Component
: Circuit Breaker (1)
Location:
Mounted on the Battery Pack.
See figure 2.
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 positive (+) terminal on one battery and the negative (-) terminal on
the other.
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, excessive uphill driving, etc).
Test:
Measure the resistance across the circuit breaker and the wires that connect the circuit breaker to the batteries.
Expected reading:
Less than 10 ohms.
Serviceable:
Circuit breaker must be replaced with exact current rating.

Component:
12VDC Batteries (2 and 3)
Location:
Inside the battery pack.
See figure 3.
Function:
Supply 24VDC to the motor and/or accessories (12VDC x 2).
Connections:
Connected in series. The positive (+) terminal of one battery is connected to the negative (-) of the
other at the circuit breaker (1) and at the battery harness (4c and 4d). Refer to figure 11 on page 10.
Failure Signs:
Batteries drain quickly. Scooter runs slowly or not at all. Batteries will not charge, but charger is
working properly. Beep Code #1 or #2.
Tests:
Fully charge the batteries first and load test. Make sure charging system is working. See Battery Charging
Test. Make sure the contacts are not corroded. See figure 4 below and figure 19 on page 14 for quarter test.
Expected Readings:
12 - 14VDC each when fully charged.
Serviceable:
Replace batteries as necessary.
Component:
Battery Harness (4)
Location:
Inside the battery pack.
See figure 3.
Function:
Connects the batteries to the Power Harnesses (5).
Provides over current protection from the battery charger
through a 3-amp inline fuse.
Connections:
Connected to the power harness through 4a.
Connected to the charger harness through 4b.
Connected to the batteries through 4c (+) and 4d (-).
Refer to figure 11 on page 10.
Figure 4. Scooter Battery Connection
Failure Signs:
Corroded wires may cause the batteries not to work properly. Make sure connector pins are seated
properly. Batteries will not charge if the inline fuse is blown.
Tests:
Test the harness for continuity. Test the fuse for continuity.
Expected Readings:
Less than 10 ohms.
Serviceable:
Replace the harness as necessary.
Replace inline fuse with exact type and rating.
