2009 Dyna Low Rider battery fried
The battery on my 09 Low Rider was recently replaced and ran fine for awhile, then all of a sudden started cutting out. Upon inspection, I found that the little wires coming off both the + and - posts of the battery were fried. I was told it was from arcing from incorrect installation of the battery. I really doubt that the cables weren't tightened correctly, but anyway, how can I remedy this situation without having a huge expense from the dealer? Exactly what are those smaller cables coming off the battery terminals? Can I run replacement wires without having a too involved "fix it" job? Any help would be greatly appreciated!
Thanks, guys!

I had the same problem on my 08. Like you mentioned from other searches, mine was from loose cables. Even though I cranked thrm down with a screwdriver, I should have put a socket on them and went a little more..

You can repair it yourself, it should of blown a fuse if they hooked the battery wrong.
I replaced my cables when I installed a more powerful starter 1.4/1.7Kw and I used heavier braided welding cables and silver soldered 5/16" ends to the battery. I didn't like the small screws that come with the batteries and drilled and tapped for 5/16-18 bolts and it worked great. So I use the brass 5/16" hex head bolts and star washers and keep a secure connection. Easy to do and keeps the connections tight.

I'm not Mkos1980 but the terminals need to be clean and tight. You should use a stainless wire brush to clean both the battery terminal and the cable. A little grease on assembly will help stop corrosion from reoccuring.. Make sure that the cables are oriented so that the cable won't twist the battery bolt loose when coupled with vibration from the motor. Check the terminals regularly for tightness. HDs seem to want to vibrate the terminals loose.. I killed batteries by missing that the terminals were loose.

How did you silver solder the 5/16 ends too then battery.. I thought the battery terminals were lead coated.
I had trouble with the standard little screws loosening all the time, tapped with 5/16-18 into the post and here is a much more secure connection.

Takes more heat than regular solder but last.

to work for wires. For me it requires too much heat. Was wondering if what you had worked better at lower temps and if so what brand it was.
FWIW In the case of a soldered lug, the old lead stuff was plenty strong.
