1. A recorded voice warning system for providing safety alerts and personal messages to a device in a vehicle comprising: (a) a modified reversible cassette tape recorder having a dual record and playback head assembly and an endless-loop magnetic tape that incorporates a set of prerecorded safety alert messages, (b) a set of fault detecting sensors where each of said sensors provides an electrical signal when a change corresponding to a specific safety alert occurs and where each of said sensors is optimally located in a section of said vehicle that best provides the chanve, (c) a set of electronic circuits where said circuits have the means to accept and process the signals from said respective sensors and to then turn on and off said recorder playback mode at a precise time to allow the playback of a selected ssfety alert message corresponding to the specific fault detected by the respective said sensor, (d) means to annunciate each of said safety alert messages to the driver in said vehicle, and (e) a timed message circuit that allows a timed personalized message to be recorded on said recorder where said circuit comprises: A a digital clock that is programmed to provide an output signal at the expiration of any preselected time within a one-year period, B a flip-flop that is set by the output signal from said clock, C a two-input AND gate that is enabled when a signal from said flip-flip is received together with a signal from a speed timer that produces the second enabling signal when the drive exceeds a speed of 20 mph, D a two-input OR gate that is enabled by the output signal from said AND gate, and E an output timer that when triggered by the signal from the enabled OR gate produces an output signal F for a period of time that is needed by said endless loop tape to complete one revolution where said F signal simultaneously turns on said tape motor and closes the respective switch on said multiplexer to allow the personal message to be annunicated over a speaker located in said tape recorder.
