I'm restoring a Bad Girls and have installed a new power supply (gulfpinball) and a new cpu-board (mypinballs.co.uk) and installed some new connectors since the old one had been damaged from battery leakage on the old board.
Now - the game boots up as it should. Pop bumpers, slingshots, droptargets, switches, lights, sound, displays etc works fine in game play - but none of the three flippers work. Checked all fuses - they all work.
So where do I start looking on this one?
Is it on the driver board - and does anyone know what transistor/resistor that needs to be checked?
Or could the problem be anywhere else?
Could this have anything to do with ground mods? None of those have been done to this game - but I read here somewhere here that it's not necessary on these late system 80b-games.
Any help on this would be great!
