Came home from work yesterday morning and left my switch on overnight. This morning battery was dead as a doornail, i jumped it off from a extra battery and it started right up, but as soon as you remove the jumper cables it died. I than removed the battery and put the extra battery in, it has been sitting a few months but it did start the bike although it turned over slowly. The bike ran fine about 15min. and then it died and now this battery will not start the bike. the lights are also dim. Could leaving the ing. switch on overnight have damaged the stator, or voltage regulator ? any ideas are appreciated. Thanks ps: The bike is an 2003 Road King with 22,000 mi.


I charged the battery for 24 hrs as most of you suggested and it worked ....many thanks for all the great advice.

 

No chance of damage to stator or regulator - of that I am as certain as can be, but...I can't understand why the bike should cut out once it has started, especially in the second case.

I would give the original battery a healthy slow recharge and see if the bike sorts itself out

 

No way you damaged the Stator or Rectifier/Regulator. Good advise above. Battery just needs a good, long, slow, and I repeat SLOW charge. Once done, you'll be fine. Oh, and get yourself a battery tender, hard wire the pig tails into your battery so you can just plug it in and out very easily. Your battery will go 3-5 years at least. I've gotten as much as 6 years out of mine with religious use of the Battery Tender.

 

I have no luck charging batteries that have been run down to 0 tried trickle charge

but it still would not hold a charge per my meter on my large charger so i bought

a new one and solved the problem good luck-ride safe

 

If the battery is good, and this is the first time it's happened, it should take the charge fine.

 

Thanks for the replies guys, i have the battery charging.

 

Yep, be patient and don't even think about hitting that starter button until it has charged at the minimum 24 hrs or more. My neighbor did the same thing and I think it took a good day and a half to get it charged up. Been running good on the same batt for over a year now.

 

Left mine on overnight a while back too. Same thing dead as a doornail. Charged overnight and all is good. Been using a tender ever since.

 

Thanks again guy's
