Working on a friends STTNG and after rebuilding the high voltage section of the DMD board and a few other things, I'm now tackling two seemingly related issues - a reset issue when hitting 2 flippers and the flippers are very weak. I have been working through Clay's guide and the PinWiki, but thought I'd check if anyone had come across this issue which might help pinpoint which tests and replacements to focus on.

Main symptoms:
- Hitting 2 flippers resets the machine, flippers are weak otherwise (I have disconnected the upper right flipper to test just the two lower flippers).

- Using another driver board fixes both of the problems (resets go, and flippers are strong again)

Voltages appear to be ok on both the driver board and the CPU board:
TP1 (12VDC unreg) = 13.5V
TP2 (5VDC) = 4.98V
TP6 (50VDC) = 74V
TP7 (20VDC) = 22V
TP8 (18VDC) = 16.2 (maybe low?)

Power at CPU board was 4.96V I believe

Just as a follow up, I replaced connector and header pins J101 and J114, while I was there I replaced C4 and C5, and now it's working all good

Not 100% sure, but from what I've read it was most likely the headers not the capacitors.
