BATTERY CHARGER: FOR ERIC CHARGING
SYSTEM
3.1. Verify that the 10-gauge red wire from the charger receptacle is connected to the large post of solenoid
with 6-gauge red wire (Figure 15-5, Page 15-10).
3.2. Verify that the 10-gauge black wire from the charger receptacle is connected to the B- terminal of controller.
3.3. Verify that the 16-gauge light blue wire from the charger receptacle is connected to the light blue wire bullet
connector from the main wire harness.
4. With batteries connected, DC cord disconnected, and using a multimeter set to 200 volts DC, place the black
(–) probe in the charger receptacle socket connected to the black 10-gauge wire and place the red (+) probe in
the charger receptacle socket connected to the red 10-gauge wire. The reading should be 48 to 50 volts (full
battery voltage).
5. If the reading is not 48 to 50 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.
TEST PROCEDURE 3 – Battery Condition Using Charger
The easiest way to monitor the condition of a vehicle's batteries is simply to observe the Charger Status Indicators
on the charger at the end of the charge cycle. After a full charge, disconnect the charger DC plug, wait 30 seconds
and reconnect the charger DC plug. The battery-shaped status indicator will be green with the upper half flashing at
first and then stay on continuously within 10 to 20 minutes, indicating sound, fully charged batteries. See External
Charger Status Indicators on page 15-4.
NOTE: Batteries near the end of their useful lives may not allow the battery charge current to taper and the upper half
of the battery-shaped status indicator will continue to flash. Section 14 — Batteries: Electric Vehicle with
ERIC Charging
Continued poor performance may indicate a problem in the vehicle electrical system, brakes or battery charger. If the
problem is not found in the vehicle or charging system, proceed to the on-charge voltage test. If the upper half of
the battery-shaped status indicator does not stop flashing, the batteries should be tested further using the on-charge
voltage test.
TEST PROCEDURE 4 – On-Charge Battery Voltage Using Charger And Multimeter
When the batteries are fully charged, disconnect the charger DC plug. Wait 20 to 30 seconds and reconnect the DC
plug to restart the charger. After 5 minutes, use a multimeter to check and record the voltage of the battery set as
well as the individual batteries. Set the multimeter to 200 volts DC. Place the red (+) probe on the positive (+) post
of battery no. 1 and the black (–) probe on the negative (–) post of battery no. 6 (for 6 x 8-volt battery set). Record
reading. Then set multimeter to 20 volts DC and place the red (+) probe on the positive (+) post and the black (–) probe
at the negative (–) post of each battery. Record the readings.
The on-charge voltage for the set should be between 56.0 and 63.0 volts depending on the age and state of charge of
the batteries being tested.
Old batteries may have enough capacity left to last several more months.
TEST PROCEDURE 5 – AC Power and Continuity Test of AC Circuit
1. Disconnect AC cord from the wall outlet and DC plug from the vehicle receptacle.
2. Check the AC line fuse or circuit breaker in the storage facility.
