Section Il. ELECTRIC WINTERIZATION KIT
The electric winterization kit is used to maintain the engine coolant and lubricating oil at normal operating
temperature in situations which require immediate starting of the generator set. It will function effectively down
to an ambient temperature of -65°F (53. 9°C). The kit consists of a heater assembly, a heater control
assembly, and interconnecting coolant lines and fittings and wiring harnesses. Power for operation of the kit
may be obtained from any 208 to 240 volt, 50/60 Hz or 400 Hz, single phase source.
Table 5-2 contains a numerical list of malfunctions which is useful in diagnosing and correcting unsatis-
factory operation or failure of the electric winterization kit. Each numbered malfunction is followed by an
numerical listing of probable causes of the malfunction. The corresponding listing of corrective actions contains
references to the applicable maintenance paragraphs for correcting the cause of the malfunction.
Refer to the Operator and Unit Maintenance Manual for troubleshooting information
applicable to lower levels of maintenance.
