Just like to mention that a 15A breaker would be best, but I have a 5A and 10A and actually
the 10A holds up in a 15A circuit as long as there's no problems in the circuitry.

Like pinballdavek said, as soon as the G.O. Relay resets, the fuse blows.
A couple/3 years back I went through a Bulls Eye Baseball that was problematic.
Chances are slim, but would you happen to be in Upstate N.Y.?

The 30V fuse is blowing, right? A shorted power cord would blow the 110V
I think I remember the fuse is blowing once the Game Over Relay gets reset at
start up, right? If there was a dead short in the Pitch Motor it would blow, but not
until the motor got energized. The Pitch Motor doesn't energize at start up.
I'm sure your pitch motor is fine. If the coils physically look okay, it could be
in a couple wires, or I even once found a short in two blades where the insulator
had failed. I wouldn't say recommended, but I elegator clipped and jumped the
fuse holder and was ready with the plug to unplug and started the machine and
as soon as a puff of smoked appeared, I unplugged and the puff of smoke would
be where the problem was. If it's a coil, the coil will smoke way before the wires.
I'm not recommending, (I have to say that or people will say I'm crazy, haha) but
just saying. I've worked on so many machines that it's nothing, but extra sets of
eyes is always a plus when watching. I'm just saying if all else fails.

Haha. Nothing like that unless you left the house. If you lived close by,
I'd stop over.
Yes, a 15A fuse is blowing, but that fuse has to be in the 30V circuit.
The coils run on 30V. The Relay Bank Coil may be 110V, but we know
it's not that..
I skipped and jumped back in. Where were the 2 shorts?
