No-Load Test

The following test must be performed within 3 to 5 seconds to avoid burning out the coil.

Fig. 4 No-load performance test connection locations:

1. While keeping starter immobile, connect ammeter in series as shown in Fig. 4.
2. Ensure starter rotates smoothly with pinion moving out. With battery voltage 11.5V, ammeter should read 90A or less on ES 250, ES 300 and SC 300 models and 120A or less on LS 400 and SC 400 models.
