Shelly,
In my years as a pro "automotive accessory technician", I have had to troubleshoot nearly identical situations a few times. It is most likely that when replacing the transmission pan or a bracket that was removed to drain it, a wire got pinched underneath an edge. This would likely be in that corner that is hard to see/reach. The exhaust system could also have done the same thing if any parts were unbolted to get at the tranny, or any wiring has been removed from the harness fasteners and is touching the exhaust pipe.(The hot pipe melts the insulation and the inner wire then touches the exhaust pipe and shorts to ground through the engine block and frame)
Take it to a shop and ask them to put it up on a lift so you can really have a good look around the transmission and exhaust. They will probably have a high powered halogen-type work light you can use, and they probably won't charge anything BUT I strongly recommend that you give them 20 bucks for the bay time.
Once you find it, either loosen the part enough to get the wire out, or cut the wire flush at both sides and splice it with a silicone treated waterproof crimp but(spelled with 2 t's, but fixya's censor program says that is a profane word) connector. If it was touching the exhaust and the insulation is burned off, wrap it with several layers of electrical tape and secure it to the frame or otherwise away from the exhaust with zip ties or wire fasteners. Good luck! Brian D. Smith

    And a BTW: Very few(if any) vehicles have any kind of fuse between the battery and starter. Under certain conditions, starting current may approach 1000 amps. A fuse of this capacity would not be much different than the battery cables and only blow if they were melting. "Main fuse" refers to one between the battery and fuse box/ignition switch. This can also be a FUSIBLE LINK. Good hunting!

SOURCE: 2000 isuzu trooper main fuse keeps blowing and

The main fuse usually only goes between the battery and the starter and the alternator. I'd bet the starter wire insulation is cut through by one of the wire ties or at the starter. If the wire got hot , which if it's blowing a 50a fuse , it did, check any heavy gage wires coming from that fuse to the batt and starter and alternator

2001 Isuzu Trooper No dash lights keeps blowing fuses


If you keep blowing fuses, you have a short somewhere in your wiring system. The ONLY way to fix this is to trace ALL your wires, and find the one that is grounding itself out by not having any insulation around it. Which means you can see the wire itself. Hope this helps, James Booth. Please rate this. :)

Turn signal/backup light fuse C-3 blows frequently on 1994 Trooper


The fuse should be around 15 amps, anything less than this will probably blow with any type of surge. The reason for a fuse of the correct value blowing is a short circuit in the system. Look for wires chaffed through, especially where the wire passes through body work and through supporting loops. Check the bulb holders that there are no loose or bare wires there. Other than that it is a long slow process of inspection and checking. Do not try replace the fuse with one of a substantially higher value, you could burn out wiring and harnesses - or the whole vehicle.

I just came across this same problem with an 02 Trooper. The problem was the pump itself. There are upgraded pumps available now. Your transmission shop should be able to get it.
