Lock Out Relay
Before continuing, Refer to Testing the Interlock Relay
procedure in this section. This is an external test to confirm if
the relay is functioning properly.
This test should only be performed if it has been
determined that the relay is not closing by the procedure
indicated above
.
1. Remove the charger
form the vehicle.
2. Remove the charger
cover.
3. Disconnect the black
and white relay coil
wires from the relay.
4. Measure the resistance across the relay coil terminals.
• 120 volt charger: 2,700 Ohms (nominal)
• 220 volt charger: 11k Ohms (nominal)
If out of specification then the relay is faulty.
4. Reconnect the wires to the relay.
5. Disconnect the Violet/Black wires from the relay.
6. Connect an Ohm meter across the relay terminals.
7. Connect the charger AC wires to a power outlet. The relay
should “click” and the meter should indicate a closed circuit.
• If the relay does not “click” then check the wiring to
the relay coil.
• If the meter does not indicate a closed circuit, then
the relay is faulty.
• If the relay tests OK, check continuity of the Violet/
Black wires.
8. Disconnect then charger from the AC power source and
remove all test leads.
While connected to an AC outlet, the charger cabinet
must remain electrically grounded. Disconnect both
of the battery leads and unplug the charger from
the AC source before disconnecting any electrical
component or wire. Failure to do so may result in
serious bodily injury.
Transformer
1. Remove the charger from the vehicle.
2. Remove the charger cover.
3. Connect an AC volt meter to the transformer secondary
winding accessed at the Cathode on each SCR (blue and
violet wires). Set the meter to read up to 150 volts RMS.
4. Connect the charger AC wires to a power outlet.
5. Depress the Low Voltage Start switch and record the
voltage indicated on the meter.
6. Disconnect the charger from the AC power source and
remove all test leads.
7. The transformer secondary RMS AC voltage should
be approximately 2.1 times the rated DC voltage of the
charger.
Note: Typically, the secondary voltage of a failed
transformer will be significantly below specification.
Make sure that the meter leads do not touch any
other component or wire. Other components will be
damaged if the leads touch any other component
or wire.
High Voltage inside the charger. Do not touch any
internal components while the charger is plugged in.
Touching internal components may result in electric
shock causing severe bodily injury or death.
