Ok, pictures and video included. Explaining this is going to be a bitch, but I'll try anyway.

It doesn't look like the swing arm is making any contact with the switches in either activated or unactivated position. I can't figure out how to adjust it so the roll bar is putting pressure on the switches to begin with. Arm seems to work, solenoid activates, but it doesn't help if there's no contact. All of the switches look to be straight and uniform.

With the reset bank not working it means the game never kicks out the starting pinball or finishes start sequence. The other relays on the bank are the game over, second player, last ball and reset control. Below is a picture of the bank flipped up. You can see the switches just sit between the roll bars.

Larger picture can be found here.

Finally, here's a video demonstration of the problem. Hopefully it will explain things better than I ever could.

Any help?

The relay bank is in the reset position in the picture and video there is no adjustment needed there. What happens is each individual relay kicks out and drops down and rests on the reset arm and then those white plastic rollers engage the switches. Then when you start a new game the reset arm kicks them back into the position they are in in the picture/video. Notice how the switches have clean spots on them where the plastic rollers have been in contact. Your problem with starting a game is somewhere else. Maybe the start relay or could be you have no credits to start a game.

Thanks Glennon. This is my first project piece (and EM experience) so after I saw it didn't appear to make any contact when moved I jumped to the conclusion that it was what was causing the ball not coming into play. Thanks again for putting my mind on ease. And the hunt continues...

Here is the start up sequence for your game. Go through and check these in order.

1960s & 1970s Gottlieb Start-Up Sequence.
Games with score reels.
Inserting a coin or pressing the coin door start button (Gottlieb calls this the "replay" button) activates the "S" (start) relay. The start relay will lock on from its own switch and a score motor switch.
The "S" relay will energize the main hold relay to illuminate the game (if this is the first game after power-on).
The "S" relay will start the score motor running.
The "S" relay and the score motor increment the total play meter.
The "SB" relay (the secondary start relay) is activated through the score motor. The "SB" relay energizes the reset relays ("Z1" and "Z2"). If a single or two player game, there may be only a "Z" relay.
The "Z2" relay will reset the player 3 and 4 score reels to zero through the score relays (4 player games only). The "Z1" or "Z" relay will reset the player 1 (and player 2 if present) score reels to zero through the score relays.
The "SB" relay resets the player unit through the score motor.
The "U" relay resets the reset bank (or Ax, Bx, relays on 1975 and later multi-player games and Ax on single players) through the score motor. It also resets the bonus unit or drop target banks (if the game has these).
On multi-player games, inserting more coins or pressing the coin door start button activates the "PBx" relay, through the score motor. The "x" represents the player number (from two to four).
If the ball is in the outhole, the "O" relay activates. The "O" relay, through the score motor and a switch on relay "XB", will kick the ball to the shooter lane. Note: the "O" relay will not activate unless the bonus unit (if the game has one) is reset to zero (there is a bonus unit zero position switch).
When the ball re-enters the outhole after game play, the "P" relay kicks the ball back to the shooter lane. Switches on the "XB", "ZB", "P" relays and some score motor switches advances the player unit (if present) and player relays ("PBx").

Hope this helps,
Glennon
