The XM2 batteries are isolated from chassis ground by design. Any voltage potential difference between battery (-)
and chassis ground must be eliminated before installing the transponder to avoid potential transponder damage. To
accomplish this, attach a ground jumper between battery (-) and chassis ground before installing the transponder. Once
the transponder is installed the jumper may be removed if desired.
