Hi,

I bought the Ultimate MPU and solenoid board for my Globetrotters. It works few games but both left flipper are not working now.
When I do a solenoid test the left flippers are working half the time (I keep the flipper buttons press during the test). They never work in game, when I press the left button in game I can ear a noise but the flipper never move. There is no problem with the right flipper or other solenoid.

I check the soldering, the continuities, I changed J1 and J2 connectors, I have a new rectifier board with new connector. Nothing is blinking except the cyclone turning. 43v 12v and 5v LED stay on. Q15 LED stays on too when I start a game. The MPU seems to have no problem.

The fact that the solenoid flipper test is working half the time make me think that the solenoid board have something wrong. If I let the solenoid test running the left flippers really work 50% of the time, it seems completely random. When they work they are fast and strong and when they don’t they are not moving at all.

Could someone please help me ? I have tried my best, I don’t know what do next.

Sincerely,

Thank you for your quick reply. Both left flipper assemblies are completely new except for the double switch that was not in stock. I adjusted both switches correctly, I double checked, I can see the leafs moving when manipulating the flippers, the contacts are clearly solid. The double switch is a bit corroded but was working before.

Thank you so much, you are an expert. To be really sure I used sand paper on the double switch contacts and it worked. I really need to change this double switch.

Do you think I can arrange 2 of them to make the one I need ? It seems that I can’t. Here is a picture of the double switch I have.
