Not sure if problem is battery or something more?
Hello, got a 99 Vulcan 750 that had a dead battery. Selling this bike to a friend, I let him pick his new battery. It was a $38 battery off of walmart.com
I got the battery shipped to my place, threw it on the trickle charger and made sure it was full. Then I installed it on the bike and viola, the bike started like a champ.
My friend comes to pick up his new bike, 20 min of riding and he's not quite home... he stalls and the bike won't start. Battery appears to be dead.
He let's everything sit for 10 min and all of a sudden the bike "wants" to start but doesn't have enough to turn over. This seems weird to me, how did it go from completely dead to kind of dead? Overheating issue or something?
He ends up pulling the battery and bringing it to AutoZone to charge a bit, gets home, charges the battery up and goes riding to work a few days later... all good thus far, got him to work.
Now it's time to leave work and he attempts to start the bike a few times... not enough juice to start the bike.
So I'm at a loss. All due to buying the cheapest battery he could find? Charger issues?
He did the volt test... battery was around 12v when fully charged... he said it was 11 something when the bike was running. Sounds to me like the charging system is failing but even then... the battery is only good for a 10 min ride without being charged????
I saw a few sticky threads about how to test certain stuff but they are either missing the photos or the thread has changed since 2012 so we're stuck!
Any help is appreciated.
