper coils and maybe other solenoids getting activated all at the same time.
Try re-seat all ribbon cables

Does reseat mean buy new or redo the connections on the boards? I didn't think one would have anything to do with the other.

arent "staying" flipers related to fused(shorted) transistors?
ps. especialy if fuse is blowing?

Is there a way to test?

Does reseat mean replace or just resolder?

Just pull them and reconnect them firmly into place.

If machine doesn't blow fuses and flippers stay down during startup, it might have worked.
If not, something else causes the fuses to blow.

Switched the cpu power board and opto board with judge dredd. Switched all cable ribbons. Same prob on DM Dredd works fine. Guess the boards are just fine.
