ABSTRACT:
A test point cap provides a visual indication of the voltage level of an alternating current in the conductor of a connector on which the cap is installed. The test point cap includes a bridge-type rectifier circuit which is capacitively coupled to the conductor through a test point terminal on the connector. The rectifier circuit charges a capacitor across which a neon lamp visible through a window in the end of the cap is connected, the rate at which the neon lamp flashes providing an indication of the voltage level on the conductor.
