Is charger connected to A.C.? If NO connect to a good A.C. Circuit

Verify there is A.C. power at the charger. Does the A.C. L.E.D. light?

Is any Green or Yellow LED flashing?

Replace Battery Charger

FAULT CODES EXPLAINATION (RED led Flashing)1 FlashOpen battery cell or open circuitCheck the batteries and wiring. Once the fault is cleared the charger will auto reset. 2 FlashesLow battery voltage was sensedBad Battery or loose connctions. Charger will not start if the battery voltage is too low3 FlashesCharger charge cycle timed out. Once the fault is correected the charger must be unplugged from AC power and wait minimum of 30 seconds and then reconnectWas a different batterysize or type just installed? If so check to make sure battery is for this machine. Was the ambient temperature hotter than normal. If so insure the charger is not over heating. Insure good ventalation and cooling fins are clean. If everything is OK Repalce Charger4 FlashesCharger could not complete the final charging stageCheck batteries for bad cells or low water and battery wiring. If no problem found Replace Charger5 FlashesCharger has reached maximum internal temperature Once the fault is corrected the charger must be unplugged from AC power and wait minimum of 30 seconds and then reconnectWas the ambient temperature hotter than normal. If so insure the charger is not over heating. Insure good ventalation and cooling fins are clean. If everything is OK Repalce Charger6 FlashesCharger Internal Fault Charger. Once the fault is corrected the charger must be unplugged from AC power and wait minimum of 30 seconds and then reconnectCheck batteries, Check battery connections, With A.C. power OFF, check continuity between the Green wire Red wires on the D.C. Output. If no continuity fuse blown Repalce Charger

Battery charger is OK Go to final verification Box Page 4

FROM PAGE 2 Final Verification

As a final verification check of the charging system

1. Disconnect AC power from the battery charger

2. Turn key switch ON and verify machine functions work

3. Connect AC power to the battery charger

4. Verify Charger goes through the initialization stage

5. Verify that all machine functions turn OFF

6. Use a current meter to verify at the battery pack the charger is putting out the Amperage displayed on the charger. If not check wiring

No

FROM PAGE 2 A.C. LED

1. Check Battery Connections

2. Check Open Battery Voltage
