Problem
Possible Cause and Solution
The generating set engine doe not start but turns over • Starter battery is discharged, charge or replace, check that
very slowly and or stops: the DC alternator belt is correctly tensioned.
• Starter motor ingressed by moisture/water, remove and
clean or replace.
• Water in cylinders causing hydraulic look – Incorrect Heat
Exchanger installation or continuous cranking with the sea
cock open. Check lube oil for signs of water, do not attempt
to start engine. Get the engine checked by a dealer or
service agent.
The generating set engine pre heat is not operating: • Time the duration of the programmed pre heat, engine
not cranking period is correct > 6 seconds maximum.
• Check connections on the engine harness to preheat relay
and on to engine heaters (red wire).
• Check the pre heat relay. Best practice is to inhibit the
generating set engine from starting by temporarily
removing the red/white connection from the starter
solenoid. Measure the voltage on heaters to ground with a
voltmeter set to read DC. If it reads as being close to 12v
the relay is functioning correctly. If no voltage is measured,
temporarily swap the start relay with the heat relay.
Measure the voltage again on heaters. If voltage is now
measured, replace the original faulty heat relay with a
new relay.
