IF AN ELECTRICAL SHORT EXISTS, ELECTRICAL CURRENT CAN BECONDUCTED FROM THE BATTERY SUPPORT, THROUGH THE FRONT BRAKE LINES TO THE FRAME.ON MOTORCYCLES WITH ANTI-LOCK BRAKES (ABS) THIS MAY 1) CAUSE THE BRAKE FLUID TOINCREASE IN TEMPERATURE WHICH COULD IMPAIR FRONT BRAKE PERFORMANCE; AND 2)MELT A HOLE IN THE FUEL TANK CAUSING A LEAK WHICH COULD RESULT IN A FIRE. ONMOTORCYCLES WITHOUT ABS, DAMAGE TO THE CIRCUITRY IN THE ELECTRONIC ENGINECONTROL UNIT MAY OCCUR, CAUSING AN IRREGULAR-RUNNING ENGINE.

REMOVE THE POSITIVE TERMINAL EXTENSION AND ATTACH THE POSITIVE BATTERY CABLE CONNECTOR DIRECTLY TO THE BATTERY TERMINAL WITH A BOLT.

VEHICLES OPERATED UNDER THIS INCREASED COOLING SYSTEMPRESSURE CONDITION CAN SUFFER DAMAGE OR FAILURE OF PARTS OF THE COOLING SYSTEMSUCH AS (1) LEAKAGE FROM A COOLANT HOSE, (2) LEAKAGE OF THE RADIATOR OREXPANSION TANK, (3) DISCONNECTION OF A HOSE FROM A PIPE OR A FITTING, AND (4)CRACKS IN THE HEATER CORE END PIECE RESULTING IN COOLANT LEAKAGE. IN SOME CASES,BOILING COOLANT CAN CONTACT THE LOWER RIGHT LEG OF THE DRIVER RESULTING INBURNS. ALSO, ESCAPING COOLANT IN THE PASSENGER COMPARTMENT CAN CAUSE VAPORFOGGING OF THE INTERIOR SURFACE OF THE WINDOWS, REDUCING DRIVER VISIBILITY.

DEALERS WILL INSTALL A THERMOSTATIC BYPASS VALVE IN THE ENGINE COMPARTMENT TO CONTROL COOLANT TEMPERATURE IN THE HEATER CORE. ALSO, A NEW DESIGN RADIATOR CAP WILL BE INSTALLED, TO CONTROL PRESSURE AND PROVIDE GREATER COOLANT OVERFLOW IN THE EVENT OF OVERHEATING.
