"Battery Tender" questions
I seem to remember that if you use a "Battery Tender" that plugging it in to a winter stored bike for a couple days a month is just as good as leaving it continually plugged in. The only current draw on my bike is the clock. Any comments? (Mine is a Battery Tender Junior.)
Last year I used the adapter that let me plug the BTJ into the BMW receptacles and it worked perfectly. This fall I did the same, and after three days saw the same solid red light. Finally read the instructions on the charger and "solid red" means "you are not charging the battery." Hmmm. The fuze is good. It would seem that either the connecting cable or the internal wiring of the BMW plug has a fault, but both seem improbable. Any ideas, or exactly how to check?
I DID solve the charging problem by using the little "alligator" connections on the positive battery pole and the ground bolt, both on the left side of the bike.
My electric jacket wiring is now directly connected to the battery so guess I haven't used the BMW sockets for awhile.
R1200RT came with pigtail
My new bike came with a dealer installed pigtail connected to the battery with an SAE connector to accommodate a battery tender unit. I did not request this and only found out about it when I took a pigtail in with me at the 1000 km service. When I asked them to attach it, they showed me their standard item already installed.
I have the Sr unit that has a storage mode - Jr probably does too. Just leave it connected all winter.
Bringing an Odyssey 680 back to life
I have Odyssey 680s in a 1998 R1100 RT and 2005 K 1200 LT. I have a Deltran Tender Junior and Tender Plus. If your Odyssey battery falls below 6.5 volts, you will need a bigger charge than what the Tenders will give you. Some places recommend connecting a parallel battery and then charging. I found that charging with a 10 amp charger for a cycle worked well. After bringing the battery above the 6.5 volt reading the Tenders work well. The Tenders should give you volt readings above 12 volts after they go into float mode.
I use the Tender Junior on the RT once a month for 24 hours and leave the Tender Plus plugged into the LT. The LT will drain the battery. I have have liked the ownership experiences I have had with Odyssey batteries.

What model bike - Multiple plugs?
When I bought my 2000 K1200LT, I also got a Battery Tender. The dealer told me to use the plug outlet by my left knee, not the one on the top case. The top case plug only worked when the bike was running.
If you have more than one plug on your model, that may be the problem.
