I've got two EM's I picked up (my first of the kind) that were both non-operational - Pit Stop and Blue Chip. The Blue Chip is now working! Going to start tearing it apart for cleaning and restoration tomorrow.

Pit Stop is proving to be a bit more problematic and I'd appreciate any thoughts on the below.

1) There are three coils that are locked on when game is turned on: Lock Relay, Replay Relay, and Coin Relay.
2) G.O Relay, Reset Relay and Score Reset Relay are firing, but not locking on.
3) Reset Relay I believe is a bad coil. Metered below 2 ohms.

I am assuming that #3 is the reason the game will not reset. This seems to make sense based on the Williams start up sequence.

I'm going to order a new coil (duh), but I'm also wondering about the coin door switches.

Schematic shows 5, 10, and 25 cent switches. I only have a mech in the coin door for the 25 cent switch, which had a broken blade which I replaced from what I assume was the 10c switch. There are no mechs for either the 5c or 10c switches. My question is: Do these switches even need to be wired up for the game to reset, or only to accept and register coins/credits? Is there harm in not having any switches wired up in the coin door if I set the game to free play at the credit stepper?
