Advice, please on crimping wire connections...

[hellosailor]

I can't speak for the USN but do note that the FAA requires crimps and bans soldered splices. Oddly enough, the USAF also used crimps, I spoke to a fellow who installs miles of harnesses in combat aircraft and he said they're also prohibited from soldering, he can install a hundred pounds of wiring and it is exclusively crimped.

So that's two sources of aviation specifications, both concerned with "oops, it fell down, went boom" who say solder is no good in wiring.

And I've seen USAF test data done in the late 60's, that indicated wire wrap (or almost anything else) was more reliable than soldering, based on actual lab testing of circuit boards and other assemblies. Even with lab-quality soldering, the soldered connections to boads simply FAILED more often than anything else--including wire wraps.

ABYC standards are not meant for "yachties" they are meant for the firms that build boats, i.e. professional boat builders and professional electricians in their employ. There's never a time or place where "yachties" would be concerned with meeting ABYC specs, except by personal choice.

ABYC? Whats that? some yank thing ? Some irrelevent Standards group that has little or nothing to do with 99% of the world?

Heads up Dog. your just a sailorboy acting smart on a forum, thanks for your input but shut up till you know what your talking about,

The forum membership is international, the ABYC may be some big deal in your locality but its Nothing to me, I'm neither interested in it nor do I consider it of any signifigance.

You Americans May well crimp as a Norm. That still Does NOT make the practice Right. Nor does it put your in a position of Knowing anything of relevence beyond your Own countrys habits.

In short Dog Your a loud mouthed Yank a$$hole who'd sooner pick a fight than say something useful on an INTERNATIONAL forum.

GET YOUR HEAD ROUND THE FACT THAT YOUR YANK MENTALITY PREVENTS YOU REALISING THAT THERE IS A WHOLE WORLD OF COUNTRIES OUT THERE THAT ARE NOT INTERESTED IN YOUR CHEAP AND CHEERFULL MASSPRODUCTION METHODS and who would rather have quality and would sooner do the job right.

American standards are LOWER. You go crimp to your hearts content Dog..
and who knows... perhaps a SAIL through crimping station if market predictions showed a profit in it

You Guys go right ahead and debate it amoung yoursleves down there in Yanks ville, Meanwhile the rest of the world will continue to Solder when solder is needed

Boy, some of you guys sure take it personal when someone disagrees with you.
Bottom line it's only a freakin bilge pump. There should be at least one other electric and at least two manual pumps in addition. Crimp, solder or twist the damn things together and dip em in silicone it's gonna work. When it stops working fix it. Sheesh.

Sailing Dog: Its that kind of condescending crap that definitely makes this site entertaining. But think about it like this. You got hammered from Hong Kong and the UK. That's worldwide condemnation!

Jojo: You need to calm down. Have you ever hard of spontaneous human combustion? You might just be a candidate Dude.

By the way, I use both the crimping technique and the solder sleeves. I like the sleeves when I am running through the bilge, etc.

Jorjo, you not jumping on the "I hate America bandwagon" are you. Or have you been riding for awhile now.

[NickL]

I wonder what Capt. Bligh did, crimp or solder?

[dave.verry]

Interesting what some people get hot about. Yes, it is just a bilge pump and almost anyway will work. I have been known to cut corners in the past and do a quick repair in an inappropriate manner… and have almost always lived to regret it. I don’t know, maybe I’m just lazy, but I prefer to do a repair only once.

Jorjo is a founding member...and too dumb to realize that the ABYC is part of the ISO group that develops INTERNATIONAL standards for the marine industry.

Also, jorjo is probably too dumb to realize that bilge pumps have fairly long leads, that leave the connections well out of the bilge. There are connections that should be soldered...but the power leads to a submersible bilge pump aren't among them.

Surfesq— IMHO, I don't really see what Jorjo says as condemnation, since he doesn't have the IQ to understand what is really going on.

If you are really interested in reading about crimped electrical connections, you might want to read the article here.

I don't know of any tests between crimped and soldered connections, in a marine environment, but soldered connection have a track record of a greater rate of failure than crimped connections, and in a marine environment, you really should be using only marine-grade tinned wire, as you can see from the article I mention above.

To ALL:

Since the US (us yanks) can't do specifications correctly:

From IEC60950 (A Europian Union specification on safety of power equipment)

— wires connected by soldering are not considered to be adequately fixed unless they
are held in place near to the termination, independently of the soldered connection;
