26.3. Load Module (MPM)
String View > Diagnostics|Load Module
The Load Module diagnostic tests each load connection to the battery. This diagnostic tests
the connections, load cable fuses, load relays and load module, and can confirm actual load
current. Refer to the left side of the load connections drawing in the installation manual to
determine the load steps used for each configuration.
The Load Module also has a diagnostic that can confirm the direction of the current
transducer.
To test each load connection, open Load Module Diagnostics, select Load Module, then click
the Test Current tab on the dialog box. Identify the configuration that applies to the
installation. You can turn on each load step and confirm the current for that step. Each load
step must be from 17 to 23 amps when energized.
WARNING: When testing, do not leave the load module on for a long time. The load
module can overheat and damage hardware if not allowed to cool between tests. The load
module automatically turns off after 10 seconds.
