This may be two issues, Solar City is only awarding credits on second player and when credits are awarded only the knocker is activated no credits on the credit unit.
Thanks,

Took out the credit unit cleaned adjusted and lubricated the credits are now registering or player two only. Thank you Vec-tor. Cycle the drum units?? Do you mean the score reels, what exactly are the drum units?

Howard 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,
Bert

Vec tor,
Found a make break switch on the player unit second set first switch needed adjustment. Player 1 now awards credit correctly. Thank you everyone for your input.
