Scenario 1: No Power

You insert the key into the key switch. But the battery condition meter indicates no battery power and the
status LED does not go on.
1) Check the circuit breaker (CB.)
• Tripped? – Reset it. If it resets, then operate the scooter.
• Not tripped? – Go to the next step.
• Does not reset? – Go to step 4.
2) Remove the battery box from the scooter.
3) Measure voltage across BAT1 and BAT3 on the outside of the battery box.
• 0VDC? – Go to the next step.
• 12 – 17VDC? – Recharge and load test batteries. Replace if necessary. Go to "Charger Tests" if the
batteries will not charge.
• 18VDC – 25VDC? – Go to step 8.
4) Open the battery box.
5) Check for loose or corroded battery terminals. Clean with steel wool or wire brush and tighten if necessary.
6) Measure voltage at BAT- on one battery and BAT+ on the other battery. Take measurement at terminals
connected to the circuit breaker (ICH2 and ICH6.)
• 18 – 25VDC (or battery voltage)? – Replace the intermediate charger harness (ICH.)
• 0VDC? – Go to the next step.
7) Measure resistance across the circuit breaker terminals
• 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.
8) Reinstall the battery box.
9) Open the front console.
10) Disconnect the main harness (MH2) from the tiller board (TB1) Are the pins on the connector (MH2) seated
correctly?
• Yes? – Go to the next step.
• No? – Reseat the pins, reconnect the main harness to tiller board, and try to run the scooter.
11) Check the connector (TB1) on the console board. Is it loose on the board?
• Yes? – Replace the console board.
• No? – Go to the next step.
12) Measure voltage across pin 3 (black wire) and pin 8 (red wire) on MH2.
• 18 – 25VDC (or battery voltage)? – Go to the next step.
• 0VDC? – Go to the step 16.
12) Reconnect MH2 to the tiller board.
13) Remove the tiller board from the top half of the console.
14) Disconnect the key switch (KS1) from the tiller board. Are the pins on the connector (KS1) seated
correctly?
• Yes? – Go to the next step.
• No? – Reseat the pins, reconnect the key switch to the tiller board, and try to run the scooter.
