Hi everyone I'm Shane..i live in mandurah western Australia. I don't have a motorbike as such but a buggy with an xs400 motor. I don't use it alot, maybe a few hours a month. My question is..Is the magneto/alternators sole purpose to charge up the battery? Does it have any other purpose? I wanted to run a battery bank instead to keep 12v..that grommet where the magneto wires go through at the bottom of cover is always leaking and I want it gone if possible.. Only electrics I I I have are led bar lights and starter motor. Cheers for any help provided..great site.. Thanks
