I need solutions. Check engine light and battery light on when driving...and she won't turn over when hot. So where do I get a battery?

 

FYI '12 RoadKing Classic...

 

some say walmart, i myself went to battery plus.... others will also have ideas for you to

 

Just got one of these earlier this week. Perfect fit, and plenty of battery to do the job.

I just replaced mine with another Interstate Battery from the local store. Six years without any problems but it was time.

 

you might want to figure out why the warning lights are on - the regulators on some 2012's were recalled, and some (like mine) failed but were outside the recall dates.

 

Don't spend a penny on a battery till you verify the charging system is working properly. This sounds like it could be a regulator or stator issue, just as easy as a bad battery.

 

Ok. Sorry first time on this issue. Any way to do that without having to take it to the shop? Thx for any input..

 

In other words can I use a obd2 on it?

 

I have a '13 flhtk and the same issue just 2 days ago. Got to get the bike to my wrench to check the codes. Some say it could be the stator others say the voltage regulator and some say both. Either way i wouldnt just change a battery, get it diagnosed
