Quoted from Chosen_S:
I’m still having issues with my trolls, I need to figure out which capacitors are in their power circuit. Would anyone happen to know?
The trolls won’t work until I go in to test mode and let them pulse for about 20-30 seconds each. I have to do this every time I turn on my mm.
Because the trolls have power and hold circuits they are handled by flipper circuits. Q84 and Q81 are the power (raise) drivers and Q83 and Q86 are the hold drivers. There are no capacitors in these circuits so something else is causing this. I've never seen this before, did both Trolls start having the problem at the same time? Are the flippers strong and working properly when the trolls won't pop up? Check the connectors at J119 and J120, make sure they are not burnt and that they are tight. I would then measure voltage at the tab of Q84 and Q81 (in Solenoid test mode with the interlock switch pulled out, hopefully I don't have to tell you to be careful while doing this as high voltage is present).
