1973 Gottlieb's "High Hand". Not working

[Randy0777]

Well,it finally quit working  . I had this game for about 15yrs and the only thing as far as repairs was a contact sticking or burnt bulb ,so guess I'm lucky. As of now,the only thing that powers up is the backboard lights  . So reading Clay's write up on the repair guide  ...half of the words I dont even know  .

So,as soon as I grab my volt meter and get some readings I think I'm gonna need some help.

Check the fuse and holder for the 25 or 50 volts used for the relays and scoring motor......

check slam tilt on front door  theres nothing you can,t fix on em pin,s or slot,s

[stayouttadabunker]

Betcha the power supply pin molexes are shot...
Maybe it's time for new receptor pins?
Jiggle the molexes around a bit and see if your game boots up?

[slotsteve]

Theres  no power supply  back   then transformer only

[stayouttadabunker]

oh okay...thanks for pointing that out steve...
mine's too modern perhaps...   LOL
I have a 1979 Stern Stars.

Anyways, with randy's machine -
I'm suspecting some type of dirty wire contacts somewhere in there...
perhaps a blown capacitor?

[Randy0777]

Thanks for the help guys. Just found my meter  (only have 4!!!) Be back soon...

[KirkLasVegas]

Blown capacitor? These old EM machines are AC relays.there is no power supply

[mkd3b]

Check the contacts fot the start sequence relay all the tilt relays and even the contacts for the start button and also where the pinball drops in the bottom up to the plunger.  Also woulndnt hurt to manipulate all the contacts on thwe relay banks.  After of course all fuses have been checked.    Good luck  Oh dont ya luv it when they just stop working for no reason at all.  Gives ya something to do.  Long live the EMs  Gotta love em 

[KirkLasVegas]

If he has no relays or solonoid action its the 24 or 50 volts from the transformer.They are known for bad fuseholders.the pwr transformer has only 2 windings,lighting (6 volt) and 24 or 50 for the rest of ityou can advance the score motor by hand and see if it starts for one cycle.I used to work on EM pins WAY back when...

[Randy0777]

Ok,a few questions....On the transformer I have the 110 at the bottom,but nothing at the top. In the second piicture you can see the relay/switch that has "reset" wrote on the board. If I press that the lights on the playfield come on. It has a slow blo fuse in the back which shows 110 but the three fuses in the front are getting nothing

[Randy0777]

I really dont see how I can advance the score

Is this what your talking about? Back right

[slotsteve]

The relays under the reels do the score but if your not in game mode they may not work

[Randy0777]

I did try moving them,nothing

[slotsteve]

try  turning the score motor under playfd it should run when you turn it by hand

[Randy0777]

Thanks for the replies Steve. Are you talking about the wheel above in the pictures or the other wheel ? The one above I can not move ,the other one  I can spin(the one with all the cvontacts),but nothing happens

[Randy0777]

Oh,one other thing. The Tilt is lit up and I know before when it would tilt out the playfield would also go out until you played a credit

Okay, I'm not pinball guy and don't know anything about this game, but if the playfield normally goes out when the machine is in tilt mode and the tilt light is lit, and the playfield lights up when you press the reset (and presumably goes out when you let go), then it sounds to me like you have a short in your tilt circuit. Something is keeping the game in a tilt condition at all times.

Just an observation from reading the thread.

[KirkLasVegas]

Lets try this again, typed up a in detail directive..and the system lost it....

I used to work on Gottlieb Wedgeheads, 2 and 4 player EM's as well as their electronic machines (Electronic horriblious)
OK....First off you MUST have the 50 volts AC for the relays. I HIGHLY suspect those fuses and holders! TRUST NOTHING! check the fuses and holders with a Ohm meter. Check the transformer output winding with the Ohm meter, then measure it on * AC * with power on the transformer.
You KNOW the primary is working as you have 6 volts AC for the general illumination! comes from the same transformer!
I have NEVER seen the 50 volt transformer fail...EVER! they are bulletproof.When you can measure 50 volts between the common on the transformer and the 50 volt fuseholders then the machine will run or you can troubleshoot it.
Place my bet on the fuseholders/fuses....

Wrong...absolutely wrong. The "tilt" is lit due to the Tilt relay relaxed. The "Tilt" light stays on until this relay pulls in..and it cant without the 50 volts...
That circuit is doing what its supposed to do....

I try to be wrong at least once a day; I have never failed yet.

I agree with Kirk, no sense moving forward until you know if you have the correct voltages. According to your picture the 115vac comes into the bottom of the transformer, the two voltages come off the top. if the solid black wires in the middle are the center tap, then you should be able to measure the 6vac general illumination from the solid black and the black with white tracer. If that voltage is ok then measure from the solid black to the red wire and you should read 50vac. If you have the voltage there then just physically trace the red wire to its fuse block or distribution point. keep your meterlead on the center tap and follow the 50vac until you lose it and then see why it went away.

Thanks for the help Kirk, In the picture of the transformer I have two connections at the bottom(which were the 110V) and three at the top and two whites on the backside...which ones should have the 50V? And when you say ohm out the fuses,I assume you mean the three in the front,right? Only other fuse I see is one near the transformer.

[Randy0777]

Ok,ignore the above  . Thanks Jim.
