P80 positivebattery cable 9456836 NLA , OPTIONS?

If you have a west marine store nearby, you can buy quality grade lugs, Ancor primary wire, and use their swaging tool in house to make the connections

A heavy duty truck supply store should have the same type cables, lugs and crimper if you are not near the water.

I have a swaging tool and have fabricated large gauge battery and power supply cables, but the issue with the B+ wire to the fuse bus shows up with all the twists and turns it has to make on the P80s to wind its way around the airbox and under all the stuff in the way. My presumption is that is the reason for the multi-wire arrangement the factory used. Trying to get a 4 gauge battery cable to make that trip can be a chore. I'm looking into fine strand welding cable or some such.

I had planned to pull the +ve battery cable for experiments from a 98 S70 yesterday, but the guy with the loader wanted me out of the way to get the car to crush it, so I didn't get the cable from it. I pulled on instead from a 97 850 NA. I noticed there is a smaller attached red lead that ran along with the main cable inside the harness and I believe may have run on beyond the starter. I don't see that on the later cars, and due to lack of time I just cut it, as getting anything out of that main harness cover is a bear, especially at -6C after being there for over an hour!

I'm now curious what that cable was for? Does it run to the alternator perhaps or is it an non-standard add in?

That B+ cable is basically never an issue on 850s, but a nagging headache on 98-00. Any ideas why?

[scot850]

It is definitely a lesser issue on 850's. 850's don't have the kidney shaped fuse box maybe something in that? Also 99-00 have larger alternators. 120A v's 100A. So wiring takes a higher load?

850 extra wire +ve wire

This is the extra wire that was attached through the main harness with the battery +ve cable. As it was taped to the main +ve cable was this an original feature on an 850?

I dont think my 96 850 has the extra wire, but I'd have to double check to be sure. I'm at work right now.

It was so nice out a few days ago I was considering taking the 850 for a drive, but then realized it's only February and we likely will have more snow. Sure enough I woke up to snow today.

I keep looking at it wanting to drive it.

I bought one of those pre made battery cables from a part store, with a top post clamp on one side and ring on the other in the same or larger gauge than stock and about the same length, ran the wire down to Smythe starter, tied the old battery cables away and kept the old cable in the harness. The wires that went to the fuse box I just put on the stud used to clamp the new top post end on. Been working great for 3 years so far. My issue was not getting full voltage to my battery while running, and cranking like the battery was dead when it wasn't, but no issues since. I think my running voltage at my battery is 0.5V higher now.
