John,
If the machine is aged about when alternators first started appearing on
equipment, this is probably the manufacturer's way of protecting the
alternator from reverse polarity connection to the battery when charging or
jump starting.

>Disconnect field!?

I just got a "new' machine today.....and on a decal attached
to the battery box it said "disconnect field before removing, charging, or
jumping battery"

I got into the operator's manual to see why/what was going on and sure
enough they give pretty explicit warnings to disconnect the alternator diode
connection (field connection)

I have never run across this before..!? (to my meager recollection) but
would like some insight as to this particular setup and why it would require
this type of warning.   Is this just an overzealous warning label or is
their a real purpose?

Thanks
