charging system nfg ; battery takes charge but dies after riding

[Randy Grein]

No, you are correct to suspect the charging system. Start by checking charging voltage; should be between 13.6 and 14.25v. it is it's time to clean the battery posts (rare). If not use the checklist in the manual; stator resistance, etc. Not uncommon for excessive charging from a dying battery to take out the charging system.

After doing some careful testing it's clear what's happening -- I can put it on a battery tender and get 4-5 (errand/trip) rides from it, but the battery is dead after that.  But it does accept a charge and does run quite well.
