REFERENCE #7
Input voltage has not reached 13.8 volt turn-on threshold. Follow
the steps below to diagnose.
Step 1: With the reefer running and the stinger and 7-way cord
unplugged, use a voltmeter to measure the voltage between
the reefer ground stud and the reefer positive stud inside the
Select Controller (see V1 in Figure 13). It should read 13.8
volts or greater. If yes, and the light still is not solid green, call
customer service as the Select Controller or Control Module
may be defective. If no, proceed to step 2.
Step 2: With the reefer running and the stinger and 7-way cord
unplugged, use a voltmeter to measure the voltage between
the reefer engine block ground stud and the reefer starter
positive stud (see V2 in Figure 13). It should read 13.8 volts or
greater. If yes, repair or replace the wiring between the reefer
unit and the Select Controller. If no, check the reefer alternator
and the wiring between the reefer alternator and the reefer
starter. Repair or replace.
REFERENCE #8
Excessive Voltage Drop: Check wires and connections from
reefer to Select Controller, making sure wires are undamaged
and connections are clean and tight. Wires, connections, and
reefer charging system must be able to supply at least 10.5 volts
with a load of 20 amps.
REFERENCE #6
Rapid Flashing Orange LED:
Blown fuse on the reefer
circuit. Replace the fuse (see
Figure 12 for reefer fuse
location).
