help burnt wires on 270 gmc

[mog797]

Okay so here is the deal I have been spending a lot of time fixing and replacing wires in engine bay and under the dash. I have what would be basic stock setup 59 gmc with 270 my big question is with the generator and voltage regulator. On mine the black wire with white line runs from screw in the generator to a screw holding on the voltage regulator. When I tried to crank the engine yesterday it burned straight through. Dose anyone have pictures of their's both regulator and generator. I posted both of mine the way they were except for the faact that i replaced the blue wire with a yellow one same gauge it was handy. Thanks in advance yall
