Hold-In Coil Winding Resistance Test
The result of this test will determine the resistance of
the hold-in winding.
(1) Insert piece of paper between contact points to
serve as insulator (fig. 1F-16).
(2) Use ohmmeter to measure resistance between
terminal and starter frame.
Resistance should be between 2.0 and 3.5 ohms. If
resistance is not within specification, replace field wind
ing assembly.
Solenoid Contact Points Connection Test
The result of this test will determine the quality of the
solder joint at the contacts. Use an ohmmeter to meas
ure the resistance through solder joint (fig. 1F-17). If the
resistance is more than zero ohms, solder joint has ex
cessive resistance. Repair by heating joint with 600 watt
soldering iron.

Insulated Brush Connection Test
The result of 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 solder joint by touching probes to
brush and to copper bus bar (fig. 1F-18). If resistance is
more than zero ohms, solder joint has excessive resist
ance. Repair by heating joint with 600 watt soldering
iron.
Terminal-to-Brush Continuity Test
The result of this test will determine the condition of
all field winding solder joints.
