POWERDRIVE CHARGER (ONBOARD)
4. Normal no-load voltage should be between 50 and 52 volts for fully charged batteries. The voltage of the
battery pack must be over 32 volts DC to allow the onboard computer to close the charger relay. If battery
pack voltage is too low to start charger, temporarily bypass the charger relay. See Charging a Battery
Pack that has Low Voltage on page 4-31.
TEST PROCEDURE 2 – CONTROL BOARD
See General Warning, Section 1, Page 1-1.
DC Circuit Test
1. Disconnect AC cord from outlet. DC cord red, black, and blue wires remain connected to the vehicle. All
wires remain connected to the control board. Set multimeter to 200 volts DC.
ý
DANGER
• Do not touch any wire or component in the battery charger while DC power is present. Failure
to heed this warning will result in an electric shock.
2. Place black (–) probe of multimeter on terminal with blue DC cord wire and red (+) probe to terminal with
red relay wire (Figure 4-9, Page 4-12).

3. Multimeter should indicate full battery voltage (approximately 47-50 volts). If reading is incorrect, replace
control board.
AC Circuit Test
1. Disconnect AC cord from outlet. DC cord red, black, and blue wires remain connected to vehicle. Set
multimeter to volts AC.
2. Disconnect tan wire from transformer primary coil at terminal on control board (Figure 4-11, Page 4-13).
