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.
See following DANGER.
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 6-6, Page 6-12)
.
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 white or blue wire of AC cord at terminal on control board
(Figure 6-8, Page 6-13)
.
See fol-
lowing DANGER.

3. Place black (–) probe of multimeter, set to 500 volts AC, onto terminal with black wire from relay. Connect
red (+) probe to terminal from which the white or blue AC cord wire was disconnected
(Figure 6-7,
Page 6-12)
