I have a 1975 cb125s, build that I am just wrapping up, and have run into an issue.
When I purchased the bike, the previous owner had made a comment along the lines of "these bikes don't have charging systems." An I thought that was really weird. So I assumed the charging system was maybe just not working correctly. Upon year down I found numerous bad connections and whatnot so I figured that was probably the issue. Buttoned everything up, and have ridden the bike numerous times during the day and it runs perfect. The last few nights I have taken small trips and the last night I had it out I started to develop a slight stumble at lower rpms. It got worse until it would die upon deceleration.
Long story short, I have a dead battery. Runs great with no headlight on. Dies or stumbles with it on.
It's the stock 6v system. The only thing I have changed is a new battery (sealed lead acid) so it could be tipped on it's sides and tucked away, but the specs should be close to stock.
How do these charging systems work? Do they only charge with the light on? How do I test if it's charging? How do I know which component to replace of it isn't charging?
I've heard a little bit about a 12v swap, and this might be a good time to do it I I need to replace components anyways. What would I need for that? Any insight into how this thing is "suppose" to function would be great! Thanks
