More (self-inflicted?) Whodunnit issues. I did some much-needed work on my Power Driver Board and after re-installing it, I have no controlled lamps. Would someone please take pictures of the J133, J134, J135 connectors to make sure I have them connected properly (they are all keyed the same!!!!)? Also, J120 would be appreciated. Thanks in advance.

Quoted from alexmogil:

Previous owner seems to have used super glue.

Mine was like this in a few spots so i used 24 hour Araldite (you guys might have a different name for it over there), super glue is ok for some things but it has fairly poor shear strength. The repair may not look fantastic but it will hold and should sort your problem. Unfortunately for now that left ramp is unavailable as new

Thanks for the quick pics. I looked at mine and the wiring at J120 and J121 along with J133 and J134 are opposite of yours. I thought that was my problem but in looking at the schematic (and confirming with a DMM) they are keyed the same and are truly parallel connections (J133, J134 and J135 are triplets). Additionally, J137 and J138 are twins. Further investigation led to the discovery of no 18v on the power driver board. I had just replaced the header connector at J121 and all of the caps, including the 15,000 uf caps at C6 and C7, so I no doubt messed something up. Back to the workbench!

Quoted from alexmogil:

Anyway here's the left train exit. As you can see the plastic is broken on the left screw and the right screw is tightened way tight to keep the metal from moving. Tight enough that I'm afraid it might get damaged if I'm not careful. Previous owner seems to have used super glue.

W?D are notorious for this. Usually some washers will keep it intact but for plastic "Ambroid Pro Weld" is a common product used. There were a few spot on my W?D that needed it!

I messed up a through-hole on the + side when I removed C6. Put in a stitch and all is good. Thanks again for the pics.

I think I have a nos left (train) ramp somewhere. I will dig it out and let you know.

Let the bidding begin Think you'll find there's a bunch of people need one of those, including me

I just listed the main ramp. It's a little scuffed up but should polish up ok

My right reel isn’t sensing the opto. Any ideas? I’ve taken the “problem” opto board and tested on the left and center... it works on those reels fine.

Weird. Threw my hands up and put it all back together so I could just play... now all the reels work fine. Whatever works!

So nice to have freshly shopped playing 100%!

Might be cracked solder joints on the opto board and resetting it might have make a good connection. I know you put it back together which is a PITA to get back out, but it might be worth messing with if you ever run into it again.

This ^

Or also these, all of which I've experienced in some place or other:

Or also a tenuous break in a wire that is sometimes open, sometimes closed.
Or the flexible stuffed "pin" in the Molex connector isn't bent enough & isn't touching the PCB solidly all the time.
Or the flexible stuffed "pin" in the Molex connector isn't seated all the way & is pushed back slightly, so it isn't touching the PCB solidly all the time.

Having trouble with my reels matching the dmd. My right and left get a little off as the game goes on. Is this common? Motor and opto's check out. Actually replaced opto on right reel. Did the white electrical tape trick. Kinda scratching my head......any help is much appreciated.

Thank you

My center reel does that as well. Haven’t dug into it to see why yet. I believe there are several known issues with this, one being the way the reel connects to the rod. The reels are cheap plastic and crack there.

#167 67 days ago

I have had this happen when the wheel doesn't run true (wobbles) so the opto miscounts the opening it's supposed to see. Also the grub screws holding it in place are often over tightened and crack the plastic on the wheel so it becomes loose.

#168 65 days ago

I desperately want to see someone remake the center ramp. Mine is discolored and a brand new clea one would be awesome!

is there supposed to be a gate on the shooter lane exit?

Quoted from weaverj:

No...I wondered the same thing forever.
To much traffic during multiball. I assume the proto's had it. But i could see that breaking over time. Thus factory left it out. Also gives you a shooter lane save with it gone, but instant auto fire will happen.

#171 26 days ago

yeah, it is odd. tyvm.

fyi: just got one of these in a trade, so there may be more questions coming .

When shooting up the main ramp the ball often rejects and comes back down. I was wondering if there is any mods that anyone has done to the ramp top bar that reduces this happening?

There should be a gate at the top of the ramp that prevents the ball coming back down after it reaches a certain point. Maybe this part is missing on yours? I think this is the one.

Or maybe you have weak flippers? Could be time for a flipper rebuild.

Yep this must be it. No way the flippers could be that weak with the elevator being so close
