On the later 760s, with the fuse panel at the left side of the instrument panel, the fuel pump fuse location of the fuse panel can become discolored/melted: to the point that the fuse can fall out, or the terminals behind the fuse can fall off the fuse....a no run condition results.

Many assume that the problem is caused by the fuel pumps: drawing excessive current. That can be the cause; but not always. Some assume that the fuse panel itself must be made of inferior material which cannot handle the heat that normally occurs in a mid to high steady ampere draw circuit. There may be some validity to that assumption, but I rather doubt that.

The one cause for excessive ampere draw through the fuel pump circuit that is usually not addressed, or even recognized, has nothing to do with the fuse panel or the fuel pumps. The cause of the excessive ampere draw can be found at the battery. It is what is called the "Positive Terminal".

In the 760 wiring diagram green manuals, it is identified as item "15"; and the illustrations of item #15 show the junction strip/box that I actually did install [shown in this image]. In the 740 wiring diagram green manuals, it is identified as item 29, using the same 'incorrect' drawn image.

This supposed "Positive Terminal" is actually a crimped junction of three or four wires, that are then connected to the battery postive post terminal via a short piece of [approximately] 8 gauge wire.

Not only is an incorrect drawing used as the illustrating image of the "Positive Terminal", but the places where the green manuals say that that wrongly illustrated thing is located are also incorrect. Try finding what the green manuals show as the Positive Terminal, and in the locations the manuals give, and you will waste a LOT of time trying to find something that is not there.

This image is what I did to correct the problem on a 1990 765T. I added in a primary junction strip/box from an older 240, to replace the well corroded OE "Positive Terminal". Now, that wagon HAS a real "Positive Terminal #15"; and it is where it is supposed to be; but in a better spot.

When I get a chance, I will add a pic of a corroded OE Positive Terminal. And complete the explanation.
