Section V. TROUBLESHOOTING
Refer to TM 9-6115-643-24 for generator troubleshooting procedures and to TM 9-2815-254-24 for engine troubleshooting
procedures. In this section a symptom index for the kit lists faults associated with kit operation. The kit has an indicator light,
which flashes in a sequence to indicate faults. These pulses are shown visually on the Function Codes plate mounted inside
the generator control panel cover. Refer to Figure 3-1 and 4-2 for the Function Codes plate. Figure 4-3 through 4-19 show the
same information for the kit. Each malfunction listed on the Symptom Index includes a reference to the troubleshooting
figure that contains a chart that will help you determine probable causes and corrective actions to take. The symptom index
cannot list all faults that may occur, nor all the test or inspections and corrective actions. If a malfunction is not listed or
cannot be corrected by listed corrective actions, notify next higher level of maintenance for assistance.
SYMPTOM INDEX, WINTERIZATION KIT
NOTE
When the heater is switched on, the light will perform one of the
sequences of light pulses shown visually on the Function Codes Plate
mounted inside the generator control panel cover (Figure 4-30). Before
each symptom, this index lists in parentheses the light sequence
associated with it.
