Re: Stupid battery question
On the LT you should either use one of the powerlet plugs, or hook BOTH leads to the battery. There is no reliable frame ground on the LT, as BMW does not use frame as ground, but runs brown ground wires to everything. Using the frame for ground for any purpose can lead to problems, or just plain unreliable ground reference to the battery. I learned that on my first LT, the hard way. Kept getting bad intermittent problems when trying to add devices and using frame grounds. Even if you get a ground, it may be a relatively high resistance circuit, or intermittent.
If you look behind the battery you will see a ground lug that has a couple brown wires on it with the negative wire from the battery, and you will also notice that it is INSULATED from the frame.
