So I've got Jim's non-working, but cosmetically decent T2 in my pin lab (aka garage). I haven't had a chance to play around with it too much this weekend but I'll list out here the list of current issues, and my progress. It would be greatly appreciated if more experienced pinheads would chime in with their thoughts.

Running list of issues:
  • None of the solenoids work, I haven't checked all the fuses yet but I think F112 is blown, and it supposedly blows every time you start a game.
  • The left flipper is stuck, can't even move it manually. Time to do a flipper rebuild?
  • When I start a game, the cannon will move while I hold down the flipper buttons... weird!
  • The right flipper is not a WMS flipper, looks like a Stern flipper. Are these the same length? Looks a bit off to me.
  • I noticed some grease on the plunger used for moving the ball from the trough to the plunger.
  • HK ship is missing, and there's a crack on the T-800 skull. Marcospecialties has both in stock, will probably only order the HK ship.
  • Two of the tree standup targets just below the pop bumpers are white instead of red.


Question: Why does the manual say that F112 is 5A, SB when Clay's guide, and other references to WPC online says it is 7A? Is T2 special? Or is it an error in the manual?

Ok, so I put in a 7A fuse into F112, despite the manual saying 5A. So far so good!

The machine starts up ok, and the solenoids work!

Only problem: If you hit the left flipper, F112 blows. I figure I'll need to do a flipper rebuild, since the left flipper is completely seized. Or should I just buy a new coil?

Also, the sticky grease on the ball feeder coil is causing trouble. The machine tries over and over to knock the ball into the plunger lane, but since it's slowed by the grease, it can't quite seem to get it out. Once I manually get the first ball out, the other 2 come out just fine during multiball. I tried cleaning the plunger and sleeve using some dish soap (hey, it claims to cut through grease), but it didn't seem to help much. Should I buy a new sleeve and plunger? Or just a new sleeve?

What do you mean when you say the left flipper is seized? The plunger won't move inside the coil at all?

My guess is that your coil has shorted out and expanded internally. This would explain why the fuse blows and why the flipper is seized. You'll need a new coil and sleeve and possibly a new plunger & link as well. A rebuild kit would include everything you need except the coil. If you want to go the overkill route, there's always THIS.

cooke: Yup, the plunger cannot move. Thanks for confirming that the problem can be fixed with a new flipper assembly  and coil!

I ordered a flipper rebuild kit, as well as a red flipper coil from pinballlife.com

That kit you linked to is for game 'after' T2, so it's a no go for me. Plus, if I replace one flipper, I should do the other, so that they feel the same. No?

Right. Forgot that Fliptronic didn't come along until after T2.

Yes. If you rebuild one flipper, you may as well rebuild the other.

Typically, there should be no grease in coil sleeves/plungers.
After cleaning, check if the plunger is mushroomed at the bottom end.
If not, and if not pitted, then it should be OK to keep.

Also check if the coil brackets are held correctly by screws.
I have seen that if a screw is missing, the coil assy could go misaligned,
causing binding of the plunger.

You might need to replace the sleeve and/or return spring
if the above checks are not helping.

Cheers,
- Sylvain.

I have also had my flipper seize up as described twice.  Once it turned out that one of the black hex machine screws was not installed and therefore the whole thing became misaligned and 'jammed' as Sylvain described.  Also I am not sure I had the 'backplate' or whatever it is, the stopper plate, I don't think it was set in properly (the black machine screws hold it in place).  

My T-2 has the orange coils installed (a step up from Red) when I first got the machine.  I put red in, and found that I think i preferred the orange.  T-2 plays much better with the stronger coils, but I was afraid to damage any plastics.  It would almost be better to have a coil strength just a tad stronger than the red but not quite as strong as the orange for the T-2.  Just my opinion.

The other time, my coil shorted and got super hot, and caused the sleeve to melt and locked up the plunger.  

And for the love of Pete, DO NOT forget to put that spring on that goes over the plunger on the non-fliptronics when you rebuild it.  That weak a** spring actually serves a purpose by helping return the plunger to the reset position after you release the flipper button.  

In regard to the ball not getting kicked out into the shooter lane, are you sure that the sheet metal just above the area where the ball comes out isn't perhaps bent down too close to the hole, preventing it from coming out easily?  I think the piece above is angled like '/' if I'm not mistaken, but I'd have to look at my T-2 when I get home to see.  When I first got my machine, the metal was bent a little bit too close to the hole, actually causing a problem with the ball coming out.  That was my first problem, the next was the wrong coil in the spot that shoots the ball from the return hole, down the trough to be ready for play.  Also perhaps the coil that permits the ball may be dying on you?

The coil bracket is properly screwed in, and the plunger doesn't seem mushroomed. I guess I should wait until my replacement coil sleeve arrives. In the meantime, I tried a coil sleeve from a kickout hole, but it didn't fix the problem, but then again, it looked pretty worn too.

As for the left flipper, I looked into it last night and as I feared, it's melted on the inside. I guess there was a short, causing the sleeve to melt.

I also noticed that my right flipper has a blue coil. Too bad I already put in my parts order, where I included a red coil for the left flipper. I guess I could always do another order, but boy, those shipping costs are KILLER. We need a Canadian pin parts dealer.

Firehawk: I'll take a look at the metal over the trough that you mentioned. I can compare it with my white water.

What is the number of the coil you need? If they're FL-11630, I can likely provide you with one.

Yup, that's the red coil. If you could hook me up, it'd be appreciated!

My order from PBL arrived yesterday and just had enough time to replace the busted left flipper coil, and replace the sleeve for the trough-lane kicker.

The flipper now works! No more blowing fuses Unfortunately, after playing for a few minutes, the left flipper started to droop. Good thing I got a flipper rebuild kit from PBL Will do a rebuild on both flippers sometime this weekend.

The kicker though, not much of a success. Despite replacing the coil sleeve, the kicker still can't get the ball into the plunger lane. What could be going wrong? If I only have one ball in the machine/trough, it works for some reason, but then I can't do multiball.

Also, I never mentioned that most of the GI lights don't work. By most, I mean none except for the CPU light in the middle. I checked all the GI fuses, and saw a couple that looked to be the wrong type, so replaced them. Still no luck. I also checked a few of the bulbs by doing a continuity test on them out of socket (I assume that is reliable). Any ideas?

Your left flipper is probably droopy because you didn't tighten the pawl enough around the flipper shaft.

Are you sure you have the correct coil on the ball trough?
