Hello,  New to forum.  I have an 03' 650 LS Savage with less than 4500 miles on odometer.  If the bike sits for 3-4 days w/o being operated, the battery gets drained down to such a point that it will not turn over to start.  I bought a new battery approx 2 months ago, charged it and the bike still doesn't hold a charge.  

Is there some circuitry on bike that could be draining power from battery when it is off or is this more of a charging problem.  If so, any suggestions as to how to isolate and determine what is causing this problem?

Thanks for any help that can be offered.

I'm thinking there's a drain somewhere.  Mine has sat for a couple weeks and started with no trouble.  Most of my trips tend to be short 1 to 3 mile and I haven't had to put a charger on mine in the almost 2 years I have had it. Standard wet cell battery.

Like Serow said, are there any accessories installed that might be eating power when supposed to be off?

If the battery is not connected, will it still go dead in a couple days? If so, it's a battery problem. If not, it's something on the bike.

If you've got a meter with an amp scale on it, connect it between the battery and the + lead to the bike.  With the key off, it should read 0. Anything over 0 and something is pulling power.

Also, you've probably already done this but make sure you are turning it off and not to park which will leave the tail light on.

Do you have the battery going dead problem if you ride the bike every day or every other day?
