I am working on a Gladiator. The ball trough coil energizes in the start up sequence but stays energized until you reach the last ball. We finally obtained a schematic and it appears this coil is called the Ball Release coil. It is energized thru NO motor 1D switch via Add units relay N NO switch, or thru the last ball relay XB NC switch. Can anyone provide the start up sequence, specifically what causes the ball trough coil to de-energize after the balls have dropped into the trough. I am missing something here. None of the start up sequences described on line seem to fit this machine. It is a 2 player with score reels & a game over relay.

Being a multiplayer game, it probably only has one ball so the ball release coil should stay energized until the game is over. There is probably a switch in the ball trough that closes along with a switch on the ball count unit that together indicates all balls have been played and then releases that solenoid thru a relay when the game is over.

According to the schematic I have for Whirl-Wind (which is only slightly newer), the ball release coil stays energized from startup thru a switch on the last ball relay that is normally closed until the last ball relay is energized thru the balls played unit once you get to the last ball.

You say yours does not show it switches thru the last ball relay so maybe the circuits are slightly different, but operation should be close to the same.

Either way, that ball release coil should stay energized until the last ball or end of game.

Thanks. Turns out to be a problem with a replacement plunger on the coil that must be a little shorter than the original. Coil stop looks good. Put in a different stop that was longer but it is too long & the trough door doesn't open far enough. I'll make a spacer to solve that.
