Hello pinsider,

I hope someone can help me figure this out. The topper flashers of my pinbot arent working. Two flashers on the playfield wont work as well. Its the flasher left next to the vizor and the right slingshot flasher. I checked all the relay boards and replaced what needed to be replaced. Checked all transistors on the mpu, no problems. I reflowed all the snubber boards but still no go. Hoping that someone here could point me in the right way.
Thank you for your answers.
Kind regards, kevin.

Thanks for the answeres and sorry for the confusion, what i did so far: checked all resistor boards and replaced what needed to. The a/c relayboards (snubber) where resolderd. Check on all restistor boards and relayboards for lose wires. Replaced all the flashers bulbs with new ones #89 and 4x #1251. Checked all tip transistors on the MPU no problems. Cant find the problem?

8 x 1251?? Yes i have got a voltmeter.

Ill try that and come back on this asap! Thank you.

Fixed the topper lights thx grumpy! Now the only one that needs fixing is the flasher left of the vizor on the playfield. Does someone know the corresponding resistorboard?
Thanks for all the help.
