Check Procedure 12 -- Battery Discharge Meter - Tomberlin 2010 E-Merge Maintenance Manual

5. Turn Tow/Run switch to RUN.
6. When the battery is connected, use a multimeter set at 200V DC, connect the black (-) probe to the
negative binding post of Battery 6 and connect the red (+) probe to the disconnected red terminal of
the reverse buzzer. The voltage reading should be approximately 48V (the battery is fully charged).
7. If the voltage reading is correct, go to Step 12.
8. If the reading is 0, check the continuity of the red wire and Tow/Run switch. Refer to "Check
Procedure 4 - TOW/RUN switch".
9. If the continuity reading is not correct, repair or replace the red wire.
10. If the continuity reading is correct, continue with the following operations.
11. Turn Forward/Reverse gear switch to REVERSE position. Use a multimeter set to 200V DC,
connect the red (+) probe to the positive binding post of Battery 1 and connect the black (-) probe
to the brown/yellow wire of the output line of the buzzer. The voltage reading should be
approximately 43V.
12. If the reading 0V, check the brown/yellow wire for continuity and the connection of Pin P10 of the
9-wire connector.
13. In case of un-continuity of the brown/yellow wire or improperly arranged Pin 10 of the controller,
repair or replace the part as required.
Check Procedure 11 -- Battery discharge meter
Please refer to Chapter 1 "Protection for Electrical Safety".
The main cable has three wires connected to the battery discharge meter: red wire (connected to
Tow/Run switch), red/green wire (connected to key switch) and black wire (connected to the negative
terminal of the battery pack).
Check as follows with a multimeter:
1. Turn Tow/Run switch to RUN, use a multimeter set to 200V DC, connect the red (+) probe to the red
wire and connect the black (-) probe to the negative binding post of Battery 6. The voltage reading
should be 48V. If the voltage is 0V, check the continuity of the red wire and Tow/Run switch.
2. Turn Tow/Run switch to RUN and turn the key switch to ON, use a multimeter set to 200V DC,
connect the red (+) probe to the red/green wire and connect the black (-) probe to the negative
binding post of Battery 6. The voltage reading should be 48V. If the voltage is 0V, check the
continuity of the red/green wire and key switch.
3. Check the continuity of the black wire and the battery pack.
If the three wires are ok and the battery discharge meter displays nothing, replace the battery
discharge meter.
