Since it's an F-14 odds are one of the lock diverter coils in the top left is fried and is blowing the 50V fuse. These were wired to 50V on most F-14's when they should have been wired as 25V since they don't have a relay or a TIP36 turning them on.

If so you'll likely have to replace the melted coil and blown transistor(s) and possible a chip.

After that see this thread.

Put one lead of your meter on ground (corner screw of MPU board). Put the other lead on the metal tabs of the transistors. A shorted TIP102 will beep on the meter.

Quoted from TOKYOSANDBLASTER:

That was mentioned one other time. Ive soldiered in the past but I'm not sure I trust myself enough for this type of thing. If I was positive which wires to use I would probably try it. I've read that the red wire is supposed to come from the pop bumper?

Yours is already wired to the 25V from the factory. Some came this way. I just had an early sample F-14 late last year and it was wired 25V from the factory.

25V is the Red wire with the white stripe
50V is the Purple wire with the yellow stripe.

tried to repost OP's picture from post #47, didn't work.

Quoted from TOKYOSANDBLASTER:

Looks like it is the 50v wire[quoted image]

In that case the diverters have nothing to do with the blown fuse.
Normally on most F-14's the diverters wired up to the 50V is an issue and needs to be corrected.

The 50v from that fuse on yours is used to drive the Jagoff kicker and the 3 ball lock launchers and I think the top right VUK(all through relays) and maybe something else (the flippers are through the fuse on the 50V board (in the bottom left of that picture.)
