TEST PROCEDURE 2 – Onboard Computer Solenoid Lockout Circuit
See General Warnings on page 1-2.
The solenoid lockout circuit disables the vehicle when the battery charger is plugged into the vehicle. Use the following
procedure to test the solenoid lockout circuit:
1. With batteries connected, place the Tow/Run switch in the RUN position.
2. Using a multimeter set to 200 volts DC, place black (–) probe on battery no. 6 (6 x 8-Volt battery set) negative
post and red (+) probe (with insulation-piercing probe) on the light blue onboard computer wire (at a point
between the OBC and the six-pin connector). The reading should be approximately 42 to 46 volts (full battery
voltage). If the reading is not 42 to 46 volts, proceed to step 3. If the reading is 42 to 46 volts, proceed to Test
Procedure 3 – Solenoid Activating Coil on page 13-15.
3. Place insulation-piercing probe on the light blue 18-gauge wire at a point between OBC six-pin connector and
main wire harness. If reading is 42 to 46 volts, check the wire terminal connectors inside six-pin connector at
OBC six-pin connector. Make sure pins are properly aligned inside housing. Make sure wire colors match and
are connected to the correct terminals.
4. If reading is zero volts, plug the charger DC cord into the vehicle charger receptacle. If the dash light illuminates
for 10 seconds, the OBC is now powered-up. Unplug the DC cord; the reading at the OBC light blue wire should
be approximately 42 to 46 volts. If the vehicle now operates normally, the DC cord has powered up the electrical
system. The electrical system should also power-up when the accelerator pedal is pressed. To check the
accelerator pedal function, see Test Procedure 4 – MCOR3 Voltage on page 13-16.
5. If the dash light illuminates for 10 seconds and the vehicle does not operate:
5.1. Using a multimeter set to 200 volts DC, place black (–) probe on battery number 4 and place red (+) probe
(with insulation-piercing probe) on light blue 18-gauge wire at OBC six-pin connector.
5.2. With Tow/Run switch in the RUN position, the voltage reading should be approximately 48 volts.
6. If the dash light does not illuminate and the vehicle does not operate, check the OBC activation circuit.
6.1. Using a multimeter set to 200 volts DC, place the black (–) probe on the battery no. 6 (6 x 8-Volt battery
set) negative post and place the red (+) probe (with insulation-piercing probe) on the red 18-gauge wire
located on the OBC side of the six-pin connector. The reading should be approximately 48 volts. If the
reading is incorrect, test the Tow/Run switch and connecting wires.
See Test Procedure 6 – Tow/Run
Switch on page 13-19.
6.2. Using a multimeter set to 200 volts DC, place the black (–) probe on the battery no. 6 (6 x 8-Volt battery set)
negative post and place the red (+) probe (with insulation-piercing probe) on the red 18-gauge wire (harness
side of six-pin connector). Multimeter should indicate 48 volts. If voltage is correct, check connections in
the six-pin connector. If connections are correct, OBC activation circuit has failed. Replace OBC.
TEST PROCEDURE 3 – Solenoid Activating Coil
See General Warnings on page 1-2.
NOTE: Be aware that one of two different solenoids may be found on the vehicle. Visually, the production solenoid is
smaller than the service replacement. On the labels, the larger service replacement solenoid has SOL0605
and the smaller production solenoid has SOL5006. Internally, specifications and test results differ between
the two.
1. Disconnect the batteries and discharge the controller. See Disconnecting the Batteries – Electric Vehicles
on page 1-4.
2. Access the solenoid by removing the electronics module cover. See Electronics Module Cover on page 14-5.
3. Remove the two small wire terminals from the solenoid.
4. Place red (+) probe of the multimeter on the positive (+) solenoid terminal. Place the black (–) probe on the
other small solenoid terminal.
