ABSTRACT:
Operating parameters of an engine, such as coolant temperature, oil pressure, air filter flow and the like, are continuously monitored by an electrical circuit responsive to sensor switches. The circuit distinguishes between conditions which require immediate correction, such as low oil pressure for example, and conditions such as reduced porosity of the air filter which need not necessarily be corrected immediately but which should be attended to at the end of the current vehicle operation. The two types of conditions are signalled to the operator by different means and the signalling means for noncritical conditions remains latched on after the engine has been shut down to alert maintenance personnel to the need for corrections. Means are provided for selectively testing the system, for discriminating against nonsignificant, brief, actuations of a sensor switch and for selectively turning off signalling means which have been latched on.
