Electrical problems

[b1ade]

Just when i had finally thought i had finished the nc30, i took her out for a run, parked up went to start her again and the battery died. Thought i had sorted this problem by fitting a new regulator.
The battery is fine onced charged (according to the opti-mate), and if i ride without my lights on the battery does charge, but dies with the lights on. I have checked all connections, fuses and wiring and it all seems to be fine, but without a multi meter cant be 100% sure all part r working.
Can anyone think of what might be causing the battery to die?

My Son has an NC30 and we went through all sorts of problems with the charging circuit!

There is a plug and socket affair, as I remember it it is on the right hand side of the bike, the connector and wires there cause problems and burn. If you have burnt wires and connector you have a big problem, we bypassed the loom, with new heavy duty wires run straight from the reg/rect unit to the stator coils. and soldered the connections.

Open up the generator cover and take a look at the stator coils, if they look at all burnt or smell burnt then they are probably knackered.

The only real way to find out what is going on is with a meter. A cheap meter can be had from about £5 you need to see a significant voltage increase when the engine is started and running at 3k

The other thing that can be checked if you have a meter is the coils resistance, there are 3 wires and the resistance between any two of the three should be the same.

I did have some burnt out wires on the reg/rect melted all the plastics too, the previous owner put the wrong reg/rec on it, but i replaced it and cut the wires back and thought that would solve the problem.
Looks like i will have to get a meter after all, thanks for the advise.
