How to Perform an Alternator Test on a Briggs and Stratton Engine
- Step 1: Connect a charging system voltage multi-tester to the engine For a Briggs and Stratton engine look beneath the blower housing above the starter on your engine for the connector that is attached to the stator (yellow wires).
- Step 2: Start the engine Start the engine of the piece of equipment that you’re testing.
- Step 3: Turn off the engine
How do you test an alternator on a lawn mower? For the easiest alternator test, simply turn on the headlights to your lawn mower or outdoor power equipment. Then, turn off the engine. If the lights dim, the alternator works. If not, it doesn’t. If this isn’t an option, follow these steps on how to test alternators. Connect multi-tester to your engine based on your alternator type.
Where are the alternator wires on a Briggs & Stratton engine? These wires extend beneath the blower housing and are connected to the stator. For Briggs & Stratton engines, you can match up the wires and alternator’s configuration with your Alternator Identification Chart. Once you find a match, find the AC/DC setting in the upper right hand corner (outlined here in red).
How do you connect a multi-tester to an alternator? Connect multi-tester to your engine based on your alternator type. You can determine this by the color of the wires – either AC volts or DC amps. These wires extend beneath the blower housing and are connected to the stator.
How do you test a carbon pile alternator? Zero out the ammeter (connect as above and perform the test with the vehicle off). Start the vehicle and hold the engine at around 1,500 rpm. With the engine held, the carbon pile can simulate an electrical load. Alternator output should increase, and the ammeter reading should register close to the alternator amp rating.

How do I know if my Briggs & Stratton ignition starter is working? A spark should be visible in the tester. If no spark appears, check for broken wires, shorts, grounds or a defective stop switch. Once you have confirmed that the stop switch is working, reconnect the spark plug lead. If your ignition start or push button start needs replacing, consult a Briggs & Stratton dealer near you.
What are the safety warnings on my Briggs & Stratton engine? WARNING: Always read the engine and equipment manual (s) before starting, operating, or servicing your engine or equipment to avoid personal injury or property damage. See an authorized dealer or contact Briggs & Stratton if you are unsure of any procedure or have additional questions. Find all Engine Safety Warnings
How do I improve the reliability of my Briggs & Stratton engine? You can improve its reliability on a single-cylinder Briggs & Stratton engine equipped with breaker points and a two-leg armature by installing a solid-state ignition conversion kit (service part number 394970) that bypasses the points (conversion kit will not work with a three-legged ignition armature).

How do you test an alternator on a small engine? Alternator Test on Your Small Engine. Alternators power the small engine while it is running, keeping the battery charged by circulating power back through the system. For the easiest alternator test, simply turn on the headlights to your lawn mower or outdoor power equipment. Then, turn off the engine. If the lights dim, the alternator works.
How do I know if my lawn mower alternator is bad? Start the mower’s engine and allow it to run at full throttle for several minutes. Check the readings of the multimeter to ensure they are as high or higher than the amps indicated in your user’s manual or on the mower’s product label. A considerably lower reading indicates a problem with the alternator.
Does a small engine include a battery and alternator? Note: If you use a key to start your lawn mower, snow blower or outdoor power equipment, the small engine includes an electrical charging system with a battery and alternator.
