Field Coils
Check field coils for open circuit using a circuit tester. Connect one test prod to field coil lead and the other prod to soldered portion of brush lead. If meter does not register, field coil is open. Repair or replace as necessary. Check field for ground by connecting one test prod to field coil and other lead to starter housing. If meter registers, coil is grounded. Remove field coil and repair or replace as necessary.
