STARTING SYSTEM - MOTORCRAFT (6-Cyl. Engine)
Insulated Brush-Connection Test
This test will determine the quality of the solder
joint between the insulated brush braided wire
and the field windings. Use an ohmmeter to test
the resistance through the solder joint by
touching the test probes to the brush (4) and to
the copper bus bar (5).
If the resistance is more than zero ohms,
joint has excessive resistance.
the
Repair by resoldering the joint with a 600 watt
soldering iron.

Field Winding-Terminal to Brush
Continuity Test
This test will determine the condition of all the
field winding solder joints.
Insert a piece of paper between the contact
points to insulate them (6).
Touch the ohmmeter test probes to the field
winding terminal (7) and to the insulated brush
(8).
If the resistance is greater than zero ohms,
inspect all the solder joints to determine which
have excessive resistance. Repair the faulty
joint(s) by resoldering with a 600 watt soldering
iron.
