Hoping for a fresh set of eyes on this one.

I traded my buddy a Radical that was playing totally fine at my house. We moved the game to his house and after about 25 games the F6 fuse on the auxiliary driver board started blowing. After some trouble shooting we determined that after a few presses on the left flipper the fuse would blow. We cut the power to the upper left flipper coil and the problem went away, so we are pretty sure the problem is isolates to that flippper/mech.

We replaced the coil just to rule that out and the fuse still blows. We pulled the whole thing apart and have quadruple checked for shorts at this point but nothing is obvious. The game was playing with no issues prior to moving it so the flipper wiring is correct.

The only other variables I can think of are the EOS and the cabinet switch. None of these seem to be shorting but I guess could be bad? Caps on either switch? Just wanted to throw it out there and see if there were any thoughts on what to check that maybe we haven't. Thanks!

The coil reads the same as the others. If we replace the fuse, it will temporarily work again - sometimes just a few flips and some times a full game. It also looks like the EOS is opening as it should but we did notice the mounting plate and hardware for the flipper doesn't appear to be original and was probably replaced by an operator at some point...
