Abstract : Describes a transistorized engine chip detection system including a milliammeter to give a visual indication of chip buildup and a full light to operate at a critical preset level. Utilizing a voltage divider network, a decrease in resistance in the chip detector will cause an increase in current flow, and subsequent lighting of a warning light. A short circuit or large chip would turn light on and give full scale meter reading; broken or unplugged harness turns light on and gives zero meter reading. (Author)
