I just did a rebuild of 2 (out of 3 flips) on my whirlwind.
The left one keeps on heating up and loses power and already blew up 2 fuses.
The coil has 5.2ohm and gets 68V
When on or in game mode without playing it's not heating up.
Everything is new, coil, eos, coil stop, sleeve, capacitor (already had to change one coil sleeve as it blocked pass through of the plunger)
suggestions ?

Quoted from chad:

Is your end of stroke switch opening up fully with flipper up.?

Yep it is about 3mm

Quoted from LTG:

Is the coil wired right ?
LTG : )

Yes, back as they were originally

middle black one to the long end of EOS, other black one to the short end of EOS.
yellow/grey cable should be at diode side with the line on.

pics of the new eos, looks ok, just cleaned them with isopropyl acohol
still have to check resistance. In what mode should this be done (off /on /on in game ?)

cables before rebuild (after rebuild post 5).
As you can see I switched the direction of the coil according to VID's tips

Quoted from mbwalker:

Should there be an insulator here? Can't be sure from the picture. You could check the other flipper that is working correctly. Or if it is there, is it worn through?
If I'm not mistaken, the flange needs to be isolated from the leaf switch, otherwise it grounds the leaf switch.

There is a kind of rubber around both plunger cranks (left & right)

Swapped the coil for a new one (while it was a new I used initially at rebuild)
Did a resoldering of the EOS and put some tape around and problem is now solved.
Before resoldering I did a check but nothing was short or touching each other...
So it simply might be the coil having an issue ??
