Flipper problem

[ajlaird]

Coil might still be good - try to remove the sleeve. If you can install a new coil sleeve - the coil might be ok.. If you cannot move the coil sleeve, then discard the coil. Might be worth checking the coil with a multimeter - a diode is cheaper !

OK, didn't know these things had sleeves - the coil itself is almost for sure still fine as until I checked how hot it was and decided to turn off the pin for a while it was still firing at full power.

I will grab a new sleeve from somewhere (depends where I go on the lunch break) and make sure EOS is working as it should - I reckon this got knocked out of alignment in the move. And I will monitor coil heat to make sure there are no other issues.

I did see the machine a couple of weeks ago and I commented on it's rarity and it's immaculate condition. Certainly, you are very fortunate to have such an awesome machine...

 

Now lets get this flipper going !!

Unfortunately it looks like I have stuffed the sleeve - how do you normally get a sleeve out??

Couple of ways of doing this.. First of all - Does it move at all ?

When they don't move, you need to break the sleeve. What I do, is use a tool which is a long thin screwdriver - Just push the screwdriver inbetween the coil and the sleeve and "break" the sleeve. Move the tool or screwdriver along the sleeve until it has completely collapsed.... Remove the sleeve..

When installing the new sleeve, if you feel resistance, just spray a little bit of Nifti on the foil sleeve and try again. If you cannot push the sleeve into the coil, then the coil is no good.

Not the Nifti again? it's like windex for pimples huh?

Also great for Gravel Rash !

Got half the sleeve out! Now for the other half.

OK, got about 2/3rds of the sleeve out with the help of some side-cutters and a screwdriver. What's left in there looks really melted on.

I think I will get a new coil and maybe work away at this one later. I might be able to file what's left of the sleeve down, but I am not that patient right now.

Remember you also have to be wary of the fact that "something" caused the flipper to "meltdown" in the first place.. you really need to work on that.

Well, my guess is no EOS combined with 3A slow-blow but I will test later tonight.

Revert back to the correct rated fuse, adjust the EOS, install a new coil sleeve.

Enjoy your pinball !

Deferred until tomorrow night - having too much fun with Dirty Harry.

OK have coil. My understanding of how these things should be wired:

Main power goes to common lug (outside)
GND goes to opposite outside lug
EOS - one end goes to centre lug, the other to GND lug

How does that sound? (And what colours are normally used to designate GND and power - 1989 Bally?)

[ajlaird]

I guess I wired it up correctly - it works and EOS works and coil is not getting hot anymore. Just got to sort out how it goes back together mechanically so that it works 100%; it is a bit different to the LHS.

Good news - well done !
