two of the four relay connections are se-
cured with screws (Fig. 11). On machines with serial
numbers above 260000000, the glow relay is attached
to the wire harness with a four wire connector (Fig. 12).

Connect multimeter (ohms setting) leads to relay ter-
minals 30 and 87. Ground terminal 86 and apply +12
VDC to terminal 85. The relay should make and break
continuity between terminals 30 and 87 as +12 VDC is
applied and removed from terminal 85.
