I have an old ironhead rode yesterday ran great. Left on it to drive to work and it ran fine till my last few miles. At that point I noticed the headlights Was dim then bike just shut down. Coasted to stop checked wires see if anything was loose. Everything looked good. Turned key on kicked it. She fired up and ran great for 1/2 mile then fell dead. Again Coasted to stop. Waited a couple minutes turned on she fired back up I let it idle after three minutes or so lights went dim she died. Any ideas? Gen reg bat???

 

Battery is probably shot, and charging system not functioning. Enough battery power to keep igntion going for a while, then it dies. You shut it off and let the battery rest and it recoverers enough to get it fired up again and then not enough juice to keep ignition system power it dies and so on and so on.

I'd check and probably **** can the battery and start from there checking out the charging system.

 

Looks like your right blackcherry battery had dead cell. Thanks for the help.

 

No prob, let us know if you need anything else, lots of good IH guys here.
