Abstract
Monitoring apparatus which comprises a plurality of monitoring circuits arranged to indicate the malfunctioning of various components and systems for a motor vehicle. These warning circuits include a generator warning circuit and an oil-pressure warning circuit. To prevent activation of the generator and oil-pressure warning circuits when the vehicle ignition is turned on but the vehicle engine is not running, a respective switching device is inserted in each circuit. The switching device controlling activation of the generator warning circuit is arranged to activate the latter only when the engine oil pressure reaches a level indicating that the engine is running. The switching device controlling activation of the oil-pressure warning circuit is arranged to activate the latter only during operation of the generator. With this arrangement when the vehicle ignition is initially turned on the warning lights of the generator and oil pressure warning circuits will not be illuminated as generally happens. Preferably, a green indicator light is provided which is arranged to light up when the apparatus detects no faults.
