F650 forum – Battery draw drain
Worth reading the lot, but the salient points (in amps e.g. 0.04 = 40mA) are:

On the GS models, there is also some drain caused by the ECU. You can here some clicking noises for quite a while, after switching off the ignition and I don’t mean from the engine cooling down.

I also checked the draw on initial connection of the battery and like you state the bike must have a small initial systems check or power up as the draw then can be as much as 1-1.5 amps but after 2 mins it settles down to just the 0.04 as previously mentioned.

Some more interesting figures and facts
The instrument console on the 2000-2003 is not fuse protected
ECU disconnected also all fuses removed = inital connection = 0.085 draw = after 2-3 mins = 0.001 draw
everything reconnected = inital connection = 0.13 draw = after 2-3 mins = 0.04 draw
So clock / instrument draws only 0.001 amp at rest
ECU draw = 0.03 amp at rest.
So, in this case, measured current drain was 0.04A (40mA) most of which was the ECU.

mA, I would hope!
What Cougar means is:
mA is milliamp – 1000 th of an amp
MA is mega amp 1 million amps
