Working on a friend's fast break in the left flipper will not stay energized or hold.
What would be the first thing to look at? I did check the flipper board and the fuse. Have you all experience it was the coil or maybe a transition on the board? Thanks for any of your opinions.

the only time I have had issues like this it was the EOS switch
Quoted from zacaj:Bad coil, bad connector, or bad transistor. Not EOS related.
Also check the power and hold in the flipper test
I thought the same when I had this issue, replaced coil and everything else except EOS. Was about to pull my hair out and finally replaced the EOS and it started working.

Coil or the hold transistor on the flipper board.
Quoted from 2manypins:I'm going to replace the coil first just to see
There is no reason to replace the coil. Simply measure it's resistance, comparing to the other flipper coil.
This is an NBAFB, right?
If so, then the power and hold drive transistors have been moved to the power/driver board. WPC-95 games don't have a separate FlipTronics board as in the past.
EOS switch is function immaterial. WPC FlipTronics and later flippers work even if the EOS switch is completely missing.
