Is my GPS draining my battery?
I've got a BMW1200GS and a Zumo 660 GPS. I've connected the GPS straight to the battery. I've noticed that when I turn the bike off the GPS doesn't turn off (as it's connected directly to the battery, I assume). I think this is a good thing but I'm worried about what it might mean.
I assume it means it's drawing a tiny bit of electricity from the battery but I'd need to leave it on for days/weeks for it to kill the battery. I'm happy to leave the GPS turned on all day and make sure I physically turn it off if I'm leaving the bike for a while (in fact I'll take the GPS off the moutn and take it with me anyway.)
But what about when I take the GPS off the mount? When the Zumo 660 is removed from the mount is the mount still drawing power?
I've looked online but the answers are all too technical for me. There is some talk of needing an 'inline fuse'. I think there's one built in to the wiring on the 660 but am not sure. I'm worreid because I put my GPS in last autumn and my battery died over the winter. I've just put in a new battery and hooked it all up today. I don't want the same thing to happen.
