The Nerminater

I have a 1984 French import XT250 6v with a battery thats almost always flat, no indicators and a real poor headlight, virtually non existant out in the unlit countryside roads. I just read your thread Neo and am wondering why there is no mention of swapping the yellow and white wires over so that the battery is charged off the lighting circuit and the headlamp runs off the charging circuit if that kicks out more voltage sooner in the rev range? Wont that mean that the light goes brighter sooner rather than after 3000 rpm?. Also speedshop, can you rewind my lighting coil? what else would I have to change and at what total cost? and what maximum size of headlight bulb might I realistically be able to run? Thanks if you read this as time seems to have passed slightly since you all wrote this!!!
