Impreza WRX STI F4-2.5L Turbo (2008)
1. No-load test
Adjust the variable resistance with the switch on until the voltage is 11 V, and read the value displayed by the ammeter to measure starter
speed. Compare these values with the standard.
No-load test (standard):
Voltage/Current - Max. 11 V/90 A or less
Rotating speed - 2,860 rpm or more
2. Load test
Apply the specified braking torque to starter. The condition is normal if the current draw and starter speed are within standard.
Load test (standard):
Voltage/Load - 8 V/9.3 N.m (0.9 kgf.m, 6.9 ft.lb)
Current/Speed: 280 A/860 rpm or more
3. Lock test
With the starter stalled, or not rotating, measure the torque developed and current draw when the voltage is adjusted to standard voltage.
Lock test (standard):
Voltage/Current - 4 V/515 A or less
Torque - 16 N.m (1.6 kgf.m, 11.8 ft.lb)
