Illustrated here is the Stevens Ignition Analyzer or testing unit - a dial reading instrument designed to operate off a 110-115 volt A.C. plug-in. No battery or other source of electrical energy is required during test procedure.

It's a dial reading unit provided with five (5) stations to simplify evaluating -

1. Condenser Capacity
2. Current leakage
3. Coil Test
4. Breaker point contact
5. Series resistance

A probing lead is included to check for possible seepage through the coil tube.

Each test or check is accomplished by directing the switch arm to position indicating desired test or check at the moment. In any event, where the dial needle falls in the "green" area of the particular quadrant selected, that check meets specification set up for the test, failure is revealed when the needle falls in the "red" area.
