I bought a used 2007 XL 1200 Custom a couple weeks ago that has quite a few miles (21500, actually), but has been very well maintained (oil changes every 2500).&nbsp\\; The check engine and battery lights came on yesterday on my way home from work.&nbsp\\; I found a post about the Diagnostic Trouble Codes, and how to find out what the problem on your bike is.&nbsp\\; I got the Battery Voltage Low code.&nbsp\\; What risk am I running if I still ride it?&nbsp\\; It starts and runs fine.&nbsp\\; Can I charge the battery, or does replacing it sound like a necessity?&nbsp\\; It's my first motorcycle, and I just want to be out on the road!!!!!

First thing to do is check your battery terminals and make sure they are tight.

Check the ground where it connects to the engine,next to the starter.I had the same problem,just a loose connection.

check all your connections like posted above, then charge your battery with a motorcycle battery charger/tender with float mode. Its 20 bucks at walmart. then see if it throws the code again. If it does, buy a new Battery.

Don't forget when you check the terminals to make sure they're all on tight, that you check out the terminals and look for corrosion.&nbsp\\; If there is any, get one of those sponges that have the sandpaper all around them and scrub the terminals down shiny.&nbsp\\; Good luck!

i had the same problem last month, it first affect the electric starter, you'll notice that it doesn't start right away.&nbsp\\; then the ignition system will be affected too.&nbsp\\; finally the engine won't start at all.

Unless you have proper equipment and understand about bike electrical system, better take it to workshop and let a mechanic take a look at the problem.&nbsp\\;

Connections first. if that don't do it make sure u are charging Then battery.U don't need to be broke down with electronics!!!!!!!

Thanks for the input y'all.&nbsp\\;Checked all the connections, everything's tight.&nbsp\\; In fact, the ground negative connection was so tightly screwed to the ground point that the nut fuzed to the ground wire and I can't get it loose to take the battery out and charge it.&nbsp\\; I wanted to take it out and attach the ring connectors to use conveniently when needed, but the ground wire just twists when I try to loosen the nut.&nbsp\\; I can't get enough range of motion to break it loose.&nbsp\\; Can I connect the charger clamps to the end of the ground wire (I wouldn't think so, but I'm no mechanic) and then to the positive terminal, or am I stuck taking it to a pro?&nbsp\\;

Is there something draining the battery? Any add ons that may be draining it?

Re-tighten the connections.&nbsp\\;\\\\\\; If you have a volt meter, measure the battery voltage with the bike off (12.5 volts), then with the bike running(13.5 to 14).&nbsp\\;\\\\\\;&nbsp\\;\\\\\\;If you don't get a marked increase in voltage while running, you have a charging problem. You definitely DO NOT want to ride until you get this resolved or you WILL be stranded sooner or later.
