I posted this on the Sportster section too.

I have a 2003 883r. I had to replace the original battery about a month ago. Now the new battery is also dead.

This is what happend:

The original battery seemed to just wind down. I charged it once and it worked. But when I was out riding I stopped for fuel and it was dead. I got a jump and made it home where it was dead again. So I bought a new battery at Wal-mart. I had to put the acid in it, charge it and install it. The new battery worked great for 4 weeks. Today I went out to start it and click-click-click. I put a meter on it and it's reading 10 volts. I have it on the charger again, but I was wondering if maybe the bike isn't keeping the battery charged. Regulator maybe? or the starter going bad? Any help would be great. Thanks

 

UPDATE

I charged the battery today. The bike started right up. I rode around town, highway and sidestreets. I was oiut for about an hour. Got it home,turned it off, tried to restart it and click-click-click. The battery won't hold the charge. Could it be the stator?

 

It would be interesting to know what kind of voltage is going into the battery at rpm's above idle.

 

Sounds like Stator/or Regultor, My Fatboy would go dead on Hwy at 70mph, replaced
Voltage Regulator, still went dead, replaced STATOR, BEEN 4 YEARS NOW, no DEAD battery
