TEST PROCEDURE

1. Remove the weld wire from the drive rolls.

2. Disconnect the motor leads, 541 and 539, from the Control Board and clamp an amp probe around one of the leads.

NOTE: A DC ammeter may be connected in series with a motor lead if a current probe is not available.

3. Connnect a 12 VDC supply to the motor leads - Positive to lead 541 and Negative to lead 539.

The drive rolls should turn and run smoothly and the motor current should be less than 1amp. If so the feed head is OK.

If the drive rolls do not turn, and the ammeter shows no current, check the brushes for excessive wear. Insure that they move freely in the brush holders and are contacting the armature.

LN-23P

If drive rolls do not turn but the ammeter indicates current flow. remove the motor from the gearbox and repeat the test.

If the motor still does not run it is defective. If it runs properly there is probably something wrong in the gearbox.

If the drive rolls turn but not smoothly check the motor and brushes as indicated. If OK replace the gearbox.
