Step 4
•
Having mounted both contactors, disconnect the load wires from the Main / Engine
battery.
Note:
For Engine Start Protect systems, the starter & alternator are usually connect
directly to the battery positive terminal, often through a shared cable. Both should be left
connected directly to the Main / Starter battery, but all other connections should be made
to the ““Load Positive” stud.
•
Connect one end of the power cable “Power Cable A” see Figure 2 (This cable is not
normally supplied) to the primary contactor “Battery Positive” stud.
•
Connect the other end of power cable “Power Cable A” to the Main / Engine battery
positive.
•
The control module should now be powered; press and hold in the “Engine Battery On
/ Off” switch for 3 seconds to ensure that the primary contactor is open (the switch
LED should flash whilst the switch is pressed).
Note:
Whenever the control module has powered applied, calibration data is read from
memory. Once this is completed; both switch indicator LEDs flash twice to indicate a
successful read. For other flash patterns, see
Error! Reference source not found.

Step 5
•
Connect the engine loads that were disconnected in the previous step to the primary
contactor “Load Positive” stud.
Step 6
•
Connect one end of power cable “Power Cable B” see Figure 2 (not normally supplied)
to the secondary contactor “Load Positive” stud.
•
Connect the other end of power cable “Power Cable B” see Figure 2 to the Main /
Engine battery positive.
Note:
If all of the above steps have been carried out correctly and the “Battery Link”
switch LED is “Off”, then the secondary contactors “Battery Positive” stud should not be
Live. If however, the “Battery Link” switch LED is “On” then the “Battery Positive” stud will
be live therefore take care in the following step.
•
Connect one end of the “Power Cable C” see Figure 2 (not normally supplied) to the
secondary contactor “Battery Positive” stud ensuring that the other end is insulated.
Note:
If the “Battery Link” switch LED is “On” the next step is likely to cause a spark, so
ensure that any battery gasses are dispersed before making this connection.
•
Connect the other end of “Power Cable C” to the auxiliary battery positive.
