Abstract

PURPOSE: To obtain an ignition time indicator capable of monitoring the change of timing, the eccentricity and wearing of a cam part, and the damage by a fire of a point etc., by means of monitoring the rotation angle (a cam angle) of a distributor cam when the point is in closing.
CONSTITUTION: Generally speaking, if the cam angle may become enlarged, the temp. becomes to be raised by means of generating heat by coils and the current quantity is reduced by means of enlarging the resistance, and owing to these, a full secondary voltage is difficut to be generated, and the insulating materials in a coil are deteriorated. Then, as a monitoring device of a cam angle, this indicator is constituted as a device that the voltage of the circuit is made at a constant in a point A by the action of a resistance 32 and a Zener diode 34 by means of closing a bipolar switch 30,31, and is supplied to a resistance 36 of a meter center setting circuit, and to a volume 38 for the purpose of center setting the pointer of a meter 52, and the volume 38 is connected to an ignition coil 3 via a diode 50.
