3. In the water or on a Dynometer, start the engine and bring the RPM up to approximately 3500 in gear.
4. Turn on the load bank switches to increase the battery load to equal at least 20 Amps.
5. Check the ammeter, you should see approximately 16 Amps. If the amperage is too low, replace the battery and retest. If is still too
low, check the stator resistance and DVA.
6. Increase RPM to 5500 RPM in gear.
