For all the small engine mechanics and DIYers, this is an invaluable reference chart for diagnosing electrical issues. The guide clearly illustrates how to perform two essential tests on an engine's charging system: the AC Volts Test and the DC Amps Test.

AC Volts Test: This part of the chart shows how to check the output of the engine's alternator (stator). It details:

Meter Settings: Set your multimeter to AC Volts.

Connections: How to connect the tester leads to various types of output connectors from the stator.

Conditions: The engine must be running at a specified speed, typically 3,600 rpm.

Readings: The minimum AC voltage you should expect, which confirms if the stator itself is generating power correctly.

DC Amps Test: This section demonstrates how to test the battery charging circuit. It details:

Meter Settings: Set your multimeter to DC Amps.

Connections: How to connect the meter in-line between the engine's charging wire and the battery.

Conditions: The test is performed at a specific RPM (e.g., 3,600 or 2,800 rpm).

Readings: The minimum DC amperage the system should be putting out to charge the battery effectively.

This chart is a fantastic diagnostic tool for quickly determining whether an issue lies with the stator, the regulator/rectifier, or wiring.
