4.
As the accelerator pedal is pressed, the voltage reading should increase from approximately 5 volts RMS
when the MCOR limit switch closes, to approximately 48 volts RMS with the accelerator pedal fully pressed.
See following NOTE.
NOTE:
Voltage can vary depending on controller speed setting as well as which zone a Guardian equipped vehicle
is located.
Example:
Speed setting 1 may only read 30 volts.
4.1.
If there is no voltage reading, check the MCOR.
See MCOR Voltage on page 12-22.
Also check the
continuity of the large posts of the solenoid.
See Solenoid Continuity on page 12-20.
4.2.
Disconnect the batteries and discharge the controller.
See Disconnecting the Batteries – Electric
4.3.
Check continuity on A1 and A2 motor terminal posts and continuity of the F1 and F2 motor terminal posts.
Also, check continuity of all motor wires. Section 16 — Electric Vehicle - Motor
TEST PROCEDURE 14 – Voltage at Charger Receptacle Red Wire Socket
See General Warnings on page 1-2.
NOTE:
This is a voltage test.
1.
If necessary, see Testing Basics on page 12-11.
2.
Probe the charger receptacle socket connected to the red, 10-gauge wire. The reading should be BPV.
3.
If the reading is zero volts, check the following items:
– The 30-amp fuse (located near solenoid) in the 10-gauge red wire of the charger receptacle harness.
– Continuity of the 10-gauge red wire from the solenoid to the receptacle socket.
– Continuity of the 6-gauge red wire from the positive post of battery no. 1 to the solenoid.
4.
If the reading is less than BPV, inspect related wiring and connections for tightness, damage and corrosion.
