PROCEDURE
1.Remove input power to wire feed unit.
2.Using the 3/8 in. nut driver, remove the cover from the wire feeder.
3.Locate the two quick connectors in the two motor armature leads. Refer to Figure F.3. Do NOT disconnect the leads.
4.Apply the correct input power (from the POWER FEED® 25M control cable) to the wire feeder. Activate the gun trigger and with the motor running check at the quick connectors [#550 White (+) to #551 / Black
5.If the correct voltages are NOT present at the motor leads, check the associated leads between the motor and plug J83 on the feedhead board. If the leads are OK, the feedhead board may be faulty.
6.If the correct voltages are present at motor armature leads and the motor does not run and vary speed with changes in armature voltage, the motor or gear box may be faulty. See Gear Box and Drive Motor Removal and Replacement.
7.Install the wire feeder cover using the 3/8 in. nut driver.
