Wire splicing - to solder or heat shrink connectors ?

bang4dabuck · Apr 15, 2012

A couple are crappy at the terminal bar. They are from the harness side. They purple one and the red/purple wires were dry rotted and are full of corrosion. I figure if I cut them back far enough, I'll lose a lot of the corrosion.

What model motor are we talking about here?.....i had the same problem on my 60hp and decided to replace the motor harness from the plug with new and be done with it.....the motor was worth the coin. If an area has already started to dry rot the rest wont be far behind, but do what you think is right for your situation.....

I use non insulated tubular connectors and crimp with a proper crimper that leaves a strong indent in the center of the crimp . The heat shrink goes over that.

Or these. Kills 2 birds with one stone.

Theyre too expensive and the insulation is too hard and inflexible. Standard heat shrink tubing works much better.

These are the crimpers to use no matter what type of crimp connector you may use.

These are the non insulated butt crimp connectors. Insulation over the top makes for a poor splice and the insulation will break through if the indented crimp jaws are used. Insulation over the crimp is preferred.

I love butt connectors and I also can't solder worth a damn so I always crimp. As far as the heat shrink connectors I use them sometimes. I just rewired the whole interior of my boat and I used them to protect from moisture. If its something thats likely to get actually wet than I use regular ones and shrink tube.

solder, wipe any excess paste residue off with solvent, dab some silicon on the joint, slide heat shrink over it, and you have a corrosion/moisture free fix.

I do not like solder anywhere on a boat/motor. It actually becomes more brittle and less flexible from the solder connection. I vote for the crimped connections with heat shrink overtop.

Like i said.....if you can afford it, its available and your motor is worth it.....buy the harness and be done with it.

I just spent most of the day re-wiring, splicing and heat shrinking over top, so I guess that's my final answer!

Harness is CDI $125 to my door. It seems like overkill to replace whole thing. Not sure why those 2 wires are so nasty. Looks like a lot of good ideas here so I will sort through.

That's about what i paid for mine.....it was justified in my case because the old one was pretty far gone and not worth messing around with.....i hope you repair yours successfully.

This place has the heat shrink crimp connectors for a reasonable price...about .30 to .40 each.
That is half of what the post above prices out at.
I do not recommend the ones that have a solder bead in them...they are too hard to crimp right.

Lots of styles, types, sizes. Quick shipping.
