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.
Starter No-Load Test
Make connections as shown in illustration (also connect a tachometer to starter). Operate starter motor and note voltage reading and tachometer reading. Disconnect starter from bakery. Turn load control knob until voltage reading is same as when starter is connected. Read the amperage drawn. If amperage reading is less than 65, starter has high electrical resistance. If starter RPM is less than 9000, worn bushings or bent armature shaft is indicated.
| Application | Specifications |
|---|---|
| Voltage | 12 volts |
| Amperage | 65-70 amps. |
| RPM Range | 9000-9250 |
