Testing.
NOTE
Multimeter should read less than
3 ohms in Step (2). If multimeter
reads above the specified limit,
field coil is open and must be
replaced.
(1)
Check for open field coil. Set multimeter to
x1 range and zero meter. Touch one
multimeter test lead to F+ (1) and other test
lead to F- (2) and measure resistance.

Multimeter should read infinity in
Step (3). If multimeter reads less
than infinity, field coil is
