Cranking Amperage Draw

Mount starter on starter test stand. Make wiring connections as shown in illustration. Starter test stand should have a ring gear and a brake dynamometer. Ring gear should have minimum pinion/ring ratio of 1.0-10. If test stand is not equipped with correct pinion/ring ratio, follow manufacturers instructions in use of test stand. Test should be made with ambient temperature of 77°F. Observe amperage draw, voltage reading, and delivered torque while operating starter and check against specifications.
