PROCEDURE

1.Turn engine off.

2.Make sure that the battery is fully charged and in good condition, and the battery connections are clean and tight.

The Engine and generator should be at normal operat- ing temperature for this test. If the machine is cold, the voltage readings may be slightly higher than specified.

3.Open either, or both of the doors on the control panel end of the SAE-400 machine.

WARNING: Secure the doors in the open position using the door restraint system. If the machine does not have a door restraint system, remove the doors or securely restrain them to prevent them from falling closed.

4.Remove the covers from the exciter/auxiliary power alternator by removing the screws securing it. See Figure F.6.
