Zeke's Peak TECH

[tomdotcom]

Good theory the bar is all the way down so it won't go down any farther and those down transistors test fine. I'll swap the wires and test it that way and report right back

I'll check the diodes as well.

 

[tomdotcom]

Diode test:

d1 1.3
d2 1.3

d8 2.7
d9 1.3

Diode resistance test:

d1 613
d2 608

d8 564
d9 603

Maybe I just need to replace that d8 diode? It's on the same circuit as q11 and q19. Could that be causing my issues?

Power Supply bridge test

BR1
1.03 red on - and black to +
.517 red on ac and black to +


BR2
1.09 red on - and black to +
.54 red on ac and black to +

Ok I replaced the diode at d8 but now I get 0 reading from it...think I made it worse. God damn it...

 

[tomdotcom]

I also tested the motor with a 9volt battery and the motor worked fine. I think I may just send the board in for repair. I messed up one of the through holes for the diode when I was replacing it...

To test the suspect motor just hook it up to the side that is working. The other side does not need to be installed. Make sure the limit switch on that side is open so it will run the motor on startup. In other words, lift the bar up a little on that side. You can also throw 9-12vdc on the motor if you want to bench test it to verify its working.
Let me pull the schematics up and see if I can give you any more advice.

I just tested it with a 9volt battery and it seems to work fine.

I may just send the PCB board and power supply board for repair. I replaced the diode at D8 and managed to screw up the through hole. For the life of me I couldnt get the solder out of the hole and ended up pulling off the through hole in the board. I love to learn and work on it but I think I may opt to spend some cash and have it repaired before I do any more damage ahaha...

Success!! Zeke's finally works! After many headaches and repairs (including some board repair by Riptor) and some new motors, and wiring issues, the game is alive!

Thanks anyone who helped, and special thx goes to Riptor (http://www.pacmandotcom.com/) for assisting with board repair and like 20 emails back and forth!

I'm VERY happy!

Now onto BSD!

One last issue to sort out. The lights that light up to tell you what hole to go to next don't work, even with new bulbs in all of them. Hopefully it's just a loose connection or something. Once I can figure that out, it will be 100 percent hopefully forever!!

 

[Riptor]

Are the lights working in demo mode? In other words, boot the machine up and let it run. It should strobe through all the lights. Those were all functioning so I know its not a board issue.

 

[tomdotcom]

Haven't looked into it to far yet. I installed new coin door lights as well, and they worked at first, but after a little while they went completely out as well. The only light that works right now is the top marquee light and the display works.

None of the 44type bulbs work at all, even in demo mode.

Least I can play the damn thing, you just have to remember what hole your on. But I do want to get the lights sorted out of course.

 

[tomdotcom]

I took a look at the manual and I installed the wrong bulbs in the coin door from the looks of it. They are supposed to be 12v 150ma pilot lamps? I installed 44's and they got cooked. The playfield lamps are all 6v so they would be on a different line. Could this have caused the rest of the lamps to stop working too?

I'm trying to decipher the schematic to figure out what exactly controls all the playfield lamps. Can't quite figure it out yet.

Tested all the fuses just in case and they're all good.

If you look at the schematic at hole 1 for example, it goes to D1 and then down to p2-t.

What is d1 and p2-t?

6v comes in through c9.

Hopefully this is something easy this time haha.

Anyone got any advice?

 

[tomdotcom]

I might be looking to far into it, maybe I just have a loose connection or something..

ULN2003, there are a bunch of them on the pcb. They do fail and your lights wont work. Since I just repaired and tested your pcb and the lights were all working I would say you have a wiring problem. Besides, if one of the 2003's fail you wouldnt loose all the lights. If you have one playfield lamp thats not working you can look at the schematic and see which 2003 is the culprit. I fixed a board last week that had two of them bad and my personal machine had one bad so they do fail pretty often from what I have seen.
Did you ever inspect the edge connectors? The pins have a tendency to flatten out in the connector. Sometimes you can pry them back out and get them to work but you have to be careful.

 

[tomdotcom]

I think I figured it out. The transformer wires that got snipped during transit are the culprit. I used one of this plastic quick joiners. The ones you just press down by hand to splice the wires. So I'm going to solder them properly and heat srink them and life will be good.

Thanks again, for the 12th time haha

Zeke's Peak is 100 percent! Lights work, motors work, limit switches are adjusted, bar is cleaned and lubed, pulleys are lubed, now who wants to buy it? Hahaha, I at least need to get to hole 10 before that ever happens
