Charger Tests
Note: The charger will not work properly if the battery voltage is to low. Boost charge the batteries to bring the voltage up
to a level that the HP1202B off-board charger will see, then plug the charger into the charging port and charge for 8 hours.
1) Make sure that the charger (C) is plugged into a working electrical outlet.
2) Check the charger harness (CH) and the intermediate charger harness (ICH) for loose and/or corroded connections.
Clean or tighten as necessary.
3) Check charger harness (CH) and intermediate charger harness (ICH) for continuity. Replace as necessary.
Scenario 2: Power to Console, but Scooter will not run.
You insert the key into the key switch. The status LED indicates power (but no BEEP code) and the battery condition
meter indicates a full charge. You push the paddle and the scooter does not move.
1) Remove the battery box from the scooter.
2) Measure resistance across BAT 1 and BAT 2 located on the battery box.
• Open? – Go to the next step
• Less than 1 ohm? – Replace the intermediate charger harness (ICH).
3) Open the front console.
4) Disconnect the main harness (MH2) from the top dashboard (TD1).
5) With the key still in the key switch, measure resistance across pin 4 (red wire) and pin 8 (white wire) on TD1.
• Less than 1 ohm? – Go to the next step.
• Open? – Replace the top dashboard.
6) Remove the cover from the controller.
7) Disconnect the main harness (MH1) from the controller (CN7).
8) Measure resistance across pin 7 (red wire) on MH1 and pin 4 (red wire) on MH2.
• Less than 1 ohm? – Replace the controller.
• Open? – Replace the main harness.
BEEP CODES
The S-Drive controller uses audible beeps to indicate the status of the system. When the controller notices that there is a
malfunction in the system, it will beep a code when the power is on. The signal will be a set of fast beeps lasting two
seconds. The slower diagnostic pattern will then be sounded once. For example, when it Beeps five times and stops, that
indicates BEEP code #5 – Brake Trip.
The following BEEP codes are used to help diagnose system errors:
BEEP Code #2 – Low Battery Voltage
BEEP Code #3 – High Battery Voltage
BEEP Code #5 – Solenoid Brake Trip
BEEP Code #6 – Throttle Trip
BEEP Code #7 – Throttle Trip
BEEP Code #8 – Motor Disconnected
BEEP Code #9 – Possible Controller Trip
