Lawnmower Charging System Troubleshooting

The video tutorial addresses a lawnmower battery issue where the system isn't charging. It explains the setup of a Briggs and Stratton engine, including the voltage regulator and voltmeter connections. The tutorial guides viewers through checking battery connections, testing AC voltage output from the flywheel, and analyzing different voltage regulators. It concludes with final checks and a bonus segment testing alternator output with an amp meter.

What is the primary issue discussed in the video regarding the lawnmower?

• The lawnmower engine is not starting.

• The lawnmower battery is going dead.

• The lawnmower blades are dull.

• The lawnmower is leaking oil.

What component converts AC voltage to DC voltage in the lawnmower's charging system?

• The battery

• The voltage regulator

• The alternator

• The flywheel

What should you check if there is no battery voltage on the wire going to the battery?

• The spark plug

• The engine oil level

• The connection from the voltage regulator

• The fuel level

What voltage reading indicates that the flywheel is generating sufficient AC voltage?

• 26 volts

• 15 volts

• 10 volts

• 5 volts

Why might a good voltage regulator show only four-tenths of a volt?

• The battery is fully charged.

• The regulator is malfunctioning.

• The engine is not running.

• The voltmeter is set incorrectly.

What is the purpose of using a jumper in the testing process?

• To start the engine

• To bypass the voltage regulator

• To read the actual voltage with the battery in line

• To connect the voltmeter to the battery

What is the expected maximum amperage output of the alternator?

• 20 amps

• 12 amps

• 10 amps

• 16 amps

What could cause a voltage drop at the other end of the wire?

• A faulty battery

• A short circuit

• High resistance in the wire

• A broken flywheel

What should be checked if the stator output is good but the battery is not charging?

• The fuel level

• The engine oil level

• The voltage regulator

• The spark plug

What is the main conclusion of the video regarding the charging issue?

• The voltage regulator is likely faulty.

• The flywheel needs adjustment.

• The battery needs replacement.

• The engine needs tuning.
