Abstract
A detection device having pushbutton operation which after a short predetermined period of time indicates by means of lights whether both oil and lubricant levels are adequate or if not which is not satisfactory. If lubricant is indicated as being low, then means are provided to indicate the required amount of lubricant. The device is coupled with circuitry so as to quickly activate a thermistor within the lubricant reservoir for accurate detection at that point and may be coupled with engine deactivation means to preclude engine operation in the event that the device is not activated or in the event that either of the coolant or lubricant levels are inadequate.
Claims7
A detection device for sensing lubricant and coolant levels in a motor driven vehicle, comprising
- a multiplicity of lubricant level probes;
- a coolant level probe;
- circuitry communicating with said probes;
- a normally off pressure switch activating said circuitry;
- a first light emitting diode communicator with said circuitry to light if all of said probes detect the presence of the appropriate fluid;
- and
- other light emitting diodes associated with said coolant and lubricant level probes and said circuitry to light in the absence of appropriate fluid instead of said light emitting diode.
