How to Make a Waterproof Splice (Wire)

[Used_Cars]

I'm working on my Seadoo. There's a beeper (technically called a "buzzer", but it beeps) powered off 12 VDC battery. It's a "logic" thing, one beep means no key, two beeps means ready to start, etc... about 1 1/4" cylinder, has two wires (positive and negative) going to it. There's several repair options, but the easiest is to simply cut the wire, splice in a new beeper. If it weren't wet, I'd use small electrical screw caps and electrical tape, or those tube-style connectors you crush with two wires in it, but this is a Seadoo and it will get wet, so I want to know how to splice two 12-volt wires together so that water can't penetrate the repair.

Ideally, in my mind I imagine covering the spliced wires with heat shrink, and using a syringe to inject some kind of liquid rubber into the tube. Then heat the heat shrink up and everything hardens. I doubt that kind of thing exists, but that's what I imagine would be best.

you can buy heatshrink sleeve with a lining of hot-glue.

solder the wires together and put the sleeving over the joint, heat it with a hair dryer and the sleeve will shrink around the joint and the glue will melt and seal it.

Got it. I read the directions and gathered that what was missing from my awareness was the idea that they make heat shrink with glue already in it. There's a few names I see. I'll probably be buying from eBay. Any recommendations? I don't have a diameter/gauge of wire, but it's standard for 12 volt stuff. 12 gauge? 14?

For buzzer only? The wire is probably real small, 12AWG wire is made for 20A circuit.

It's a small wire with heavy insulation, but truthfully I have no idea what gauge. Tomorrow I'll put a gauge measuring thing on it to be certain. But this stuff shrinks down to 1 1/2 /16ths of an inch:

Is this good?

I'm going to solder the wires together for connectivity, then use a crush splice thing for strength then put this heat shrink on it for water proofing. I'll post a pic tomorrow if anyone thinks that will be useful.

This is waterproof. The barrel part crimps on both wires then you slide the sleeve over the barrel and shrink it down. The sleeve is stiff plastic with soft plastic rings on each end. The soft plastic melts and fills the end of the sleeve sealing it. Comes in three sizes. Red, blue, and yellow for various sizes of wire. Red for 24, 22, or 20 gauge blue for 20, 18, 16 and yellow for the big stuff. http://www.te.com/usa-en/product-650082-000.html .

There should be marking on the wire that shows the wire gauge and Voltage rating.
