Glow Relay (Gr3200-D) - Toro Greensmaster 3200 Service Manual

Glow Plug and Lower Reels Timer (GR 3200–D)
This is a solid state timer. Upon the application of power,
the load is energized and the time delay is started. After
6 seconds the load is de–energized.
1. Connect voltmeter across test load and test load to
timer. Connect 12VDC source to timer and load. Make
sure to observe polarity. After 6 seconds, there should
be no voltage across the load.
2. Disconnect timer from 12VDC source and test load.

1. Verify coil resistance between terminals 86 and 85
with a multimeter (ohms setting). Resistance should be
from 41 to 51 ohms.
2. Connect multimeter (ohms setting) leads to relay
terminals 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 ap-
plied and removed from terminal 85.
3. Disconnect voltage from and multimeter leads from
relay terminals.
