Exclamation electrical system failure in 94 s10 --HELP!!!

I have a 94 s10 4x4 with a 4.3, and recently, without any damage done to the truck, the turn signals, cruise control, brake lights, back up lights, and taillights quit working, one day they I started the truck and they were gone. I have checked the fuses and made sure the wiring is all connected, any ideas or similar experiences please say something! I am short on money and would like to know if this is something I can fix myse.lf

Check that the body is still grounded to the battery. Might have lost a ground strap...

fusable link went belly up. if you don't know what they are its a length of wire that acts as a fuse in line from the power supply under the hood. theres one on the start main cable and theres one or two on the alternator going int to the main harness, most likely the one on top burned out, if you put a test light in the wires coming out of the alt. see if you have any light, if you see the link its about 3-4 inches long and different color then the red main wire, gently try and stretch it, if it stretches then its junk. and a new one in its place or jumper it to see if everything comes back on. good luck

Can check at autozone.com, they usually have the wiring diagrams scanned in from chiltons manuals.

thanks for the suggestions, turns out I lost a ground strap to the frame under the bed. Hooked it back up, and problems solved.
