Question re: small drain on battery

[TonyT607]

Guys I just installed all my goodies (Gadget Guy bracket kit, XM Roady, V1, GPS, Givi mounting plate for my V46) on the new ST over the weekend. For a wiring solution I ordered a custom harness from Easternbeaver.com which I wired directly to the battery terminals. The Delphi XM Roady has a 12v > 6v power supply which is always 'hot'. I velcro'ed the unit under the seat and out of the way. This little box has a red LED which is, of course, always ON. Do I need to worry about it slowly draining my battery or is it such a small amount of juice that it would be the equivalent of a clock like on the RR ? Do I need to install a switch/relay ? The other devices don't draw any power when not on.

I've been unscrewing the fuse on the power supply when leaving the bike in the garage.

Thanks !

Tony, my suggestion would be to get a Battery Tender, Jr and keep it plugged in when in the garage. No need for anything larger than the Jr and wire it directly to the battery, also a good place to plug in your Gerbings when needed, will not be a problem with the Can Bus or Computer. The Jr. works great with your AGM battery, by using the Jr hen in the garage, your battery will easily last 5 or more years.

The Bike computer has a small paracitic drain as do some of your goodies, as they say, "an ounce of prevention..............

Great Dean thanks for that. Will do.

I am loving the ST !

I recall that in 1960, while in high school, a schoolmate won some science competition with the following project:

He had a LED, a simple circuit, and a small AA battery mounted on a piece of plastic foam. The whole thing was floating on water, held in a small glass salad bowl. The water/glass bowl was to show there were no other ways for power to get to the light.

The display had been kept in a locked display case in the school so no one could replace the battery. When the guy entered the competition, his LED had been blinking for just over a year - and was still going strong.

That was with 1960 technology, I think one can expect better today. But it never hurts to be sure.
