Default Help with wiring and electrics

I'm shit with electrics... never really got my hands dirty with it but theres a first time for everything.

I'm trying to fit auxiliary lights to my bike for the winter.

I've had a go at extending the shitty 6 inch wire that came with the lights, to around 1.5 metres of 17 amp black and red wires from Halfrauds by soldering them together (first time trying this soldering stuff...). It's not pretty but seems to be a solid joint.

The wire from the lights seems to have slightly less strands than the wire I 'm extending it with, is that a problem?

I don't have a specific Dielectric grease to waterproof the joints before heat shrinking... does anyone know if this stuff would be Dielectric?

As far as connecting it to the bike... luckily thats the easy part... just have to connect a plug to the wires and plug into can bus tool on the bike so no fuses or relays.

Cheers

if wire is thicker than the one supplied with the light i would not worry as it shouldnt cause any noticeable issue. soldering doesnt have to look pretty once its sturdy and not in a place where it will be forced to flex and possibly fracture. no idea about the grease......

The wire you are using is fine and don't worry about waterproofing the joints so long as you use long enough pieces of heatshrink it'll be fine - I'd cut the heatshrink to 2-3 cm. The most important aspect is to ensure the wires are protected from friction/fraying when you refit bodywork.

Perfect... just what I was hoping to hear.

Cheers lads.

I'm sure it won't be long until another question arises...

What's the correct/tidiest way to merge two wires into one?

Is there a specific type of connector or a specific splice? I would like to make it as waterproof as possible.

It's to merge each of the 2 fog lights live and ground cables to the other before splicing and soldering to the live and ground wires on the plug for the can bus.

Solder and heatshrink is the tidiest way, crimp-on spade connectors are good but a little fiddly to insulate neatly and they aren't ideal for high current applications. Screw-down strip connectors will give a really good connection but are a bit bulky and you'll have to wrap them with insulating tape.

The choice is yours (I'd solder and heatshrink it if it was mine) but don't burn your bike/house down.

As above. Solder and heatshrink. Any other way is wrong.

Cheers lads, I did it this way in the end. But soldered the splice before heat shrink.



Just wasn't sure as it seemed a bit bogey... worked out anyway, the lights work and I didn't burn anything down.
