Checklist before first power-up of an EM
Steps
- Fuses and holders checked; connectors cleaned and fully seated.
- Coin switches undisturbed and game set to free play.
- Every stepper cleaned and worked by hand; every score reel checked.
- Every relay switch inspected for wipe, broken blades, missing contacts and broken wires.
- Tilt plumb bob and ball-roll tilt not jammed closed (common after a move).
- Power cord inspected or replaced.
An old power cord's rubber can crack with age and become a shock hazard; replace it. A cheap extension cord with the socket end cut off makes a replacement line cord (page 8).
