No-Load Test

WARNING: This page is about a different car, the 2016 Subaru Outback and 2016 Subaru Legacy. However, it is still accessible from the selected car via links, so may be relevant.

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

For no-load test, use the circuit shown in figure.

CAUTION:

Use a thick cable due to large current flowing through the cable.
- For B terminal and ground, it is recommended that the cross-section area of continuity part (shaded part) should be 20 mm 2 (0.00310 sq in) or more. For S terminal, 1.25 mm 2 (0.00194 sq in) or more.

- 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)

Using a vise, secure the starter.
CAUTION: Be careful not to deform or damage the starter.
Turn the switch ON, and check that the pinion protrudes rapidly into the specified position and rotates powerfully without noise.
Check the current and voltage after its rotation speed stabilizes.
