Thanks, guys. Well, I put a multi-tester on my battery and it's deader than a rat after 24 hrs on the trickle charger. Calls to the two Honda dealers here produced quotes of $70 and $90 for a replacement (14 Amp Hour)battery. The Rocky Mountain catalog showed that they now recommend a 20 AH battery, so I got the larger battery for $48 plus $7 shipping.
Incidentally, I had your same experience with the bolts loosening from the battery terminals. At first I used Loctite, but now I use a glob of "Household Goop" (purple label) on the side of the bolt head. This stuff is great. Pick up a tube at Home Depot and you'll find a hundred uses for it. It dries just barely pliable but is really tough stuff. Much tougher than silicone caulk.
