Got a Williams Jungle Drums almost for free, so this is my first EM game. I am more into the Video Games till now. My education is electronics but microprocessor based, so a whole new world I am entering. Luckily schematics and service manual are there and are beginning to make sense to me. What helps alot as well, are the EM repair guides from Marvin that are still found in the Internet Archives.

I don't have the room to take a decent picture of the cabinet, but someone decided to apply vinyl with a 'dark wood' pattern - awful. When removing th evinyl, almost 50% of the original painting came with it, though the artwork outline is still visible to be used as producing the masks for a re-paint. My focus is to get the game working and cleaned. Painting and restoring is thereafter.

Game was sort of partially working with some lamps and recognizing the coin entry. Also the score wheels were resetting to zero. But certain motors didn't turn and also 50VAC were missing at the trigger switch. Found the issue to be with the lock relay and bad contacts, cleaned contacts and here we go. Now the motors are working and I can shoot with hits being scored. But I can shoot only a couple of times. I think the shot (score) counter is the problem, movement is sort of tarish. I am in the process of cleaning and now waitiing for the recommended grease to arrive.

Unfortunately during separation of the unit one of the 'EM Style' female connectors broke. Any chance to buy a replacement? My search didn't reveal anything. Would need a 5x2 per attached picture.

For almost free it's a fantastic pick up. This is the first I've seen and I watch daily for games Craigs, eBay, and Mr. Pinball. So welcome to our EM addiction and once you have one, and restore it mechanically, furthermore cosmetically, you'll want more and more variety. It's where it all began and that's the beauty of it. Essentially an entire industry in the US that is now gone...mostly due to technology.

Regarding the female jones connectors. Stop looking online these are no longer manufactured. Occasionally they show up on ebay as a lot of used parts. However you can try to search the want ads of Mr. Pinball. I'll P.M. you with a gentlemens email address whom may have some female jones connectors. Don't want to broadcast his email.

The pinrepair guides are how many of us learned EM. Many, many arcades decided sometime in the late 70's early 80's to place vinyl over the artwork of these games as years in damp or cold storage cracked and peeled the paint. My 59' Midway Jokerball has that vinyl over art that I'll remove. These games in there entirety are a lost form of art.

Regarding the mechanical restoration. Since your electronically inclined always check your hold coils and I tend to check every coil with a multi meter. Hold coils are always on and after 30+ years even if they work to help you get the machine functioning - continual use will cause the game to malfunction as when they heat or overheat they buzz loud and don't function properly. These are available from Pinball Resourse for a reasonable price.

The score motor is another area of concern old techs oiled everything and I mean everything - brass gears, armatures, etc. As your confidence builds you may want to carefully tear that unit down and clean it. Especially if it's running sluggish.

That brings me to your point regarding grease. I would use very small amounts if at all. It only attracts the dirt you just cleaned off with 91% alcohol. Your stepper units are also something you'll learn to tear down carefully and clean all the glue (oil) off of. Again I suggest a magnetic tray for these parts as you want to lose none of them.

Good luck and welcome to our EM addiction...I'll send that email to you on PM later today...

Hey thanks for the warm welcome :)

Let me tell you that I have started to take the shoot counter apart already. There was a lever with their axles rusted. So removed that rust and added a little bit of grease there, that should be ok. More work to do for sure, but weekend is over now .... waiting for the next.
 
Sent you a private message with that email address...can't wait for the weekend either! However will be downstairs tonight trying to figure out the mystery of my Gottlieb Target Alpha...good luck!
 
Nice pickup. Get used to the idea of tearing down those stepper units, they tend to seize after 40 years. Not done a score motor yet, though. Pinrepair is an awesome place to get info. I also recommend getting a "parts catalog" for the year/series covering the game. It will show exploded views of the mechanisms used. They should be fairly cheap and mine has saved me many, many times.

That said, document EVERYTHING you do with this machine. Nothing worse than breaking your machine and having no idea how you got there. When tearing something down, take lots of pictures.

Finally, these games function on very simple logic. Most problems mechanical in nature. Enjoy!
 
Sorry got really busy. This one is out of an old six card. I sell these kind of connectors for $2 a pin male or female so you would be looking at $20 plus shipping. Let me know if you are interested. Sorry about the poor quality photos:

I used two sets of twelve when I crashed my CDI Skiball and they worked perfectly. They are a bit tighter so be careful connecting and disconnecting once installed. However worked like a charm. Looking forward to seeing some pics of this game...
