Mata Hari
I'm new to working on pinball machines,with that said I have MATA HARI 1978
machine when I turn it on the MPU flashes 7 times,after it goes out, the power-up tune does not play. When I press the self-test button and get to the solenoid test,the #'s 3-4-5 which should be the chime solenoids don't work,instead the thumper bumpers work,and they also work when they are tested as the bumper #'s. Any thoughts???
I also changed the lamps from #44's to #47, the new ones seem to dull.The game doesn't get played that much anyone think there will be a problem going back to the 44's even though they draw more power and run hotter?

was my info helpfull on repairing the solenoid problem? i think to many 44's leads to redtifier board connector burn. who's to say how long a machine can be on without heating up playfield plastics and connectors
