Finding electrical short

[Yukon Jack]

Driving my 69 home last night in a light drizzle it started to idle a little lower than usual. Idle was a little rough but not bad. As I came up to a light, I lost all electricity. Got out, opened the hood and see a little smoke coming from the fusible link off the + battery post going to the little black electrical block on the side of the fender.

A guy immediately stopped and pulled me over to a little used tire store in the not so good part of town. They had some fusible link but it started to burn as soon as it was attached.

My buddy with the 71 1 ton Chevy 4x4 came to drag my truck to my house, driving his . . . well, I'm so ashamed to say, his 1 ton Ford. I naturally fainted! When I came to I had sense enough to not want to leave my truck at this tire store over night for fear of it being stripped in the morning (oh, there was a adult book store right across the road speaking of stripped), so I let him drag me home with the Ford.

So, how do I go about finding the short? I'm electrically stupid, imagine that.

Is it best just to get it to an auto repair station and let them do it?
