electrics help (simple)

[cqueen]

I know this should be in workshop but I dont have time to wait for an answer and its a pretty simple question.

The cable which connects to the battery on my bike has melted on the exhaust, Ive snipped it off & Im wondering if it will be safe to solder on a new piece of house wire like so...? what with high currents & so.

I woudlnt myself.. unless you know the rateing (something like 60/70amps?

Get down halfrauds or a car shop and get some propper battery cable and terminals

Quite simply isn't worth the risk of seting yourself or your bike on fire

well the other end goes into some black box and I don't really wanna be rooting around in that.

[mr.z]

Probably the starter relay..

The wire will be roughly
8mm 105amp
9.2mm 170amp
11.3mm 300amp
depending on the wire thickness..

If you so solder them back together you should use heatshrink to cover the join, and some kind of anti abrasive shelding.. anything less and it will come back to haunt you

Including insulation its 4mm thick, the wire itself is only 2mm thick, its just a 110cc.

EDIT: oh and on the wiring diagram it says the battery is: 12v - 4Ah if that means anything to you?

[mr.z]

Has it got an electric start at all? if not it could be the regulator/rectifier maybe? have you got the wiring diagram on your pc?

I'd still use propper similar sized cable + shielding though, the house cable might take it, but it might not..

Does the wire just dissapear inside this black box or has it got a terminal of some sort?

take the lil bit to halfords and get some more wire, then solder it back together or use chock block,
it will be fine

Someone stupid does not realise they r stupid.stupidity is indistinguishable from malice U just have to accept that some people are thick as p1gsh1t and work around them.

[cqueen]

Yeah I only need it for the electric start, otherwise the battery isnt needed at all.

I have got the wiring diagram...

My dad recons I should get a crimping set.

[cqueen]

Hey, wouldn't it be cool if someone created an animated wiring diagram, so you can see where it all goes and what it does?!

[daz|n00by]

Get a crimmping set with higher voltage fittings in m8,
and if your worried about the weather getting at it get some shrink cover,the stuff that shrinks when you apply heat to it .

Housing wire is not flexible or weatherproof enough, you need some proper vehicle wire of the same thickness.

I would solder the two together and shrink-tube over the top. A crimp would be equally effective.

Probably best to make up a whole new bit of wire with a ring terminal on the end and splice it on to what is left, the fewer joints you have, the better.

Or bodge it like i would. Fit any wire you can find, just twist them together and cover it in shit loads of black insulation tape.

Not had a problem yet.

Surely someone who does PAT testing should know a little bit about electricity and wiring? Like about electrical fires being bad, that kind of thing.

Oh FFS

If you want to fuck up your own electrics then fine, if your bike ends up looking this this its your own stupid twat fault

If you dont have any information based on real knowlege then stfu


This isn't aimed at anyone in particular, but there some pretty dumb ass advice give out sometimes and its a fucking dangeorus as handing out sparklers to kids at a petol station

Yeh but thats clearly a one off, just because you join a dodgy wire with just insulating tape doesn't mean the bikes gonna catch fire.
