HI all - I hope somebody can help with my issues - new purchase, as a project but this is my 1st Gottlieb.
3 Issues that I think are probably all related:
1. Half of my coils including the left flipper are receiving 12v. the other half 60v?? I have checked the driver board input and all items are receiving 50+ volts. but testing the mosfets with a voltmeter - half only show 12v? any ideas? is this a mosfet issue or something else? please not a new driver board...
2. I can't get into the diagnostic mode - I can play a game no issue but the left flipper is doing nothing in system setup - is this because it does not have enough volts? I reckon probably?
3. I had had to remove a dead coil - could this be the reason for all of the above? some other coils have 50v but are not triggering - is this because the coil is removed? They are not all on the same circuit according to the schematic.
So please if anybody has any experience and can help - greatly appreciated..
