I'm trying to help my son fix his moped from his telephoned information that "The battery runs down in a few hours". Basically I know nothing about moped circuitry and there seems precious little help on the web about this. I can't even locate a workshop/service manual for the machine (A '92 Yamamha Slider). Anyone have a circuit diagram/description/any information about this kind of moped? I don't even know what the battery voltage is - I guess 6V lead acid(?). I'm planning a visit next week so would very much like to take kit to try and help him. I can measure the current drain in case something is taking current with the igition off - but I think it may be the charging circuit that's at fault. Is this similar to a car - alternator, rgulator module, battery? Your help much appreciated.
-Thanks
