Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Alternator Output
Connect an ammeter in charging line at alternator "BAT" terminal (disconnect lead and connect ammeter between lead and terminal), connect voltmeter between this "BAT" terminal and ground. Disconnect alternator field lead at "F" terminal and connect field directly to battery by installing jumper wire between alternator "F" and "BAT" terminals. Start engine and slowly increase speed using care to prevent excessively high voltage. Check alternator output at 1500-2500 RPM. Output should be within 10 amperes of rated output. See Specifications.
