Buzzaround_SG_REVA_040711
Component: 12VDC/12AH Batteries (2)
Location: Connected in series inside the battery box.
Function: Supply 24VDC to the motor and/or accessories (12VDC x 2).
Connections: BAT+ and BAT- are located on each battery. BAT1 – BAT3 are located on the outside of battery box.
Failure Signs: Batteries drain quickly. Scooter runs slowly or not at all. Batteries will not charge, but charger is working
properly. Beep Codes #2 and #3.
Tests: Load test. Fully charge the batteries first. Make sure the charging system is working.
See Charger Tests on page 13.
Expected Readings: 12 - 14VDC each when fully charged. 24VDC at BAT1 and BAT3.
Serviceable: Replace battery.
Component: Circuit Breaker (CB)
Location: Mounted on the inside front of the battery box.
Function: Protects battery circuit from current overload. When the current draw exceeds breaker rating, the circuit
breaker will open.
Connections: CB1 and CB2 are the terminals on the circuit breaker. CB3 – CB6 are the terminals on wires that connect
the circuit breaker to the batteries.
Failure Signs: Opens repeatedly. May indicate a failed circuit breaker or short in the wiring. Also, may open if the motors
are overloaded (from excessive weight, excessive uphill driving, etc).
Test: Measure resistance across CB1 and CB2. Check for continuity across CB3 and CB4 and across CB5 and CB6.
Expected reading: Less than 10 ohms.
Serviceable: Circuit breaker must be replaced with exact current rating. Replace wires as necessary.
Component: Battery Charger (BC) (Model: HP1202B, off-board charger only).
Location: Stored inside a pouch on the seat back.
Function: Recharges batteries. There is one LED on the charger. The LED is red when the charger is plugged into an
electrical outlet. If the LED does not go on, then check the electrical outlet. When the charger is on and plugged into the
charger port, an orange LED indicates that the batteries are charging. A green LED indicates that the batteries are fully
charged.
Connections: C1 (connects to CH1 on battery box).
Failure Signs: LED does not go on. Batteries will not charge.
Tests: Test for voltage. Test by measuring positive and negative leads on the charger connector (C1).
Expected reading: 24.5VDC - 27VDC
Serviceable: Replace if necessary.
Component: Charger Harness (CH)
Location: Inside the battery box.
Function: Provides external charger with connection to intermediate charger harness.
Connections: CH1 charger port and CH2 connects to intermediate charger harness.
Failure Signs: Batteries will not charge.
Tests: Test for voltage across Pin 1 and 2 on CH1. Also, test continuity between CH1 and CH2.
Expected readings: Total battery voltage.
Serviceable: Replace as necessary.
Component: Intermediate Charger Harness (ICH)
Location: Inside battery box.
Function: Provides charger harness with connection to batteries and inhibit signal to battery box terminals.
Connections: ICH1 – ICH6
Failure Signs: Batteries will not charge.
Tests: Test for voltage across Pin 1 and pin 2 ICH1. Also, test continuity between pin 3 on ICH1 and BAT2.
Expected readings: Charger will not work when battery voltage is too low. Replace if opens are found.
Serviceable: Replace as necessary.
