Abstract: Capacitor discharge ignition analyzer includes a pulse source operable to generate electrical signals related to the inputoutput signals of various capacitor discharge ignition systems including battery driven and alternator driven systems. The pulse source may include a relaxation oscillator and switching transistors to generate appropriate initial charging pulses and delayed triggering pulses. Individual load matching circuit are provided to match the load normally applied to the trigger circuit of breakerless ignition systems. An on-off indicator is connected to be driven from the matching circuits. The analyzer also includes an electronic circuit generating an output signal approximating that of the permanent magnet alternators for charging of alternator driven systems. The circuit also includes means to generate a trigger pulse a predetermined time after the charging pulse. The analyzer also includes a self-testing circuit, and may be powered from a conventional battery. A polarity sensitive circuit indicates proper and improper battery connections. The analyzer includes a converter for generating alternating polarity signals, with the circuit connected to provide individual signals matched to selected types of ignition systems. A selection switch means provides for selected connection between an input-output tap means on the analyzer and the ignition circuits. The output of the capacitor is analyzed by a spark gap with an outer enclosure having a small opening. This permits direct testing of the ignition system on the engine without any practical danger of generating explosions as a result of surrounding gas fumes. A separate meter is provided to permit static testing of the output of the voltage and resistance characteristics of the several circuits, with a special energy adaptor being provided to permit selected connection of the ignition capacitor outputs into the meter.

Abstract: CATHODIC PROTECTION MONITORING APPARATUS FOR MARINE PROPULSION DEVICES A cathodic protection system monitor is coupled to an impressed current cathodic protection circuit used for corrosion protection of a submerged marine drive. The cathodic protection circuit includes one or more anodes and a reference electrode mounted below the water line and connected to an automatic controller for supplying an anode current which is regulated in order to maintain a predetermined reference potential on the protected structure. A switch selectively connects a light emitting diode (LED) lamp or indicator to between controller current to operate the lamp and monitor the change in the cathodic protection current to defelct when adaquate power is available to the anode.

The cathodic protection circuit includes one or more anodes and a reference electrode mounted below the water line and connected to an automatic controller for supplying an anode current which is regulated in order to maintain a predetermined reference potential on the protected structure. A switch selectively connects a light emitting diode (LED) lamp or other light source between the controller output and ground so that the controller current may, when tested, be used to operate the light source in order to confirm that power is available to the anode.
