Component
: 50 amp Circuit Breaker (1)
Location:
Mounted on the front frame under the seat. See
figure 1.
Function:
Protects battery circuit from current overload. When
the current draw exceeds the breaker rating, the circuit breaker
will open.
Connections:
The circuit breaker is connected to the power
harnesses (6b and 7b.)
Failure Signs:
Opens repeatedly. May indicate failed circuit
breaker or short in the wiring. May also open if the motors are
overloaded (from excessive weight, short in system, etc.)
Test:
Measure the resistance across the circuit breaker.
Expected reading:
Less than 10 ohms.
Serviceable:
Circuit breaker must be replaced with exact
current rating.
Component:
12VDC/U-1 Batteries (2 and 3)
Location:
Connected in series under the rear shroud. See
figure 2.
Function:
Supply 24VDC to the motor and/or accessories
(12VDC x 2)
Connections:
Positive (+) and negative (-) terminals connect to
the Battery Harnesses (4 and 5).
Failure Signs:
Batteries drain quickly. Scooter runs slowly or
not at all. Batteries will not charge, but charger is working
properly. Flash Code #1 or #2.
Tests:
Fully charge the batteries first and load test. Make sure
charging system is working. See Battery Charging Test.
Expected Readings:
12 - 14VDC each when fully charged.
Serviceable:
Replace batteries as necessary.
Component:
Battery Harnesses (4 and 5)
Location:
Connected to the positive (+) and negative (-)
terminal on the batteries. See figure 2.
Function:
Connects the batteries to the Power Harnesses (6
and 7)
Connections:
4a and 4b connect to the neg (-) and pos (+)
terminals on Battery 2. 5a and 5b connect to the neg (-) and pos
(+) terminals on Battery 3. 4c and 5c connect to the Power
Harnesses.
Failure Signs:
Corroded wires may cause the batteries not to
work properly. Make sure connector pins are seated properly.
Tests:
Check the inline fuse on the battery harness. Test the
harnesses and the 125A fuse for continuity.
Expected Readings:
Less than 10 ohms.
Serviceable:
Replace 125A fuse and/or harnesses as necessary.
