My battery was inadvertantly hooked up backwards due to the dealer gving me the wron gone.. The fusible link that foes from the Soloneod to the Voltage reg burned next to I guess it's a fuseable link. How do you replace it or find out if it has been blown.

Re: Fusible Links on 1972 Ford F 250 PU
Follow the wire where you think the link may be, and and where the large bulge is, is where the link usually is, now the fuse is not usually non-replaceable, so you can go to a parts house and get an aftermarket fuse link that can easily be installed. take the voltage regulator with you and have it tested to insure it was not damaged. also check all fuses in the fuse box. and the link on the main wire on the back of the alternator.

You may have blown out a fusible link. They can be cut out and replaced. Look around the battery for a wire whose insulation looks partially melted, or bubbled out a bit. Fusible links act like fuses and burn out before further damage in the wiring circuits occur. They are located near the battery because they distribute power to different circuits. Today, maxi-fuses in power distribution boxes or centers have largely done away with fusible links.
Either the battery got hooked up backwards and there is a blown fuse or a burned fusible link, or you did not connect all the wires to the positive battery terminal (there should be three).
I'm sure that if it got hooked up backwards, you will know about it (there would have been lots of sparking going on).
If this is the case, check fuse #24 in the Power Distribution Center (20 Amp) in the engine compartment. If this fuse is good, it should have power on BOTH sides of the fuse when it is checked with a test lamp. If there is no power on either side, then the fusible link either did not get connected to the battery or is got fried. The fusible link itself is ORANGE and is a 20-Gauge fusible link.
It all depends on how lucky you are today. Connecting the battery backwards can destroy some high-dollar stuff. If you are really lucky, you will only have a blown fuse (or fuses). Check both of your main fuse blocks on the left side of the engine compartment,
One of the boxes is called the "Fusible Link" box and the other is called the "Engine Compartment Junction Block" (J/B) (See picture below).
Your main circuits are protected by the 40 Amp and 80 Amp fusible links in the Fusible Link box and the 120 Amp Alternator Fuse in the Junction Block. You will most likely find one or more of these fuses/fusible links blown.
I bet you saw some dramatic sparks when you hooked the jumpers up backwards!
The good news is that if your ignition switch was turned to the "off" position when this happened, the fix may be simpler and cheaper than you think. This car has one or more "fusible links" in its primary wiring. They may look like a thick piece of wire, but they act as super-fuses in the the case of large-scale power shorts and the like. Fusible links are typically in-line, so you won't see them in either your under-hood or under-dash fuse boxes. If you're lucky, you blew a fusible link right off the bat, saving the rest of your electrical system from serious harm.
If your ignition was turned to the "on" position when the battery was hooked up backwards, you have a more serious risk that you damaged your on-board computer. However, even if your computer were fried, your dome light, your hazard blinkers, and probably your headlights and turn signals (different circuit than the hazard lights, believe it or not, even though it's to the same bulbs) would continue to operate.
I'm going to recommend that you should check for one or more blown fusible links. Good luck!
You blew a fuse. Im guessing most likely culprit is a fusible link. try both sides of fusible links found by your battery. both sides should show your approximate battery voltage. check all fuses especially ones that show power regardless of the ignition switch being on or off.
Start by checking all of the fuses and all of the fusible link wires, and you will know a fusible link wire when you find one because they will stretch similar to a rubber band. Fusible link wires are usually located at the fuse/relay junction box in the engine compartment, or at the starter solenoid, or sometimes at the fire-wall. Also check the fuse/relay junction box for any PAL type of fusible links.
