I checked on my sled in the trailer this summer and found the battery to be dead. It wouldn't take a charge, so I bought a new factory replacement, as I needed to take it to my dealer for a new sub frame ( covered by warranty, THANK GOD! About two weeks after getting it home, I go out to the trailer, and it won't turn over. My question is , what might be running it down? Key was off.
This is not my best area but someone should chime in. You could for a start unplug one thing at a time to see if there is a leak like in the cdi or any other electronic component or a short in the wiring. If the leak is that slow I am thinking it is a diode leak from a circuit board. Or maybe something you added on. That said your first battery could still be salvageable by getting a desulphating battery charger and let it do its thing on it. Good luck.

To check for a current draw you need to use a test light or amp meter and place them in line with your negative battery cable (disconnect cable and place test light or meter in between). With a test light it will light up if there is a draw, the meter will show how many amps it's drawing (instead of light), then start removing fuses, if there is no change in draw when you remove a fuse it is not that circuit and you need re-install the fuse and move on to the next fuse, once you find which fuse makes the draw go away you can then narrow it down to what component is causing the issue. This is how we test for a draw in vehicles and may be a little tough on a sled as I am sure the fuse/circuits are limited unlike a car or truck.

Have you tried connecting an amp meter? Its more or less impossible to find electrical leaks without it.. I had a fault on my sled once, the HID lights fired up suddenly even if the ignition was off. That was a problem in the relay harness. Hooked up an extra relay before the HID harness, and no more problems since that.

Battery going dead
Had a similar problem. In my case, it turned out to be a bad backup alarm switch. The alarm didn't beep, but it made enough contact to drained the battery overnight.

It could be the well known wire harness rub at the left front motor mount, if you have not had that taken care of.
