Problem
Possible Cause and Solution
High engine temperature shutdown - • Incorrect dip-switch settings. All dip-switches at the rear
High engine temperature light, illuminated: of the module, bottom right hand side must be on the
‘ OFF ’ position. Please refer to image 70.
High engine temperature shutdown - • Is the sea water inlet sea cock diameter correct? please
High engine temperature light, illuminated: refer to the chart within ‘Sea Water Inlet for Heat Exchanger
Cooled Engines’.
• Check that the sea cock is fully opened and that the sea
water intake and/or filter are not blocked, causing
insufficient sea water flow.
• Check the the seawater pump impeller is not worn or
damaged, replace should it be required. If the impeller has
a vane missing it will be lodged either in the pipe leading
to the heat exchanger or within it, this must be located and
removed*.
• The tube stack within the heat exchanger may be
blocked*, remove the tube stack, clean and re-assemble,
always using anew pair of replacement O ring seals.
Please refer to ‘Heat Exchanger Tube Stack & Wasting
Zinc Anode’.
The generating set DC battery charging alternator fails • The ignition connection on the DC alternator (small brown
to excite - Battery charge light illuminated: wire from the DC alternator to the 11 way connection plug
terminal 9) is not connecting to the module socket terminal
7. Inspect the connections and check continuity of this wire.
• The charge fail connection on the DC alternator (small
brown/black wire from the DC alternator to the 11 way
connection plug terminal 7) not connecting to module
socket terminal 8. Inspect the connections and check
continuity of this wire.
