DC, I don't have schematics for JP, however going off other EM machines, power needs to go to all units you mention thru contacts on the 'AX' (Reset control relay) and the 'Q' (Game over relay) give these a check. The main wire colour which feeds power to all these units will possibly be 'Red with a white tracer' which comes off the '10 amp playfield' fuse, thru the 'bounce switch' on the base board . See how you go!
