Re: How not to wire a boat!

No matter how you make your connection you have to properly seal it. What happens when you put copper, tin and lead, three different metals in contact in a wet environment (an electrolyte), all carrying current? - electrolysis

And on and on we go. You say tomato and I say tomatoe.<br /><br />Do away with all electrical systems and buy a set of oars I say!!!!!

Re: How not to wire a boat!

To repeat what Ralph said, "No matter how you make your connection you have to properly seal it." This is why if I crimp and I can't use heatshrink tubing or liquid elec tape, I always use di-electric grease. It's amazing how much protection is provided by so little grease. Just a light coating seals out moisture and corrosion. Works great on the wiring connector between the trailer and the tow-vehicle.

Re: How not to wire a boat!

I know that does not look the best , many ways to do wiring, just be thankful that the guy that wired in a radio to my boat was not in yours! GREEN had 12 volts positive !!

Re: How not to wire a boat!

I did succeed in 90% of the wireing but I had to resort to Soldering. :( <br /><br />I was trying to bend the + and - wway to many times and the crimp on the 6 guage stuff bent and came out. I was just about ready to slide the heat shrink on it too. Instead of removeing the wires and using more lugs and the hammer thing I just got out the torch and the solder. Stripped the 1.5 requred and soldered the darn thing. Also heat shrank it. <br /><br />Good thing that was the first two crimps I did they held well but I was moving the wires at a pretty good angle to the lug and messed it all up.<br /><br />All the other wires are 14-16 guage and crimped then shrunk on.

Re: How not to wire a boat!

Which raises the original question. Crimping or soldering? <br /><br />Would the connection also have failed if you had soldered it first instead of crimping then subjected it to a similiar degree of movement?

Re: How not to wire a boat!

The bigger wires with lugs are harder to crimp properly. I saw that crimper you used (I think you posted a pic somewhere) and was going to ask how it worked. It was this one right?<br />

<br /><br />If you do a lot you want something like this:<br />

<br /><br />I have had really good luck with this one, which has dies for the different sizes:<br />

<br /><br />You may want to check the other ones you did with that tool and yes you would be better off soldering and crimping in this case as the tools is not making a good crimp.

Re: How not to wire a boat!

Basically I had not cut the insulation back far engough and the crimp was hit 1 time. Thats what I was told so when the failed I had it under the dasboard. I was not going to undo all the wires and then try to crimp in the boat. Solder was easier under the dash to do. The other wires I did out of the boat and hammered the crap out of the lugs. :) They did not come loose and I was bending them to but not as sever as under the dash and had a bit more wire exposed. I then heat shrank them with thicker sleeved stuff.

No mine was designed for welding wires and looks close to that one. Its black and the saddle area is not as smooth. <br /><br />It did work much muc better when I hit the lug along the barrel and not just 1 time. Had a tug of war with the kid and the 7" yellow conductor to see if it would pull out and it held well! The other 7" red conductor was used for the Circuitbreaker in the boat. Not subject to this test however. :D

Re: How not to wire a boat!

That may explain it. Even with the one I use it takes several hits to complete the crimp but it is a die so there is no risk of deforming.

Re: How not to wire a boat!

That blue crimper is nice. Usually smaller than 4in to fit in a vice so you don’t have to smack it, but you can smack it if you just need to. They can be had for about $15-$18, plus $800.00 shipping.<br /> :) <br /><br />I don’t think the crimp vs. solder topic has been thoroughly covered yet, so I’ll mention that electrical copper is of a softer variety. When you crimp (or smash the crap out of) a connector to a copper wire, the copper in the wire (and tin, if coated) deforms and molds to the surface imperfections and pores of the connector, making a virtual weld. The individual strands of the wire do the same thing with respect to each other. They deform and compress against each other to make a superior electrical connection. Overall, the mechanics of a crimped connection is very secure.<br /><br />David, are you awake, yet???<br /> :D

I've certainly enjoyed following this discussion!<br /><br />What bugged me about the OP was that the point of the original post appeared to be pointing out how the prior owner had done sloppy work and "here's the correct way" to do it. When questioned, the response was- I don't really care, this is how I'm doing it. Pot<->Kettle<br /><br />Now I see a post that talks about "smashing the crap" out of the connector and follows up with "overall, crimps are very secure connections". PROPERLY crimped connections are very mechanically sound. I think the OP found out the hard way about properly crimped connections...<br /><br />Someone mentioned the relative skill levels associated with either crimping or soldering. I would argue that they BOTH require skill AND the proper tools to do correctly.<br /><br />It seems the old adage holds true- when you equip some people with a hammer, everything looks like a nail.

Re: How not to wire a boat!

Rastro I tried to be gentle but got burned so to speak, so I used the hammer correctly. :D <br /><br />I was told 1 hit to crimp the wires it worked however it takes two and a small move to get the correct crimp. The little crimper did not have instructions either.

Re: How not to wire a boat!

My final opinion on this post is this. Realgun, for what it is worth you have gained alot of my respect. You hold to your belief that crimping is better than soldering. We have have many heated discussions as a community. And you still had the integrity to admit that you soldered a connection. Unless you keep your boat for eons you probably will never have a problem with any (most) of your connections. But my respect comes from admitting that you soldered a connection. You did not admit it was better. You did not denounce it. You in essence gave credit to soldering as an acceptable method. You also opened yourself up to criticism and ridicule from the "I told you so" crowd. My hat is off to you. Thank you.

I wasn't picking on your situation. I suspect many have been in the same position- I know I have. I have all the correct crimpers at work. I personally only own a few and they are for the more common terminations that I do on a regular basis. So I have the exposure to the correct tools but often do not have access to them for my personal use. This is where is gets tough- you know the correct way but do not have the correct tool. So you're forced to make the best of the situation. For me, that's the best mechanical crimp I can make followed by soldering.<br /><br />What got me going was my perception of the initial tone of the discussion and then the follow ups on right versus wrong- especially when a bad practice is highlighted by someone who is acting as an authority on the "correct" method.<br /><br />As the prior post points out, you will most likely never have a problem with the work you have done. We all have our own circumstances to weigh when determining what is sufficient to reduce the risk to acceptable levels. Most of my boating is on fresh water lakes of small to medium size. I can afford more risk than someone who is going out to sea with their boat. I think we're often clouded by our own circumstances and risk tolerance on topics like this.

I think you're dead on Rastro. I boat in the ocean, often far from shore. A good day is 2' - 3' chop which can turn to 8' seas in minutes. I have on many occasions had my 6,600+ lb Formula completely air born only to slam into a trough or the crest of the next wave. In this kind of an environment you quickly become risk averse :) <br /><br />I'm also biased by the fact that I assume people who ask for help are DIYers w/o much boat wiring or soldering experience and they are wiring something more than just optional, non-essential accessories. So, it is often better to recommend people crimp otherwise you risk people thinking the soldering technique recommended here in another thread is acceptable and just when they need their boat the most (like in heavy seas) it quits on them and puts them at risk.<br /><br />Now, what are you doing up on the North Shore boating in fresh water! :)

Here's one reason:<br /><br />

:D <br /><br />I go fishing alot after work hours and that doesn't leave much time so I often go where I can launch and get to the fishing spots ASAP. My fiancee is more of a fanatic than I am and lately she's been pressing for some striper action. We spend perhaps 50% of our fishing time in a canoe catching 5lb largemouth on some of the smaller ponds, 40% of the time in the bass boat and the remaining 10% of the time in salt water.

Re: How not to wire a boat!

When I started this thread i was under the impression that to join wires you need either a 3 way connector or a bus of some sort. All wire were to be crimped per ABYC and soldered if you felt inclined. I did not. :) However the ABYC also said large battery wire could be soldered per the 1.5 diameter rule. <br /><br />What I saw in the boat shocked me as all the negatives were wrapped into the main wire which was a 12 guage not 8 like it really needed. (I used 6 for my own reasons). And the wires were then soldered and actually looked OK to me they was wrapped in electical tape. I unwound about 40 feet of tape!<br /><br /> The other issue I had was when I got the boat home I tested all the accessories and they worked.<br />I then hooked up the batteery a year later, I had not touched any wireing, and nothing woreked and no fuses were blown. There were fuses thrown into the splashell however that were blown. I never found where those fuses came from.<br /><br />Now the ony wire thats in the boat is the engine and tilt wires all others have been replaced. I will attack the basttery cables later. Every wire is the proper colr except the horn which is red which should be orange but was to lazy and broke to but some. :D Only needed 6 feet BTW.<br /><br />DavidL I never said soldering was bad only that it could not be the only method except as noted about battery cable and lugs.<br /><br />Thank you all for posting/helping me!!!!!

Re: How not to wire a boat!

Realgun.....if you want to use a good tape for wraping, use Scotch 33. It really resist gas, gas fumes and oils. Regular electrical tape will lose it's hold after a while in a marine invironment. Dang I hate it when I have to unwrap a bundle that's been wrapped in regular tape....black goo all over the place....
