Checked your fuses?

Yes I checked my fuse, it is fine.

I have sourced a battery charger. Am charging it now. I took the fuse out to disconnect it the circuit from the bike before charging. Funny thing is that it's gone straight to Float rather than Boast?

mmm Charged for just over 12 hours tried to start it, still nothing. The neutral light just dims. Good sign the battery is dead?

How much is a new battery and where is the best place to buy it from?

Or a bad earth on the battery to the frame.

Will have to source a multi meter I guess.

I want to play ahead, not having a bike sucks. What model battery does a GN250 take? I just had a list of models at Cycletreads and there are too many to list...

Contact Moto one in manukau. Batterys are cheap there. Just ring him.

You can get cheap batteries from repco and supercheap. Maybe around $100
Any battery supplier will have a book with car/bike models and the battery that they require.

When you do get it running, check the voltage at the battery at say 4000rpm. Once with lights on and once with lights out. It should be above 13.5V or so.
I had one years ago and the regulator/rectifier gave up, which resulted in low charging voltages, and eventually wouldn't start.

Yuasa do a cheap battery, I usually paid $60 for 'em and never had a problem.

I'd be checking:
Battery voltage without trying to start it.
Battery voltage whilst trying to start it.
Cleaning the earth.
Cleaning the positive lead.
Turn ignition off, disconnect the positive lead, turn multimeter to DC current, put the negative probe on the lead and positive on the battery positive. If there's any real current draw you have a battery drain problem.
