left flipper rebuild - failed at! help please

[cmrl9]

Hi,
So I have tried to rebuild the left flipper, I bought a rebuild kit from pniball heaven.

I have fitted the flipper, however when I turn the machine on nothing happens on the left flipper. Have I soldered the wire wrong? They are in the correct place.

 

[cmrl9]

Original Flipper Coil, from a previous question I believe is incorrect.

 

[cmrl9]

New flipper

 

[cmrl9]

BE gentle, my first ever attempt with a soldering iron, how are the wires suppossed to go, are the suppossed to touch the holes with the transistor and wore to the coil?

 

[cmrl9]

Mine are not

 

[Andy_B]

Mine are not

Ideally the wires are connected to the lugs but it doesn't matter if they are attached to the holes as it's all the same circuit.[emoji846]

looks like you have got the wires on the ends the wrong way round.

Grey wire goes on the banded end of the diode
Orange wire goes on the unbanned end of the diode
You may have damaged the diode s on the coil so worth checking them before swapping them over probably blown the fuse too

Hi guys, thanks, a couple of quick questions:

Grey wire goes on the banded end of the diode
Orange wire goes on the unbanned end of the diode
You may have damaged the diode s on the coil so worth checking them before swapping them over probably blown the fuse too

I have the original fitted coil that worked but would hold up. The wires I put back in the same place, where they incorrect? It was working for number of months.

The fuses appear fine

I noticed the end of the flipper holding part is touching the brass end of stroke switch is this normal, my new right flippers not.

 

[cmrl9]

Before I attempt to de-solder I have a right flipper to put on. Sould the wire be bent round the conector? I have an old piece of wire and wil ltry and show what I mean in the picture

Yep the fuse is blown

 

[cmrl9]

Fuse blown, which wire goes on which. J907 has Blue and Grey wires.

Hi ChrisBPinball,

The banded end is that the grey circle around the diode?

For future reference should the banded end wire I believe the far left be plugged into the end thats going into J907 or J902 (top left of fliptronic board)

I'm not sure what the Lower left and Upper on the Flipper coil circuts Flipper circuit diagram means in relation to the coil. Does it mean the coil wire for the base of the coil and the coil wire for the top of the coil?

I just had to try explain why i think you made the mistake as it was screaming at me, but so easy to do!!
when you rebuilt the flipper you fitted the new coil with the solder tabs in the traditional way at the plunger end, the original coil was mounted with the solder lugs at the coil stop end, so you re soldered the wires in there original orientation but the coil has now turned 180 degrees so the orange and gray wires are now on the wrong lugs.

Do what Chris B said above and you should be all good again.

if when the meter is on diode mode it reads 0 or very close to it, the diode is dead and need to be replaced (taking care the diode band is the same end when you fit it). anything above 0.450 (red lead on the non-banded end) should be ok, check by putting the meter leads on the diode both ways round to confirm it

if you have another coil to fit on the other side, then compare the readings on your meter from both and in all meter probe orientations as a double check if your not sure or unfamiliar with what readings you should be seeing on it?

 

[cmrl9]

From looking the right flipper I understand now.

What's thrown me was the wires where soldered back into the same place, perhaps because it was the wrong coil this is why it worked?

 

[cmrl9]

Don't currently have a metre reader, its on back order with pinball heaven, is it safe to swap the wires round, im guesing it won't work!

Still don't get it regarding the old coil, Im tired but now I know to look at the banding, hopefully won't get cuaght out again

 

[Fishbulb]

Until you know the state of the diodes on the suspect coil i would not refit it as you will at just blow the fuse again,

on the yellow original coil the solder lugs are at the very end of the (plunger stop end)



on your new blue coil you fitted it with those lugs next to the flipper crank arm, or the other way around

 

[cmrl9]

ah I see.

Ah I see thanks.

Swapped the wire round now working.

Yep I had, doh working now

 

[cmrl9]

although the original problem is back, left flipper won't hold! but no longer double tapping

Is the end of stroke switch the right way round? I am not sure which way they should be on the more modern machines [emoji3]

No - this is correct.

I have noticed the o/p has started another thread about his issue. Which is may be an idea to close this one mods....

STTNG Left flipper hold problem! Still despite replacing the flipper to the correct one, Please Help

Hi, I previously posted a thread for some help with a left flipper hold problem. It was identified by members that the wrong coil was fitted, it appeared to be a Data east coil. This evening I have replaced the coil for a correct Williams one, after a rookie error of putting the wires on the...

It is confussing when people do that.

Machine is now permanently switched off, until the meter arives from Pinballl Heaven, this is very helpful, thanks
