I would lubricate all moving parts...
Plyr 1: check for broken wires and lubricate pcb.
a) cycle the drum units.
Starting with the limit switch on the replay unit only because it's the easiest switch to find,
Inspect and diagnose this circuit with Alligator clip jumper wires.
Note that this is the circuit for awarding a credit at 23,000

pasted_image (resized).pngHoward after some more work/exploring on the machine, the credit unit gets credits on high score for the second player only. On special both 1st and second players are awarded credits. So what is missing in this issue is number one player getting awards for high score on the credit unit. Should I go through this testing I will need to go and pick up some alligator clips that I am sure I’ll need in the future.
Thanks,

You have the make/break on the player unit that could cause problems...
Quoted from Judoratt:Cycle the drum units?? Do you mean the score reels, what exactly are the drum units?
The score reels are the drum units...
If you have the score reels E.O.S. switches intact then you can cycle the units.
By carefully activating the lockin switches to the score points relays...
10 point relay,
100 point relay....
Then you can set all the score reels to 1,1,1,1,0 and activate the reset.
Usually, you can catch a drum score reel hang on a number and not fully reset.
