Duster Roars but wont start...help !

The only place it says "3A" is in the one chart. That's what made me?? The diagram (which I did not post) and the fuse panel diagram (which I did, bottom photo) both say 6A. Frankly, I'd put a 10A in there.

I decided to scan the electrical diagrams and a few pertinent pages from the 74 diagram, working on it this morning. But yes, if you are "going to have" a 74, a shop manual would be wise. Don't know of a particularly good place, Efray is one, LOL
