Electrical system

[Redleg130]

This project is very tedious. Everything is a tremendous pain in the backside. It is worth doing as I am finding corroded, worn, and vulnerable items pretty much everywhere so its good that this system is getting attention.

Not electrical, but this has bugged me for awhile. The knock out for the winch lever is just open, and I can't find a cover for this. I made one from thick rubber, using a dremel to cut a deep groove in it so it holds, the backside has adhesive so it should hold.



The junction box from Amazon will likely work pretty well, its fairly sturdy and fits on the (I think) regulator mount. I did need a piece of sheet metal and generally my garage has a magical property of having bits of scrap that meet whatever need I have, but it took a bit for this one. I did end up cutting up an old washer/dryer cover plate for the sheet metal, which took awhile to shape but it will work.



With a place to connect the various wires, I can start actually wiring stuff up. I won't reuse any of this wire, but I am leaving it until I replace it so I have some reference for what connects to what. Replacements will be in loom, I started with key ignition set and am very happy with the protective wrap plus fabric tape combo



I did run into a snag, the starter solenoid post does not have enough room anymore and I am not sure what to do. The thicker battery cable is good but the alternator and two ring terminals need to go there too. One ring going to ignition via ballast and the other going to fuse box. Do they make a solenoid with a longer post?

Is there no kind of electrical terminal duplicator or splitter that will work? (Something like what you see on modern car battery terminals, where the main connection goes to the batter post, but the clamp also has one or two smaller terminals to piggyback other wires on it.)

I could try stuffing two cables into a larger ring terminal and crimping two in one maybe

A special nut is made for joining two pieces of 'ready-rod' or 'all-thread' in 5/16NC or 3/8NC thread.

Maybe use one of those, with the high current lugs on the first thread, and the others under a short cap screw.

You need one of theses. Mount it on the firewall where it's accessible. Move all wires but the battery wire to the new buss bar. Then run a 4ga wire from the starter terminal to the buss bar.

Or if trying to keep original looking, google stud extender.

Its Cortez burning his ships time.

Got the open questions open regarding what connects to what (which did match the wiring diagram unsurprisingly) but a couple parts like the foot dimmer didn't have markings so I did want to trace things like that. With the last bits mapped out, I was able to remove the last of the old wire.




Stud extender looks like exactly what I would prefer, thank you for the term. Busbar is a possibility too, but ill try stud extender first. Not knowing terms makes it hard to find things :v

I did get a wire wrapping loom with fabric tape and I am very happy with how that ends up, the bundles are padded a bit with it.

Thought I would show AF8 tool use, the 4 way crimper, on packard shells. This covers the 'male' end, ill post females later. This seems correct, based on looking at disassembled originals, but if there are errors, please do correct me.




The rubber shell goes on the wire first, followed by the white insert. The metal connector can only fit in one way to the white insert, ensure its oriented correctly before crimping. The more narrow end will face away from the crimp on the white insert.

the insulation should be against the metal connector with the exposed wire taking the entire space in the crimping area. You can see the wires poke through the other side if its long enough.
There are two sides to the metal connector, an end with an external sleeve at the top, and an end without this external sleeve. You can see the orientation in the first picture. This sleeve does not like going through the AF8 (4 way crimp) tool, but it will. I found it easier to insert the connector into the AF8, then the wire, that way I just have to wrestle it out in one direction instead of both ways. Crimping takes considerable oomph, but it does make a solid crimp.


When complete it will look like this


The completed connector


Making the tags - light taps are sufficient, too much hammer and it will weaken the tag


And wrapping them - I am surprised how easy it is to wrap these, and how sturdy they are when in place.


This set of connectors I assume are original, its interesting how durable these connections are. I was able to recover three out of four parking lights, the last one had screws so corroded they snapped even after overnight in penetrating oil. I found a replacement at Big Mikes for 70ish.


Started and ran the engine to get fluids moving, nothing but ignition key to ballast and coil are connected but its good to know at least that works. I still have a long way to go with the rest of the wires.
