[QUOTE="Fred W, post: 1126075, member: 3828"] If this is a parasitic drain issue, here's how to find the culprit. Disconnect the negative battery cable. Put your Multimeter in current measurement mode (Ammeter). You'll want to start out on a high scale and then knock it down after you see what's there. Complete the circuit between the negative cable and the battery at the negative terminal with your ammeter. Leave the key OFF for the entire time. When you first make the connection the bike will draw more current as the instrument cluster wakes up and the gauges sweep, but then it should drop down to the very low drain current ionbeam mentioned. If you see much more than a few milli-amps start disconnecting stuff, or pulling fuses, until it goes away. If you do see only a few milli-amps it confirms that you do not have a parasitic draw issue, just an old battery that is discharging internally (you won't read that discharge on your meter). [/QUOTE]
