917-1 extra line continental problems

[sbmania]

I just picked up a 917-1 and am having several problems with it.  No matter how many coins are played, the line unit always steps up to the maximum after the first coin is played.  If I manually reset it, it will immediately step back up to the max.  Is this normal?

Also, it won't pay on any winning combos or on any lines.  If I switch it to credit, it won't step up the counter either.  However, if I manually step up the credit meter, I can use the white button to play the credits.  Anybody with some suggestions?  This is one complicated slot!!

not normal. 


there's a "pay detect trip relay" and a "j.p. detect trip relay".  If either of those is tripped, you'll have your line unit issue. 


looks like both of those are electrically reset, so they will look like a pair of coils at right angled to each other operating a shared switch stack.   From Maurice's 917 pics, they are on the edge of the top insert panel.


take a look and see if one is tripped (usually that means the switch stack is down).  If it is, manually reset it and see if the problem goes away.


the pay detect trip relay resets via the same wire as the line unit, so if the line unit is resetting but the pay detect isn't, it could only be the reset coil itself, the wire, or it's resetting but tripping immediately.   The reset pulse comes from a line unit '0' switch.  The '0' is one of the ones poking out over the white plastic ratchet on the line unit and gets shoved open by the white pin when the unit resets.  You'd want to check the switch with the wire going to the reset coil lug ... schem says it's grey/red and a wire segment goes to the pay detect trip relay reset coil.


fix the line unit issue first and if it's the pay detect trip relay, that may change the payout behavior.  If still not working,  then pick whether you want to debug coin or credit play and we can go from there.  The game has diodes all over the place, so some techniques for payout testing won't work. 


do you have a voltmeter / ohmeter / jumper wire?


I split your post into a new topic so more people are likely to look.

If the line unit is mechanically in nature.
Depress and release the step up plunger, observe what happens.
If the unit advanced completely to the last stop, check for obsessive wear, missing spring(s)
and or bent levers/control arms.

I've got an update!  It looks like the jp detect relay was not resetting and was causing the line unit to step up each time a coin was played.  I manually reset it a few times and then it suddenly started resetting correctly.  Maybe the reset latch mechanism was mechanically binding and working it a few times fixed it?  In any case, the machine now coins and pays out as it should.  I will continue to play it to see if the problem reoccurs.  Thanks for all of the help so far!

The slightest particle or oxidation will disrupt continuity causing a malfunction.
If a latch is involved, it’s possible that it was stuck, but rarely happens as the machine
was designed to operate thousands of times without fault.
Unless it was lubricated with some heavy grease.


Glad to hear it’s running good for now.

This is crazy you have one of these!  Maybe they are more common than I thought.  I have one also and its giving me troubles.  I need a schematic.  Ill start a new thread and explain.

Also one other thing.  I have two of these games and one has brown glass and the other green.  What color is yours?  I don't think either of mine are faded because the fruit symbols are identical.
ThanksE

I actually have two also!  One brown and one green!  My green one is a project for sure and might be missing a few minor parts.  I might sell it as is since I have the other one running.
I found the schematics for mine right here on this website!  I took the file to Staples and had them print it out so I could read it better.  Think it only cost maybe $5 or so for printing!

I'm resurrecting this dead thread!  After years of flawless operation, the Extra Line Continental is once again acting up.  It started by intermittently stepping up one of the steppers several times after I insert the first coin in it.  Sounds just like the stepping noise that is made after normal game play when a winner it made and the game is heard stepping down during payout.  The stepping noise does not continue when coining up coins 2-6.  Only first coin. 
 
Now, the winner paid light is on continuously, the first coin step up noises are still heard, and if I hit a winner, no coins are paid out at all.   I am trying to work my way through the pile of steppers and relays in the game but I'm not seeing the problem so far.  Any suggestions on where to look first and how to proceed?  Thanks!

if the winner paid light is on, then the line unit stepped all the way up.

the line unit should reset on the first coin played, and should only step up if the pay detect trip relay or the J.P. detect trip relay trip.

suggest first step is to reset game and after the line unit steps, look at the pay detect and J.P. detect trip relays and see what they are doing.  Those relays appear to be electrically resettable trip relays, so they are dual coil assemblies - one coil trips, the other latches (resets).

the pay detect relay should reset at the same time as the line unit reset, so the J.P. detect trip relay is more likely to be the problem.  If it's not resetting, check a switch on the reset relay with brown (60-7) and yellow (30) wires.

I don't have pictures of those relays (or a manual), so if you want to send highest possible resolution pictures of them to slotpics@cdyn.com, that'd be great.

Cleaned the points on the odds reset relay (along with several others on that bank for good measure) and the game is now operating correctly again!  Thanks for the help as always!!  This place is the best!

[wolftalk]

great.

I uploaded your relay bank pics to https://bingo.cdyn.com/slots/917-1%20and%20917-2/pics/

as shown in below, you've got some modifications that seem mostly to be in the jackpot lockup stuff and the jackpot meter relay ... neither of which really matter.

if you get a chance to email a pic of the entire front of the machine, that would be great.  The game is one of the most complex EM's that bally made, so lots of stuff going on in there.
