4 Problems and Solutions
4.1 Power Problems
4.2 Solenoid Problems
4.3 Lamp Problems
General Illumination circuit for the backbox are through connector C9 on the black and yellow wires. General Illumination for the playfield circuit is through connector C9 on the red and brown wires.
Switched illumination is through connectors C3 and C5.
4.4 Switch Problems
The original "ball and chain" tilt assembly is very flimsy and not very good. It is suggested to replace it with a Williams # A-15361 Tilt Assembly for much better operation since it uses standardized parts.
You can also use these Marco Specialties parts along with two 6-32 wing nuts to make a complete tilt assembly:
(1) # 04-10346 and (1) # 20-6502-A
The standup switches look like bent up paper clips just like the switches on Sentinel/Wonder Wizard home pinball machines. These switches must be kept clean and shiny to work properly. The circled area is the switch. The playfield switch circuits go through connectors C1 and C4.
