Now manually activate the start relay (I use a stick -50volts ouch) On my Bally it is 5th relay from front on right bank of relays. Does anything happen.
By the way are any of these relays activating (on hold) when powered up ?
Make sure all bounce switches are closed and clean (clamp a alligator clip on them)
Tilt roll switch is not contacting housing (Thats that thing above the tilt bob) it usually has a ball that rolls along it.
Finally make sure the start button contacts are making good contact.
Also make sure there is a ball in the return or close the switch
This is the start up sequence :
Bally Start-Up Sequence.
1.Coin is inserted into the game. The coin relay will energize. It will stay energized through its own hold-in switch and a score motor switch. If the credit button is pressed (instead of a coin being inserted) and there are credits, the credit relay will be energized which energizes the coin relay.
2.The coin relay will energize the lock relay (this turns the general illumination on). The lock relay will stay energized through its own hold-in switch and a delay relay switch.
3.The coin relay will energize the reset relay, through a game over relay switch (if your game won't start, try cleaning the contacts on the game over relay; a very common Bally problem).
4.The score motor will operate. This will energize the score reset relay(s). The score reset relay(s) will attempt to clear the score reels to zero. This is done by operating the score motor. 5.Each turn of the score motor will operate the reset relay once, which in turns moves a score reel one position, until the score reel(s) are at zero. If the score motor continues to run when a game is started, there's a good chance the zero position switch on the score reel(s) is dirty or mis-adjusted.
6.The coin relay, through the score motor, will advance the total play meter.
7.The reset relay, through the score motor, will reset the stepper units (zero the ball count and player units).
8.The coin relay, through the score motor, will decrement the credit unit.
9.The coin relay, through the score motor, will energize the game over latch relay coil.
10.The coin relay, through the score motor, will energize the 100,000 relay latch coil(s) (if the game supports scores greater than 99,999).
11.If the outhole switch is closed (single ball games) or the ball trough switches are closed (multi-ball games), a ball is released to the shooter lane through the outhole relay (single ball game) or ball release relay (multi-ball game) and the score motor.
12.On multi-player games, the credit button may be pushed again to add a player. This time the coin relay will not energize the reset relay. Instead it will (through the score motor) advance the total play meter, decrement the credit unit, and advance the coin unit.
