About a week or so ago I went out to the garage, removed the tender plug from my 06 road king, hopped on and took off. A mile or so down the road I look down and the engine light and battery light were on. Pulled over, shut her down and checked the codes. It flashed P0562, that's it. Started right back up and continued on thinking well I have insurance with a tow so screw it. A couple more miles the engine and battery lights turned off. Got to my destination about 20 miles away shut it off and walked away. The next time I started her the lights came in again about a mile down the road but shut off shortly after during the same trip. They haven't come back on since.

Can a battery tender fail causing a low battery hence low voltage? And by riding it charged it back up? Has anyone experienced a error code that showed up once and went away without any further issues?

Not sure where to start. I am ok with tools and doing minor to moderate repairs but I'm no electrician.

 

I would think it could, yes. Or even if its a good tender, battery could in fact be bad.

 

I don't know what the stock battery was but this is an old police bike and I'm fairly certain they replaced the battery but how long ago I have no clue. So I should probably get a new one regardless.

 

I had a similar problem with my '08 FLHT, and it turned out the voltage regulator was going bad. Try resetting the code to see if it comes back. After replacing the regulator, the fault has not returned, and all is well.

 

Ok I'll look up how to clear the code and see what happens

 

The code came on my road king last year. Took to the shop got new regulator and battery.Now its back on again,but dont stay on. What could it be now? Maybe something loose?

 

The code could be a history code and until the dealer clears it, it could keep coming back. Now if you don't know how to do the check of battery and regulator along with stator it would be a good idea to bring it to the dealer for them to diagnose.

 

With an 06 it very well could be any of the 3 major Electrical components mentioned above in the last post I would start there for sure. Electrical components mentioned above in the last post I would start there for sure

 

Could be the same thing. Or could be something different.
You have three choices.
1, get an FSM and learn to do your own work.
2, take it back to the shop
3, do nothing at all

There's too much information just a Google search away for you to expect any meaningful answers from such a vague question on a complicated subject.

 

If the code is recurring after clearing, I would definitely get it checked if your not comfortable doing it yourself.

Simple and free check would be to pull the battery after a ride and take it to an auto parts store or Batteries Plus and have it load tested. If that's good, buy a ten dollar meter and check voltage at the battery with the bike running. It should be at or over 13.5 volts.

After that, you can use that same meter and follow the electrical troubleshooting steps you can find here on the forum by searching to determine stator or regulator . It could be anything but in my experience on my bikes, low voltage is usually the stator. High voltage is the regulator. And one going bad can take out the other so you may need both.

Regulator is very easy to do yourself. Stator not so much.

Good luck!!
