Re: Stevens’ Tester

[jerry-ahrens]

The Stevens in the above pic is a very versatile machine. It performs low and high Ohm’s [resistance] tests, along with a coil power test and a surface leakage test that checks for hairline cracks in the coil. The coil can be load tested with the correct amount of amperage supplied to the primary circuit, while watching to see if spark is produced thru the window on the machines control panel. It also does capacitance, resistance and a functional test [leakage test]for condensers. Another cool thing is the breaker points conditioner function, that sends a low amount of current thru the points while manually opening and closing them. This performs a cleaning of sorts on the contacts. You can also do a continuity test to see if the points are actually ”clean” enough to function. The meter must be in the Green area, to the far right of full scale while testing them for continuity. [using the top scale]
