I've had my 2007/ 400 for about five years. Been riding other stuff for 30+ years. This was my favorite bike, very dependable, until I replaced the battery. I have since re-replaced the battery twice and my electrical problem is still around. Just not enough juice to turn over. My mechanic troubleshot, replaced the starter relay. He tells me that the charging system is good, no codes, no draw on the battery. Still, my Burg starts up initially but only if right off the tender, then I end up getting stranded when I stop because she won't start without a jump. I don't want to push it home anymore. What should I look at next to try and get the gremlins out? Thx.
