I have a Darling pinball that I have got partially working. The problem I have with it now is it will not score 100 or 1000 points and the chimes do not sound on any PF hits. The 10 pt PF all work though anything that is suppose to score 100 or 1000 points will not score. The pop bumpers pop down but does not score the 100 or chime. If I score 10 points when it reaches 100 it does not register 100 pt and the chime bell sounds once and the chime coil stays energized. I have gone through all the PF contacts and all appear to be set correctly, have also gone though the score motor contacts and verified all set per the schematic, also looked at solder connections, jones plugs and any unusual. I did notice a strange wire on the lock relay coil contacts (partially melted), verified continuity, not sure if this is an issue. This is a two player machine and both score reels function the same only score 10 pts.
I'm not sure if the lock relay is suppose to stay energized when the game is started but it doe (see picture) and the coil 2nd photo with circle around it stays energized after the 10 points passes 100 (though does not score 100 on either reel)
I have attached the schematic
I just got into the EM's, any help is much appreciated.
