Starter Load Test

Make connections as shown in Fig 1. Crank engine with ignition coil secondary wire grounded and note voltage on tester. Stop cranking engine and turn load control knob until voltage reading is exactly the same as it was during engine cranking. Read current draw on ammeter scale. If not within specifications, starter is defective and must be overhauled.
