8. Charge interlock relay JDac and associated wiring loose or faulty. Adjust or Replace.
9. Switch on Chinese charger (blue and silver) turned off.
10.AC Power cord to Delta-Q charger (yellow and black) unplugged. Reconnect and wrap in
waterproof electrician's tape to prevent from coming apart again.
11.Defective Charger. You will have either the blue and silver Chinese charger or the yellow
and black Delta-Q charger.
12.The Chinese charger will light the four lights in sequence as it goes through its different
charging stages and ends with the cooling fan off and the red light closest to you lit in red.
This is described in your separate charger manual.
13.For the Delta-Q charger there is no fan so don't listen for this. You may get the Delta-Q
manual at http://www.delta-q.com/documents/QuiQ-data-sheet.pdf. When 80% charged the
80% light (4
th
from bottom) comes on and when fully charged the green light (3
rd
from
bottom) comes on. The 2
nd
light from bottom indicates that the charger is plugged into the
AC outlet and if the bottom red light is flashing there is a fault (most likely the red main
disconnect switch is off. The upper six lights indicate the amount of charging current.
Test charger and batteries:
To test the charger:
1. Run the vehicle until the batteries are very discharged.
2. Connect your Kill-A-Watt meter (available from Zap) to an AC outlet.
3. Plug the vehicle into the Kill-A-Watt meter.
4. Wait for the charging cycle to complete. This is indicated by two yellow lights, one red light
(middle light) and no fan operation for the BC2-7215B. The Delta-Q illuminates the full
battery light. Note, the Delta-Q does not have a fan because it is fully sealed.
5. Press the kWh button on the right of the Kill-A-Watt meter.
6. The reading should be 4.5 kWh or higher depending on how discharged your batteries were
before you started charging. For the larger Discover EV12A-A the energy should be above 9
kWh.
7. If below 4.5 (or 9.0) kWh your charger might not be working properly or your batteries
could be bad.
To check your battery voltages:
1. After the full charge, turn your heater on for several minutes.
2. While the heater is running, check the voltage of each battery with a digital volt meter.
3. Each reading should be around 12.65 or higher.
4. Also important is that your lowest reading battery is not more than 0.10V lower than your
highest reading battery.
5. Consider adding PowerCheq modules (five required) to keep your batteries equalized and
greatly extending the life of the batteries.
6. Any batteries with voltages lower than the above may be bad.
Inadequate charge or range:
How are you driving? Drive style will affect range more than anything else. See how to extend your
range.
1. Make sure you get to the end of your charging cycle. You may have to unplug and re-plug to
get the charger to restart.
