thank you kurt, i was thinking exactly the same....
and with a running engine you are giong to have an alt spinning
producing amps (and volts) and is set up on a voltage sensing
circut... most modern cars use a 60 amp alt, but this alt is only
putting out that much power when its sensing that the battery its
hooked to is dead (and still has enough voltage to excite the
circuit). i dont have a problem with jumping a bike with a running
engine, as long as it a 12v (nominal) source.. dont pull from a 24v
truck or bus circuit, or a 6v golf cart battery (unless you are
doing it in pairs)... i also go against what most books tell you and
hook directly to the battery, not positive to positive and then
negitive to ground..
The books tell you this for YOUR safety not the Bikes. The last
connection is the one that could spark, IF you have a hydrogen
buildup at the battery when you make this spark bad things could
happen. Making the ground (should be last) connection to the frame or
engine does 2 things. If moves this spark away from the hydrogen
source and eliminates 2 possible bad connections. If your ground
cable to the battery, or engine is bad then putting the jumper cable
on the engine eliminates this problem from getting you running again.
Most bikes do not have enough plastic installed during a jump start
to hold any hydrogen so it's safer to buffer the jump start with the
bike's batt.

Some people try to turn back their odometers. Not me, I want people
to know "why" I look this way. I've traveled a long way and some of
the roads weren't paved.
