6.1 To Check KSM Internal Circuit
1. If the wiring and harnesses are in good order, continue troubleshooting by unplugging
the Deutsch connector on the end-faceplate of the KSM, providing access to the pin
terminals on the KSM connector. Refer Figure 5, Figure 6, and Figure 7.
2. With the circuit breaker reset, use a voltmeter to check voltage at Pin #1 of the
Deutsch four-pin connector and the KSM negative (–) ground power stud terminal. If
voltage is present, the circuit is good. The voltage reading is the actual KAPower
module voltage, and should be at least 12-volts for the 24-volt models and 6-volts for
the 12-volt models in order to activate the contactor.
3. Jump pins 1 and 2 on the four-pin connector, the contactor should activate and make
a “clunk” sound. If not, contact KBI for assistance.
4. If experiencing problems check the integrity of the vehicle or vessel side of the wiring
harness for issues such as shorts, corrosion, chafing, or bad connections and
components.
5. Check the circuit breaker and contactor relay connections within the KSM module. In
order to service or replace any of these components, remove the cover of the KSM
enclosure, with the assistance of KBI.
6. The PLC Module is a sealed unit. It cannot be serviced. If additional troubleshooting
is required, contact KBI.
