Been having trouble with my 09 nightster having issues with holding a charge after riding a while the engine light and battery light come on, I just replaced the battery and still doing the same thing, this is the third battery in the last year I replace, the bike has an aftermarket passing lamps and nothing else that I could think that would be draining the battery any help would be great. Thanks

 

Make sure you don't have an electrical short from changing the passing lamps.

 

I'm thinking about removing them all together

 

you said engine light and battery light come on?

you got the harley blues son..............bad stator

 

Your battery probably isn't draining, your charging system (regulator or stator) probably isn't charging.

 

Had a bad stator on my 08 at around 32K miles. Seems like this is a common problem and not really designed or QCed to last that long.

I was dumb enough to buy the extended service plan so it only cost me the $50 deductible I'm still praying more **** goes wrong on my bike so I can get all my money's worth on that ESP.

 

Thanks ratrod bad stator huh what the hell else could go wrong it's sad when the tech at the Harley shop tells u that they under engineered the bike and that the electrical system stayed the same it and can't handle all the electronic stuff that comes with the EFI system

 

Yeah both lights come on after riding a while once the bike just died no battery whatsoever pissed me off I was 70 miles from home

 

mt battery was 8 years old and working fine untill the stator went.

 

I guess I will be changing the stator seems everyone thinks that is the issue hopefully that will fix it onceandfor all. Thanks again
