BEEP CODE #2 – LOW BATTERY VOLTAGE
The battery needs charging or there is a bad connection to the battery. Check the connections to the battery. If the
connections are good, try charging the battery.
1) Charge the batteries.
2) If the batteries will not charge, then open the battery box.
3) Check for loose or corroded battery terminals. Clean with steel wool or wire brush and tighten if necessary.
4) Measure voltage at BAT- on one battery and BAT+ on the other battery. Take measurement at terminals connected to
the circuit breaker (CB3 and CB6).
• 16 – 24VDC (or battery voltage)? – Replace the intermediate charger harness (ICH).
• 0VDC? – Go to the next step.
5) Measure resistance across the circuit breaker terminals (CB1 and CB2).
• OPEN? - Replace the circuit breaker.
• Less than 1 ohm? - Check the continuity between CB3 and CB4 (red wire) and between CB5 and CB6 (black wire).
Replace as necessary.
BEEP CODE #3 - HIGH BATTERY VOLTAGE
An excessive voltage has been applied to the S-drive. This is usually caused by a poor battery connection. Check the
battery connections. NOTE: The error may only be present when going down hill and power goes back to the batteries.
1) Insert the key into the key switch and turn it to the on position. Allow the battery level to drop. Do not allow the battery
voltage to fall into the red area on the battery meter.
2) Check the battery charger. Make sure it is an approved charger.
BEEP CODE #5 – SOLENOID BRAKE TRIP
The parking brake has a bad connection. Check the parking brake and motor connections. Make sure all the system
connections are secure.
1) Make sure that the scooter is in drive mode. If it is in drive mode, then go to the next step.
2) Separate the front and rear halves of the scooter.
3) Measure resistance across IMH3 (orange wire) and IMH5 (blue wire) on the intermediate motor harness located on the
rear frame.
• Less than 80 ohms but not shorted? - Go to step 8.
• Outside that range? - Go to the next step.
4) Unplug the intermediate motor harness (IMH1) from the motor harness (MT1). Are the pins on the connectors seated
correctly?
• Yes? – Go to the next step.
• No? – Reseat the pins, reconnect IMH1 to MT1, and try to run the scooter.
5) Measure resistance across pin 3 (orange wire) and pin 4 (blue wire) on the motor harness (MT1).
• Less than 80 ohms but not shorted? - Replace the intermediate motor harness (IMH).
• Outside of range? – Go to the next step.
6) Unplug the motor brake (MB1) from the motor harness (MT2). Are the pins on the connectors seated correctly?
• Yes? – Go to the next step.
• No? – Reseat the pins, reconnect MB1 to MT2, and try to run the scooter.
7) Measure resistance across pin 1 and pin 2 on the MB1.
• Less than 80 ohms but not shorted? - Replace the drivetrain.
• Outside of range? – Replace the park brake.
8) Make sure the scooter is completely reassembled.
9) Turn the scooter onto its side.
10) Remove the controller cover.
