Troubleshooting
6.6
Power Pack Empty
If the power pack is completely empty, an error-beep
sounds and the BMS disables the throttle. You cannot ride
the motorcycle until you recharge the power pack. If the
Power Pack Empty error-beep still sounds after two hours
of charging time, contact your dealer. Your power pack
may need to be repaired or replaced.
Power Pack Full (High Power Pack-Voltage)
If the BMS detects that the power pack is already full, it
disables any further charging to prevent damage to the
power pack.
This is not an error-condition; it is the result of a successful
charging cycle. There is no self-test flash code which
reports this condition.
During an ordinary charging cycle, when the cells are
balanced, the charger (not the BMS) senses that the
power pack is full and terminates the charging cycle with a
“green light.” The BMS does have a redundant back-up
mechanism to prevent overcharging of the power pack. If
the charger fails to terminate a charging-cycle when the
power pack is full, the BMS will terminate charging itself to
prevent damage.
Power Pack Too Hot
The power pack contains internal temperature sensors. If
the BMS measures excessive internal temperatures, it
flashes an error code and disables the throttle. You cannot
ride the motorcycle until the power pack cools down. Place
the motorcycle in a cool, well-ventilated location and wait a
few minutes before riding again. If the Too Hot error code
still flashes after the power pack has had time to cool
down, contact your dealer. Your power pack may need to
be repaired or replaced.
Power Pack Unbalanced
The power pack contains many individual cells. The BMS
continuously monitors the cells and tries to keep them all
“in balance” (at the same level-of-charge). If any of the
cells are grossly out-of-balance, the BMS flashes a Power
Pack Unbalanced error code and disables the throttle. You
cannot ride the motorcycle until the problem is resolved.
The solution to the problem is to plug in the charger and
allow the power pack to charge for 72 hours. This allows
the BMS to re-balance the cells in the power pack. If the
Power Pack Unbalanced error code still flashes after the
power pack has spent more than 72 hours charging,
contact your dealer. Your power pack may need to be
repaired or replaced.
