Burgman AN 250 sccoter - battery fully charged, but no power

CHECK THE BATTERY VOLTAGE, SHOULD BE 12V OR BETTER, THE CLOCK DOESN'T NEED VERY MUCH POWER, THATS WHY IT'S THE ONLY THING WORKING.CHARGE THE BATTERY.GET A BOOST.

sounds like youre battery is faulty .take battery to be load tested

How cold? You are right if it is really cold try a bigger amp battery

My problem was: Although the Batt Light shows the "charging" the desktop indicators show the battery is at 100%. If you dscinnect the power supply the computer dies.

SOLUTION: I found this worked on both occasion it happened to me occasions.
1. Shut down the netbook.
2. Remove battery for +- 15 min.
3. Replace battery.
4. Do not switch on netbook, ie boot up, until charge light goes to green ie indicates fully charged.

This is probably due to a faulty wiring, regulator/rectifier or, less likely faulty alternator
1st check the wiring & connections from the alternator to the reg/rect (3 yellows) then check wiring to the battery (thick red)
You should get 13.5 volts (with a fully charged battery) across the battery terminals rising with the engine revs to no more than 15.5 volts, if its over then the regulator is at fault
check the alternator for continuity between the 3 yellow wires (3 pairs) at the reg/rect plug after disconnecting it. the 3 pairs should have a similar reading & none should go to earth
To check the rectifier part you need a diode drop setting on your multimeter. there should be a reading 1 way only between the red & any yellow and between the black & any yellow if not it will need renewing

Hope this helps

First get on line and go to the Suzuki scooter forum - This could be a common problem with this model

Double check the voltage on the battery. I have seen batteries with a bad cell when they are brand new.

find it, get a new one, charge it and put it in.

try replacing your rectifire becuase that is what charges the battery

the cdi unit needs replacing
