well, im stumped here...
checked,cleaned,repaired contacts,and steppers,
fitted new credit unit,
turn her on.
back glass lights up,tilt is showing....
no lights on PF....no motor...if i push in and hold the tlit hold relay the PF lights up.
but nothing else happens
any ideas #$# #$#
-
got a schematic ?
Gottlieb's have a "defeat" switch - looks lie a tilt on the bottom board... Feeds power from the transformer. If this is not closed, nothing happens.
Check Fuses
Check "hold Relay" is on...
Double check with the schematics !

something really f**king simple...somewhere!!!! <.>
id check tilt and im assuming no reset cycle? check score motor basic system so to speak so reset cycle can commence
btw i love this EM...that spinner and later bonus is the bomb ! :D
-
no schematic yet *.*...
hold relay dosent pull in,but coil checks ok..
will be somthing simple i know..been through and cleaned everything,twice
switch your talking bout nino,is all good
cant wait to hear her reset *%* *%*
-
I know this sounds stupid,
but turn game on - open door and manually close switch to give credits, then press game start switch.
.... Let us know what happens
-
surely not !!! i had assumed, but then you know what they say about assume !

nah ...nothing.... *.* ...been at her all day,
no life except when i hold in the tilt hold relay,then pf lights up
witch is a good sign i think *%*
nah still nothing....bee

its a really fundamental problem so to speak, to not initiate reset cycle when depowered, is odd... for curiousity advance a couple of things out of whack and repower, maybe a clue here or there ?
-
Ok.
I dont know the game, but it is a GTB from 75 or 76.
Reason i asked you nto do what i did before is that some of these old EM's have no attraction mode. You can turn game on and its completely dark - nothing. Game only lights up when a coin is deposited.
Ok, but now weve got that out of the way....
Inside your machine is a relay that will feed the power to the PF etc - this is out. if it were a Wms i could point you to it straight away.
But try this - open up the PF with the game on. Now be REALLY BLOODY CAREFUL and manually hold in the 115v relay - use the white leaf spacer to do this - do all the lights come on? With this manually held in - you may even be able to get into reset mode.
If this works then look at the "S" relay - one or more of the leafs is out.
Get back to us again when youve done this - if you dont get back ill assume youve electrocuted yourself and call the ambulance

nah, the only switch to light the PF is the tilt hold relay..still cant get it to stay on though.. #$#
still alive but %.% %.%
great new,just gave the fuses a wriggle and she burst into life....f--kn beauty,motor keeps running but
keep you's posted....yessssss () () ()
-
115V doesnt work?? But TILT does??
Check ALL tilt switches inc door slam, plumb bob, cabinet tilt and the override switch in bottom of cabinet ( the one NIno told you to look at).
sounds like one of these is wrong - TILT is enabled
-
ok,......as i dont have a schematic.....[if anyone reads this and has one or can do a copy]
she's goin,,,,but the b relay is pulled on.[anyone know what this is]to the extent she starts smokin..
no doubt there'll be other issues,...getting there but #*# #*#

The "B" relay on my pioneer (around the same vintage) is one of the pop bumper relays. Maybe a stuck switch is causing it to lock on & smoke.
-
STOP !
Smoking in an EM is a Serious matter that needs to be dealt with properly. It will be a "locked on" coil - either a bumper or a relay. You need to locate the cause of the issue. As mentioned, if it is the bumper, check the switch. The chime and 10 or 100 pt relay may or may not go off, as it is common for the second set of switches on the bumper switch stack to be broken ...
Please locate the smoking coil.
It could even be the second switch stack is open - causing the "B" relay to stay "on" - But this will cause the chime coil and scoring coil to stay on.. this is switch issue and it needs to be fixed...
First check - compare the switch stack in each bumper.
-
^^^,yeah its all good,was pop bumper stuck...
can play a game on her now..but...still a few issues.
on start up,the motor keeps running till i dis-engage the ax relay..but wait theres more #$#
then motor stops..then i have to advance stepper in back box 9 steps till it shows 1st ball....
then you can play a game normaly.....
cant be much,just knowing where to look..
jeezz,the bonus countdown on this old girl is quick %.% %.%
-
OK - is looking good.
Download the GTB 70's start up sequence from Marvins guide in the 30's - 70's EM guide, this will give you a heads up on what triggers the AX relay etc
-
This is where you really need the schematics to see the relationship between the AX and Score motor. Yes - it will be a simple fix, but only with a schematic..
From memory AX is in the head.. Lets try something easy.. Unplug the game, disconnect the mains.. Disconnect the plugs from the head and clean them with a wire brush - just the "males" ends. Look for loose wires. Reconnect..

"Stepper in Back Box"...
Which Stepper ? The "Player unit" ?

"Stepper in Back Box"...
Which Stepper ? The "Player unit" ?
hey nino,yeah i think its the player unit...although theres a stepper in the front of the cab,witch selects players 1-4... #$#.

The player unit is the unit you are advancing manually ? I think the player unit is not being told to return to "home";
Here is the section in Clay's guide - point 7;
"On a 4-player game, the Player Unit in the backbox increments until it reaches the Z1 position. The Player Unit stops and the Z1 relay in the backbox energizes."
Did you clean the connectors ?
-
yeah connectors cleaned...checked p5a and p5b as per clays guide.
now when i start her..ax relay still stays on,and motor keeps running..but
she's at 1st ball,i dont have to advance player unit
tiny bit closer %.%,plays right through when i stop the ax relay,1-4plys, all good
tempted to take PF off again and go through main switch bank again #$#

OK - So you DID have a connector problem ?
Sounds like the game sat idle for 20 years, and by simply playing 20 games - it might come good..
See how you go after a few games..

yeh played a heap of games,still have to dis-engage the ax relay,to start
oh to have a schematic now %.% %.%..
-
need the schematic about now...
AX is held on by a combination of BX, ball return, 1st ball relay, and replay unit (score motor) - This is from my Pioneer manual.
Check the "ball return" switch - is it constantly closed ?
There could be a misadjusted contact on the BX or replay unit... But I can't tell you what contacts are related on the replay unit..
Something is holding the AX ON...

ball return switch is open????is this right???? #$#
-
Yep - When it closes, the AX switches on..
There's a switch on the BX that also keeps AX on - I can't tell without a schematic.
