Good Morning!

2 days ago I rescued this Grand Tour machine from a basement where it had been residing since the 80's and I have a electrical issue that has me baffled.

I need another pair of eyes, as I found a new problem while watching my son play test.

On the back glass is a list of numbered cities. As you open the Tour Gate and make the shot you are awarded 100 points and the cities light up and advance one at a time.

This all works.

If you should happen to light the number 10 city (Athens) you hit the EOS switch on the Advance Unit and the Advance Unit resets to the beginning. The Advance Unit Reset relay is activated, the Advance Unit Reset solenoid fires and the unit reels back to the city tour start.

Also good!

The problem is when the game is over and the game started the Advance unit does not reset to the begining. The Advance Reset Solenoid does not fire and of course the Advance Reset Relay does not pulse. I have looked close at the diagram and scoring motor and can't for the life of me figure out the problem.

Diagram is here if you want to take a look-

The documents clearly state the advance unit should reset on start. I have been looking for the past several hours without luck.

What say you? Contacts are are clean and set. I have inspected the jones plugs and all associated relays including start and reset relays.

The scoring motor has been cleaned and inspected and everything looks good there. I even went as far to slip an insulator between the contacts (2C-C) and during a gameplay advance unit reset it sent the scoring motor into a continues roll till I pulled it so the contacts are doing something.

I'm very comfortable with DC systems but I swear some of this AC stuff looks like greek to me! Williams diagrams are so much easy to read.

I'm baffled. This is my 4th EM and hardest yet to bring back... I'm not giving up.

Ok this is baffling- Looking at "Slide one" with the 2 red arrows you can clearly see the advance relay in the at rest position or normally closed for the circuit.

When the limit switch is hit (when you hit 10 cities) the circuit is complete and the advance unit reset relay fires and the advance unit reset solenoid is triggered and the advance wheel resets. This all functions perfect.

So if I'm reading this correct the unit only clears the cities if the city count exceeds 10 since the limit switch is the only thing the fires the relay. I'm baffled as it shows a NO contact for the advance unit reset relay going to itself on the right side?

I'm confused.

Hi gdonovan
ipdb has to every pin some text - http://www.ipdb.org/machine.cgi?id=1081 --- and when we click on a word "written in blue" we get to "Pinball Glossary". Click on "carry-over" and see: http://www.ipdb.org/glossary.php#Carry-over --- the feature carries over to the next game. Greetings Rolf

Never heard of such a thing! I'll be darned, been running around in circles for nothing!

If only I had an owners manual!

Thanks!

Hi gdonovan
You would like to have an manual --- chances are 99.999% there is NO manual. I recall https://pinside.com/pinball/forum/topic/bally-the-race-is-on-the-first-oldest-real-manual#post-2780232 --- and as well: https://pinside.com/pinball/forum/topic/capersville-the-best-em-rules-are-on-ipdb#post-3154935

I bet that Bally made (at the old times - arcade rooms) this feature as a "teaser feature" - OK, OK - I put in one more coin and GET me the reward ...

I actually would also like this feature to reset when we start a new game --- is it worth trying to do this "hack / modification" ? Greetings Rolf

I actually already tested a "hack" I connected the solenoid from the credit reel to the advance reset and when you pushed the start button it would drop the advance to beginning. Only problem was when you cleared the cities it would take one credit away. I bet with a relay or diode I could make it work but am satisfied if the machine is working as designed I'm all good.
