First question: Why would you tack THIS question on the end of an OIL discussion ?? :huh:
Someone familiar with the Intruder will be along shortly but I suggest that you consider just getting a NEW battery, since you don't know the age or history of the one that is in there now.
Also you should get the charging system checked. A battery store (or a dealer) should do that for you for little or no charge; it only takes a few seconds.
Maybe charging it enough to get it going and then riding it to a battery store would be the best way to go. :bluethum:
