Lock Test
WARNING: This page is about a different variant/trim than selected.
- Using starter bench tester, connect test equipment and lock starter armature. Engage tester momentarily while measuring starter torque, current draw and voltage drop.
- Check specifications for minimum torque, voltage drop (minimum volts) and current draw (maximum amps). See STARTER SPECIFICATIONS .
- Low current draw and no torque during lock test may be caused by excessive resistance between brushes and commutator. Normal current draw but low torque speed may be caused by a shorted commutator and/or poor insulation. Repair or replace starter if performance is not as specified.
