Ignition warning light
The warning light at the bottom of the revolution indicator dial glows red when the ignition is switched on and will
go out again when the engine is started and its speed is increased sufficiently for the dynamo to charge the battery.
Should the light glow at all engine speeds, the dynamo is not charging the battery.
Oil pressure gauge
The pressure of the oil should be between 30 and 80 lb./sq. in. (2·1 and 5·6 kg./cm. 2
)
under normal running con-
ditions. Approximately 10 lb./sq. in. (·7 kg./cm. 2 ) should be shown when the engine is idling.
Water temperature gauge
The temperature of the cooling water leaving the cylinder head is indicated by this gauge and should be approxi-
mately 160° F. (7lo C.) when the engine is running normally.
