Two styles of glow relays have been used on the
Groundsmaster 3500--D. On machines with serial num-
bers below 240000000, two of the four relay connec-
tionsaresecuredwithscrews(Fig.7).Onmachineswith
serial numbers above 240000000, the glow relay is at-
tached to the wire harness with a four wire connector
(Fig. 8).
