I crossed lines on my 1991 pathfinder. Battery is good but truck is getting no power whatsoever. What fuses would cause this, where are they located and can u check if they're good by just looking

I should also note that I noticed white smoke coming from the positive battery terminal cables. Could that be a problem? Another guy I talked to said it might not have made it to the fuses it something there blew first..? I should also note that I noticed white smoke coming from the positive battery terminal cables.

You may have a fusable link attached to the positive battery cable end. It will be a rubber like wire and may have melted apart. Inspect the positive cable for a fused link and if the insulation around it is melted. The wire may not appear broken but if you give it a gentle tug it will seperate if melted/broken internally. If you find this to be a problem, replace the link and retest for power You may have a fusable link attached to the positive battery cable end.

Could u tell by looking at these?

This appears to be the positive cable. From this picture, have a look at whats under the black plastic on the cable end I see in the picture. There may be a link/fuse there.

Also I lookked for the copper fuse around the relay box and found nothing. The main positive wire goes straight to the engine while the other wires with sockets go to the relay box. Don't know if that's relevant info. Also I lookked for the copper fuse around the relay box and found nothing.

OK.... Better picture. These wires coming from the battery cable look like fused links.They will have a softer texture than other type wiring. Grasp each wire in your hand and gently pull. If the wire/s stretch or pull apart, suspect a bad link. I will try my wiring diagram supplier to see if I can locate the location of fuses/links that may be pertenent to this issue and get back to you OK.... Better picture.

sounds good, thanks! i wont be back to the truck till tomorrow afternoon. but if those are the fusible links, and they are bad, would that mean everything else should be ok? it seems like if those blew the power wouldn't have gone any further. sounds good, thanks! i wont be back to the truck till tomorrow afternoon. but if those are the fusible links, and they are bad, would that mean everything else should be ok? it seems like if those blew the power wouldn't have gone any further.

All would power would stop at broken link, thus protecting other circuits All would power would stop at broken link, thus protecting other circuits

great, all the replacements im finding online line have 4 wires instead of 3 or 2 like the ones in the picture. will that be a problem? great, all the replacements im finding online line have 4 wires instead of 3 or 2 like the ones in the picture. will that be a problem?

You can just go to an auto supply store and get a small length of fused link wire ( I would recommend 12-14 gauge ) and cut the old piece out and wire a new piece in if a bad link is found.

so is that as easy as just ripping the bad wire out and stuffing the new one in? so is that as easy as just ripping the bad wire out and stuffing the new one in?

If you find a bad link just wire a piece of new link in. You can bypass the plug altogether. As long as a new piece is wired in, it doesn't have to look pretty or be complicated.

could i even snip of the burnt piece and twist up the same wire? could i even snip of the burnt piece and twist up the same wire?

Yes.... If re moving the bad section leaves you enough to do so. Usually there will not be enough to reattach and a piece will have to be added in Yes.... If re moving the bad section leaves you enough to do so. Usually there will not be enough to reattach and a piece will have to be added in

cool! i almost wanna go work on it in the dark tonight, but ill let you how it goes, thanks for the help! cool! i almost wanna go work on it in the dark tonight, but ill let you how it goes, thanks for the help!
