Hello -

Backstory - I have a 1962 Gottlieb Tropic Isle that I am working on to bring the game into complete functionality. The main board has a counter installed, I believe this records the number of times the system was played. Discovered that the axle that the counter wheels rotate on was protruding out of the left side of the enclosure. Counter does not increment, guessing that the internal mechanism is not in alignment. Plan is to remove the counter, disassemble it, make whatever repairs are needed, bench test then reinstall.

Advice / coaching needed. Have any of you taken the counter apart to make repairs? If so, any warnings or tips tied to parts with springs or other?

Would rather do a repair than replace to keep the machine as original as possible.

Thanks in advance for your input

Eric

You're the first person I've heard giving the meter any interest at all, let alone a re-build, since it rarely indicates the machine's actual usage or condition. They usually count actual games played, but in the business, we re-wired to count coins instead.

I can appreciate your interest in originality but doubt anyone actually sells parts for the counter. Others, I'm sure will chime in if they're available but even so, I would purchase a used meter from one of my local EM buds and simply wire it in or in your case, use for parts. They should be dirt cheap. The step-up coil inside burning out was mostly the reason they failed, but that didn't happen often.

First jumper power to the counter to make sure it really is not working.

I was able to find a vintage replacement on eBay, good luck!

The "axle" was probably sticking out because either there's some broken parts inside (generally plastic pieces) or someone has tried to *repair* it. Heck, it might even have a burned up coil.

It's easier and cheaper to just buy a brand new 24 volt AC counter meter.

In post 91 of this thread https://pinside.com/pinball/forum/topic/gottlieb-spin-out-diary-of-a-resto/page/2#post-4419525 I refer to repair to a playmeter. Fairly easy to work on-I hope this may be of some help.

Thanks for the information. Time to hook up the DVM, do a voltage measurement to confirm the circuit has power. Will pull the meter out, see if its truly hosed up mechanically. If it is, the machine will get a new meter.

Right now, I am in the process of repainting the cabinet. Back box / head has been repainted, with webbing and new stencils plus I ordered and received a new glass insert.

Will start up a separate thread about the repaint effort.

Ive got three dead game counters on the bench, all have a broken post on the first reel not allowing it to increment. Did find a very small "new" game counter on ebay, $8 but it works off of 12v. 75 ohm internal resistance. I put a 75 ohm resister in series and it seems to work fine at 24 volts. It is tiny, about a 1/3 of the size as a regular EM game counter.

follow up and closure on this topic

Counter removed from the machine.
Using a DVM, confirmed that the relay providing voltage to the counter did cycle correctly and the counter would receive the count increment pulseo the
Disassembled the counter by removing the metal cover. Reseated and staked the counter shaft to the counter body.
verified counter would increment by applying power to the counter using a bench power supply set to 12V
Reassembled the counter, installed back in machine, verified operation.

Summary, this was a mechanical issue which was the result of the counter gear shaft separating from the counter housing. Did not impact the game operation. Thread may be closed
