Cart Power/Battery Issue
Loose cord connection
Ensure that all cords are properly plugged
into the AC Rack Power Strip (vertical power
strip inside cart’s rear door) and into the AC
Power Distribution Unit (accessible under the
5-Bay Battery Charger drawers).
If the cart has been stored with
the breaker (located in the belly
compartment) in the ON position
without connection to AC power
during that time, the batteries may
be too low to power your system.
