Any light wiring experts around?
I've got a C&B seen battery that died mid ride - cable was pretty loose on the connector jack so took the connector apart - wires had pulled away from the solder (well, I've obviously been heavy handed and pulled it away!). It's 3 core, red, black and yellow. Two solder points on the connector. Any ideas which colour wire goes to inner or outer part of connector? I've tried dabbing the wires on the solder points in various combos but nothing doing!
No expert on bike lights but 'usually' red would be positive and that will 'usually' be the centre pin. Black would then be negative and the outer pin.
Have you got a multimeter to check the polarity of the wires. Don't know about the yellow. Remote switch? Is the cable screened (no real reason it would be).
No multimeter. I'll try soldering red centre and black outer tonight and see what happens!
I can only see 2 soldering marks so not sure whether the yellow was even connected..
The charger should have a label that should confirm that the center pin is positive.
If there has been a short circuit it might have tripped the protection board on the battery
sometimes this self-resets but I have had some that require to be put back on the charger to reset - (the point being that there will be no voltage on the battery output if the circuit has correctly protected the battery.
Good steer thanks for that I'll check the charger..
Forget all that claptrap, only thing to do with batteries that aren't working is piss on them or chuck 'em in the freezer! Proper blokes don't use lights anyway!
Great I'll look forward to a demo of proper bloke night riding on weds then!
Careful with this. Lion batteries can start house fires easily with wiring defects. Not necessarily while on charge, anytime is good. Soldering directly on the battery terminals can cause them to explode like frag grenades too.
Honestly, I’d take this to someone who knows about lion batteries rather than diy and never be sure it wasn’t a big problem waiting to happen.
