The electrical system consists of two long-lasting, 12-volt, deep-cycle batteries, the onboard battery charger, the charger
ammeter, the self-resetting thermal fuse, and the controller. The batteries sit on the frame, inside the power base. The
charger, the ammeter, and the charger fuse are mounted to the frame. Depending on the controller configuration, the control-
ler may be mounted on the end of the armrest, or on the frame. Refer to the controller insert for more specific information on
your controller.
ELECTRICAL SYSTEM COMPONENTS AND CONNECTORS
Electrical system components and connectors are on or inside the Blast power base. The remote controller, the battery
charger, and the thermal fuse are located inside the power base. See ìRemote Plus Controllerî for controller information. The
ammeter, battery charger AC power receptacle, and the controller harness connector are all located on the front of the Blast
power base. See figure 4.
CONTROLLER HARNESS CONNECTOR:
THIS IS WHERE THE JOYSTICK/KEYPAD
CONNECTS TO THE CONTROLLER.
REFER TO ìREMOTE PLUS CONTROL-
LERî FOR MORE INFORMATION.
AMMETER: DISPLAYS THE CHARGERíS
CURRENT OUTPUT IN AMPS.
BATTERY CHARGER AC POWER
RECEPTACLE: THIS IS FOR THE
BATTERY CHARGER POWER LEAD.
CHARGER FUSE: PROTECTS THE CHARGING
CIRCUIT FROM OVERLOADING.

SELF-RESETTING THERMAL FUSE (LOCATED INSIDE THE POWER BASE):
PROTECTS THE BATTERY CIRCUIT FROM OVERLOADING. WHEN THERE IS
AN EXCESSIVE STRAIN ON THE BATTERIES FROM STEEP RECLINES OR
HEAVY LOADS, THE THERMAL FUSE WILL REDUCE THE AMOUNT OF
CURRENT GOING TO THE CONTROLLER BY 60%. THE CURRENT WILL
RETURN TO 100% WHEN THE FUSE COOLS TO WITHIN ITS NORMAL OPERAT-
ING TEMPERATURE RANGE.
