Brown Coonnector Issues

Folks,

Ok been reading with interest the problems that the brown connectors throw up on our Tuonos, so after reading the following how 2:

I have a couple of questions, 1) why not solder the connections together and heat shrink them would that not be better? 2) does it matter which one goes to which or are they all just power feeds?

I can only think that the problem of soldering is that you dont have the benifit of easily unplugging them but why would you need to, and if you do then simply unsolder them.

My bikes seem fine and its an early 2006 so is it worth me fixing what aint broke??

Cheers
Mark

Think this link: http://www.apriliaforum.com/forums/showthread.php?91943-I-have-meltdown&highlight= and post 11 answers my question, cant for the life of me see why solder will weaken the wire its never happened to my in my line of work in the past. Boats are bound to suffer the same if not more vibration than bikes when the boat is being banged about in a force 12 in the North Sea!

My jury is still out regarding soldering those sort of joints.
The solder does not actually 'weaken' the wire...it just makes it more brittle, and prone to breaking due to vibration.

FWIW...I've just cleaned my brown connectors, and packed them with dilectric grease, and then bound them up with plenty of waterproof tape.

I agree with Tifa on this.
Also what you said about, if it ain't broke...

Which dielectric grease did you use tiffa??

It's old RS stuff that I've had in my toolbox for years...you can order it online, or just call in at Maplins, they'll have a similar product no doubt. I don't think any one make is better than another, so if it were me, I'd just get the cheapest. They all do the same job.
Make sure that the connectors fit together nice and snugly, but more importantly, check the connector wiring itself, in other words, the part of the connector where the wire is actually crimped to the connector...if it's nice and clean, then you're home and dry, but if you've got corrosion in there, I'd be inclined to cut the connectors out completely and either replace with waterproof ones, or simply take a punt and solder..

Cheers for that, think we have some stuff at work that i can use..

As a electronics engineer myself I don't buy this "fragile argument" for not hard wiring. the wires should be hard twisted then tinned with solder and heat shrink wrapped.
That will offer the less resistance to current and therefore less heat , that's what I did when my stator melted and so far so good
Connectors are only used for convenience of assembly/dis assembly it is standard electrical practise to avoid breaks in flow be it signal or voltage/current
Just my (MIET) opinion mind lol :lol
