trying to help a friend out here but he took his bike out for a ride a few days ago and it died on him so he replaced the battery after getting it tested but again it died today. the previous owner said he replaced the alternator and belt? i didnt think it had a belt but i havent looked at the bike yet or delt with an older one. Im heading over there tommorow to check i out. how should i check if the alternator is bad or if its just bad wiring. any ideas from my vague description? lol
