Hi all hopefully someone has an answer to my non charging problems with my kg twin, it has been in storage for 7 years and when started did not charge the battery(when previously it did!),i have put new brushes and cleaned the commutator ,the output was 0.9 v! i flashed it on a 12v battery (neg earth) and it gives a healthy 9v now,you can motor it but it does not rotate very fast. still no charge at the amp meter ,changed the control box with another bike that was working ok ,the cut out was pulling in ok on tickover so i assumed that it was working at last. i went for a 10 mile ride with the lights on and it flattened the battery completely! the battery is new but only 4 ah . does anybody have any ideas.
apologies if it has been covered on previous posts philip
