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.
Performance Tests
Mount starter in test stand and perform running test, no load test and stall (lock) test. Starter should develop 31.7-35.1 INCH lbs. (3.6-4.0 N.m) torque while drawing 280 amps and 9.5 volts at 1500-1700 RPM. At 12 volts and 28 amps under no load conditions, armature speed should be 4700-5700 RPM. Stall torque test should produce 143-159 INCH lbs. (16.1 5-18.05 N.m) torque at 12 volts and 28 or less amps.
