36V Battery Box Inspection and Troubleshooting

If the battery range on your 36V Motorized Hand Truck or Motorized Dewar Cart is diminished or if it is

not working at all, there is most likely a problem with the batteries and/or recharging function. It is

typically one of three issues:

1. The batteries are old and need to be replaced – see battery replacement manual. The typical life

is 12-14 months for a set of batteries

2. The charger itself is damaged or there is no power to the outlet that the charger is plugged into.

3. The in line fuse on the re-charge circuit may be blown, and therefore will not allow the charger to

recharge the batteries. Since the battery pack can be recharged on or off the machine, there are

two in-line fuse circuits – one of the machine, and one on the battery pack itself. See below:

STEP 1 – Determine System Voltage at Throttle Charge Port:

Put a volt meter at the charge port on the throttle as shown below. Connect the red lead to Pin 1 and

the black lead to Pin 3. With the meter on volts DC, you should read at least 33 to 38 volts.

If the reading is below 30 volts, check battery pack in Step 2.

If the reading is zero, skip to Step 3 to check the in-line fuse circuit on the machine. DO NOT PLUG

CHARGER INTO BATTERY PACK CHARGE PORT UNTIL YOU CAN DETERMINE IF THE IN LINE FUSE ON

THE MACHINE HAS BEEN BLOWN OR NOT.
