AC CIRCUIT CHECKOUT PROCEDURE
FOR SINGLE INPUT VOLTAGE CHARGERS
Check for proper input voltage to primary of transformer. Set meter to read AC voltage.
ACTION MEASURE IF THEN
Step 1 – Place AC voltage test leads of
meter at wall receptacle.
Measure voltage
100-130 volts AC
No Check wall breaker or
fuse.
Step 2 – Remove cover.
Step 3 – Place one meter test lead on
the varistor leg that connects to
white wire of AC cord. Place the
other test lead on the charger circuit
breaker terminal that is connected to
black wire of AC cord.
Step 4 – Plug AC cord into wall
receptacle. Measure voltage and
unplug.
Measure voltage
100-130 volts AC
No Replace AC cord.
Step 5 – Keep connection at varistor
leg as in Step 3. Move circuit breaker
connection to the other terminal of
circuit breaker.
Step 6 – Plug AC cord into wall
receptacle. Measure voltage and
unplug.
Measure voltage
100-130 volts AC
No Replace circuit breaker.
Step 7 – Plug DC connector into
receptacle.
All LED’s will flash
through the self
diagnostic sequence
No Perform DC circuit
checkout procedure.
Step 8 – Place meter test leads on
terminals A & B of relay.
Step 9 – Plug AC cord into wall
receptacle. Measure voltage and
unplug.
Measure voltage 90-
130 volts AC
No Check wire harness of
#4 pin connector on
circuit board. If O.K.
replace circuit board
and retest.
Step 10 – Place on meter test lead at
varistor leg as in Step 3. Place the
other meter test lead at "NO"
terminal of relay.
Step 11 – Plug AC cord into wall
receptacle. Measure voltage and
unplug.
Measure voltage 90-
130 volts AC
No Replace relay.
