I crimped and soldered my 2 wires together...

Hoping this thread still gets a read from time to time....

I'm finally getting to this project and have a question. Has anyone used (or see a problem with using) one of the 4 threaded inserts that are already in place on the passenger side fender as the grounding bolt location? I'm not sure what was bolted in place with the factory set up, but these are not used in mine and seem like a good place.

I thought I'd get a 2.5" brass bolt, that matches this size/thread count, and thread it in from the underside, throw on a washer and bolt on the top and ground away.....

Thoughts?

Incredible information. I am new to Jeeping, especially electrical work, and I am learning so much! Thanks to everyone (especially JH) for sharing all your knowledge and experiences!!!!

I agree that this ought to be a sticky, not only here but in ALL automotive/marine forums. Thanks so much for your insights JeepHammer!


Question, for smaller gauge wiring (stereo, amps, lights, etc) that welding wire is not gauged down to AWG is the 'go to' over SAE nicht var?
Pardon my ignorance, over the years I've been using whatever wiring was at hand, and while failures have been at a minimum, I feel that when I'm wiring up new gear or replacing/upgrading, I'd like to stick with the idiom in the original posts.

Hi JeepHammer and all,
I'm sorry to bother your with this and I'm sure you're getting innundated with questions but I hope you'll have time for this one. From the thread Basic Wiring 101;


THIS IS A 'FACTORY CRIMP' Tool, A 'Cheap' version from 'Radio Shack', and it will reproduce the factor crimps on connectors with 'Tails' that dig into both the wire and the insulation.

It's REALLY handy for a guy building a harness from scratch that DOES NOT want those big, ugly, failure prone crimps from the color coded insulated terminals everyone is so fond of...

These Jaws provide that 'Factory Crimp' that we are looking for"

Despite working in a college town, this damm place is a consumer desert when it comes to things like this. I'm doing a great deal of wiring and I like the idea of 'factory style crimps' but getting the tool locally is a real challenge. I found one made by Titan (made in Taiwan) that seems a little cheesy, stopped by the Rat Shack and, being more of a phone store than the former electrical/electronics store (that was managed by a veteran Navy electrician) and the staff had no idea of what I was talking about. Would anyone have a Radio Shack pn. for those crimpers? Thanks a heap and a lift of the lynch lid.

Gus

Well nutz, was hoping for anyone's response by now as there's an EBay auction for the last one of these and I think the jaws are what I'm after, I hope. Had to trip the trgger on this 'cause they were going fast and this was the en of the line. No one in this consumer desert even remotely had one even similar to this one.

Marine, especially salt water marine, is an ENTIRELY DIFFERENT ANIMAL that automotive wiring...
With marine wiring, you have to consider the ever present danger of fuel vapors (Fire/Explosions) and the corrosive effects of salt water.

Where I closer to the ocean, and building a Jeep, The rules would be RADICALLY DIFFERENT!

UNCOATED COPPER IN SALT WATER IS DEAD IN HOURS. NO EXCEPTIONS.
Just salt air can ruin a perfectly good land locked wiring job in days.

COATED or 'TINNED' wire is MANDATORY,
So are weather proof terminals, drip loops, explosion proof junction boxes, ect.
My boat days were frustrating to say the least, since I *Thought* I had a grip on wiring...
Entirely new learning process and a STEEP LEARNING CURVE since if it fails, you are ALWAYS out to sea somewhere... Hard to 'Walk Home' from there without getting REALLY WET!
I can see why the guys that do a lot of marine wiring that LIVES use tinned wire and gold plated terminals for about everything...

SAE and AWG are the same thing, more or less,
Both SAE and AWG were both based on the Brown & Sharp scales done before there was an SAE or AWG standard.

The biggest difference in SAE is the insulation. Automotive Insulation tends to be a little more geared to temperature than longevity, and later versions tend to melt rather than burn furiously like our older CJ wiring will do.

AWG wire comes in an 'Automotive' insulation jacket, but AWG Automotive (What you buy at most parts stores) tends to be a little better insulation if it's US Made,
If it's 'China' made, or anywhere else, the wire usually won't live up to AWG or SAE standards, and it's a crap shoot on insulation.
Since they don't have to have product liability insurance in the US, they don't really care if it lives or not.

When you wire radios or what ever, DO NOT use smaller gauge wire than is in the accessory it's self.
The longer the wire run, the larger the wire needs to be to feed the accessory. Smaller gauge wire will not deliver, and long runs build up resistance, so they won't deliver even at the same size.
This usually isn't a problem in something the size of a Jeep, but a truck or bus and you can run out of current pretty easy...

You can definitely see the effects of living near the ocean and in a region where the roads are chemically treated in the winter. There is a brine solution that roads are often pre-treated with. Add in the salt and calcium chloride (I think that is what they use) and sometimes a recent wiring "fix" won't last more than a week or two. This will be my first winter driving a CJ, but my experiences with every other vehicle tell the tale.

Do you think a jeep that was ordered from the factory to be used by the USFS would have dedicated grounds?

I'm thinking that anything ordered by the Gov't is low bid and with minimal options. So I'm duboius that they would've gone the extra mile on grounds. This bears out true when I was in the Marines, the base's staff car was a Ford Maveric with 3 on the tree, radio delete and a host of other spartanized MIA accutruments... and would've had milk crates for seats if they could've gotten away with it.

Thanks again for your insights JH! Glad to see you're still alive! Since I've last seen you on here I've gone to larger gauge wiring where ever possible and the fan upgrade and the graft of the Ford PDB, grounding bus bar, and all of the lighting wiring have come out well on 'Black Betty', I couldn't be happier with how it all turned out. Now on to the ream main seal.......

Glad to hear it's working for you guys...
Got the usual bunch still arguing I have no idea what I'm doing, (and they 'Invented' grounding, like Al Gore invented the internet), but it's all good!

Just glad to be alive, and FINALLY have some time to post again!

image.jpgThe reason I asked is because I read the military units were ordered with dedicated grounds. So I was curious if the USFS my have ordered on the same contract bid. Can anyone see the pic well enough to identify if there are any dedicated grounds?
