hi,after some help,just purchased a gottlieb super spin.
powers up,push credit button,resets,ball comes out...
but flippers bumpers,score dont work??
any ideas. ^&^
thanks dave

Check that the "player 1" light is on and the lights above "player 1" scorereels are lit. The "ball 1" light should also be on. These games have a "player unit" in the backbox which are temperamental. If the correct lights are on, then we can rule that out.
From memory, there is a switch near the ball shooter. Check that the contact close when a ball is sitting in the shooter lane.
-
Yes... good call Nino.. ball needs to go over a rollover switch to activate the flippers and bumpers.. its done on the way to the plunger tip
-
hi again checked that just then..
still no go.
it is just the bumpers & flippers dont work.
whats next....
thanks
-
Ok... some basic stuff is needed before it gets a bit complicated... lift up the playfield and make sure that when you push the bumper ring down, the leaf switch underneath makes contact... the base of the ring sits inside a spoon.. this then presses down on the contacts.
Same with the flippers.. look at the contacts on the flipper buttons and make sure you have contact when flipper is pressed.
ALL coils on an em work on the same voltage circuit.. so if slings work, so should everything else. Check to see if you have voltage with a DMM
If all this is OK, then we need to probably look at some relays
-
will check...
back soon
thanks... !@#
-
check,all that part seems ok...
^&^
next....
-
Whats the voltage at the non working coils?
-
Are the sling shots plus other not working as well ? If not I would be checking the 'Game Over' relay. From other machine schematics (1975 & 1976) there will possibly be a set of (NC) contacts housing a RED w/ WHITE tracer. Ensure that they are clean and making connection.
-
will have to borrow a multlmeter.
to check voltages.
will also check the game over relay...
thanks
-
its all got in the to hard basket..
think l sell the machine... ^&^
-
Mate ... don't give up ! Half the fun is tracking down the fault .
Have you checked the
"'Game Over' relay. .. set of normally closed contacts housing a RED w/ WHITE tracer. Ensure that they are clean and making connection."
Where are you located ? Maybe another member would be kind enough to drop by and give you a hand ?
EM's are a lot easier to fix than electronic pins I reckon .
The whole principle revolves around switching an earth to complete a circuit to a coil .
Most likely all that is wrong with your game is an earth is not getting switched through properly .
Either that or there is a break somewhere on the power side to the coil/s.
-
If the slings are working but flippers and bumpers not.. then it strongly suggests a broken wire on the power line... would be easy to find... go to slings and follow from there.
This is the original reason why i asked you to check the voltage at the non working coils
-
no the slings are not working.
will look a bit further
^&^
-
Ok... but the game spits the ball out to the plunger right?
We need to know exactly what is working and what isnt.. then we can help you
-
game turns on ok.
ball comes out,no flippers,slingshots,bumpers,scoring.
when comes out for second ball,stays on first ball on backglass.
does come up for second player.
push tilt works.hit the roto spin,makes the noise but thats it. *!@
thanks you for this people..
-
OK.. couple of faults... the ball count unit isnt advancing for one.
Do the score reels reset at start up?
-
the scores are on 00000
if you move them manually,they reset.
-
Score reels resetting to 0 is a major plus .
So.. you have 2 problems
1) no playfield coils getting energised .. Have you checked the "'Game Over' relay. .. set of normally closed contacts housing a RED w/ WHITE tracer. Ensure that they are clean and making connection."
2) Ball count unit .. can you manually operate the plungers on this to see if the unit moves freely or does it seem gummed up . ? Also, are the power and earth wires firmly attched to the coil lugs on this unit .. give them a bit of a tug to be sure

+1
Check or replace the backglass "tilt" and "game over" globes. Sounds to me that the game is not properly resetting.
If you "lose the ball", does the "ball in play" advance to "Ball 2" ?
-
no stays on ball one,does not advance...
-
I think you should concentrate on the ball count unit .
Specifically , look for zero position switch (red/white wire on each side ?) , this switch should be normally closed .. if that switch is open it will cause the problem you have (no playfield coils working) .. I am going from a schematic for a '73 gottlieb but I expect your game will be the same

going to check out saturday...
will update...
-
pushed rest relay,stopped machine from winding over.
checked relay on the backbox.
moved manually the plastic cams,and checked contacts.ok
now machine lights up,thats it,does not kick the ball out.
show game over or tilt.
next test...?

Mate .. it is really hard to help via an online forum if you
a) aren't doing what we rexommend and
b) aren't clearly communicating the result of doing what we suggest
Your last reply mentions nothing about the zero position switch on the ball count unit and also now you state 'stopped machine from winidng over" which implies the game is not completing reset cycle when you start a game but before you indicated it did ^&^

Yeh.. i kinda gave up

!@# !!!
is there anyone close to come and have a look,,,,,,,,
-
Where are you?

at warragul victoria,
is anyone want to have a look at fixing the machine....
