Problems with dyno charging
« on: 26.12. 2022 18:22 »
I have 1959 bsa a10 and having some problems with charging. I’ve noticed that the amp meter when I’m riding the bike is not moving and that means it’s not charging. I have the battery flat dead but I believe that has nothing to do with the charging system, I opened the timing side cover to check the belt and belt looks to be working fine as well.

So what’s my next move? What should I check next please? Thanks for any help

Hi Marvic,
Some electronic regulators will not work when the battery is flat
Start off with a known good battery and see what works first
