CAUTION NOTE: This can only be done if the engine is equipped with automatic
starter disengagement. If the starter remains engaged while the start button is
depressed, after the engine has started, the starter may be damaged, in which case
this procedure cannot be used.
7. When the engine stops and the vehicle, or equipment is turned off, the KSM contactor
will open, keeping the fully charged KAPower module in reserve for the next engine-
starting event.
6.0 TROUBLESHOOTING AND MAINTENANCE
Maintenance of the KAPower module within the KSM enclosure is not required provided that
the operating conditions are proper, and that the requirements specified in this manual are
observed.
NOTE: During scheduled maintenance you can disconnect the 4-pin deutsch connector from
the KSM faceplate then start the engine using only the vehicle’s or vessel’s own key
switch or start button. Doing so will prevent the KSM from coming on-line, thereby
allowing the condition of the starting battery to be tested.
1. The LED located on the End-Faceplate of the KSM indicates the active condition of the KSM
module. See Figure 5 for location of this light. If the LED is not illuminated when expected
(see Section 4.3, Theory of Operation), ensure that all wiring and connections are in
accordance with the instructions within this manual. Check the integrity of the DPST switch,
and the power supply to the PLC (sourced from the engine ignition switched when ON) wiring
harness you created.
2. This LED is also an indicator for how the KSM is functioning. The LED is connected in
parallel with the contactor, and is also connected to an output on the PLC as shown in the
Figure 6 and Figure 7. The PLC monitors the capacitor voltage during, and after, the
recharge cycle. If the capacitor voltage drops below an acceptable level in the first 5 minutes
after the recharge, the LED will flash, indicating a fault. If at any time while the PLC is
powered up and the KSM Circuit Breaker trips or the capacitor voltage level drops below 6-
volts (on a 12-volt unit) or 12-volts (on a 24-volt unit), the LED will flash in a sequence that
indicates the fault, see Table 2.
