FAULT 1): ENGINE STARTS,

opened, allowing the thermal switch to trip the pump supply after 30 seconds and
cause the engine to stop.

Observe the oil-pressure
gauge reading on the dashboard is above 5 p.s.i.
a) If pressure gauge is
reading correctly, proceed to D.2.
b) If no pressure is indicated check oil level
with the 'dip-stick' and refill if required. If oil is found to be present,
the engine oil pump should be checked.
D.2 Electrical Fault
CHECK the lead from the thermal switch to the oil-pressure switch, and the
corresponding terminals for possible 'earths'.
a) If no electrical fault is found, proceed to D.3.
b) If an electric fault is found, rectify as necessary.
D.3. Oil-pressure switch stuck closed.
RESET the manual switch
on the dashboard, after the required 15 seconds delay, and again attempt
