No-Load Test

WARNING: This page is about a different variant/trim than selected.

The starter should be placed through a no-load test whenever it has been overhauled.

CAUTION:
  • Use a thick cable due to large current flowing through the cable.
    • It is recommended that the cross-section area of continuity part (shaded part) should be 20 mm2 (0.00310 sq in) or more for terminal B and ground, and 1.25 mm2 (0.00194 sq in) or more for terminal S.

    • It is possible to use a booster cable instead of wiring.
  • Be careful not to burn yourself and cause a fire due to heat.
  • Perform the no-load test in a short period of time. (Within 3 to 5 seconds)
NOTE: For no-load test, use the circuit shown in figure.
