Reference is first given to the P.I. Electrical circuitry,
and a circuit diagram included. Intricate fault finding procedure on the
electrical side has been excluded, but a generalized
pattern is given if the fault is found to be an electrical one.
The pump is fed via the panel ammeter, a fuse and the
contacts of a 6RA relay. The relay winding if fed from the ignition switch via a
thermal switch, which is designed to
open in 30 seconds if the ignition is left on and the engine not started in that
time.
The thermal relay contacts will open should the engine oil
pressure be below 5 p.s.i. and a warning light is illuminated. The warning light
is built into a manually operated
resetting button mounted on the dashboard. This button should be pressed to
reset, approximately 15 seconds after tripping.
Manual over-riding of the
thermal relay is
possible by holding the button in the depressed position.
