I recently acquired a 1964 Mustang by Chicago Coin. Game was in really good shape. Replaced bulbs and rubber and gave the PF a good cleaning and a wax. Game will reset with a coin or manually but after it resets nothing happens. The only thing on the PF that works are the 3 30 point targets and they only make the scoring motor spin... no bell... no points added. I can also manually trip the scoring relays in the head. When I do that I get bells and it adds points. Reset brings all the reels back to zero, kicks out a ball but then.... notta. Any ideas or help anyone can give me is appreciated. I do have a schematic for it and I can add pics or video if there is something specific that would help. Thanks in advance.

Thanks Howard... I'll find somewhere to get them scanned on Monday (hopefully). Meanwhile, I'm willing to try any ideas as well.

Game over lights briefly, as do most of the other lights on the backglass, but then it all goes dark... I'll see if I can post a video of it.

Here is the link to a video of the machine trying to startup:

Thank you.... What you are saying makes sense. I wish I could have run right out and started tinkering, but... Sadly I had to go to work. Haha

I am going to get the Schematic scanned in today and I will post it right away.

Meanwhile I will take a closer look at the Lock Relay. I do recall that it engages and then releases.... Seems like it could be the culprit.

Your help is much appreciated!

Got the schematic scanned in at Staples, Thanks @howardr

In looking at it I think you all have me on the right track. Looks like the Lock RE should be closed and I know for sure that it doesn't stay closed when I start a game. Can I test it by simply holding it closed and starting a game and if that works just replace the coil?

I had to shrink the schem a bit but I think it is still clear when you zoom in. Thanks again all!

Thanks HowardR I will give this a shot tonight and report back!

Wahoo! There is a switch that is mounted to the board on the bottom of the cabinet. Maybe a "cheat switch" it looks like maybe it should have a spring on it to keep the switch closed. For now I have it held with a little wood block. Anyone know how this is supposed to work?

Now I am totally in business! You guys had me o. The right track and it paid off. I just need you adjust the cheat switch, or leave it propped... either way I have a working pinball! Thanks guys!

Perfect... thanks everyone. I am going to mark this resolved. I'll be back if I have any other issues.
