This blog, in addition to the usual maintenance details for classic mini cars, an attempt is made to explain the "whys" and "wherefores" of the various jobs.

The Instruments and Controls

If the driving belt appears to be sound and correctly tensioned, failure of the lamp to be extinguished indicates a fault in the charging circuit, either in the dynamo, control box or wiring, which should be investigated at the earliest possible opportunity by a specialist. The reserve of current stored in the battery can be exhausted comparatively quickly, particularly when driving at night even if one forgoes the luxury of keeping the heater or radio in operation.

If the light does not glow when the ignition is first switched on, it is obviously essential to check the bulb in the warning lamp and renew it if necessary, or to trace and put right the fault in the circuit.
