Start, Neutral Engine Speed Control, Spray Pump and Spray Valve Relays
The start and neutral engine speed control relays are
used on both the Multi Pro 1200 and Multi Pro 1250. The
Multi Pro 1250 uses an additional three (3) relays for the
spray valve system. All relays are located under the op-
erator seat (Fig. 6).

During the 2003 model year, an additional relay was
added to both the Multi Pro 1200 and Multi Pro 1250.
This additional relay is used to energize the spray pump
clutch.
Two styles of relays have been used on Multi Pro spray-
ers. Later production machines (after serial number
1
240000400)
have a different terminal arrangement than
earlier machines (Fig. 7). Relay operation is identical re-
gardless of terminal layout.

NOTE: Prior to taking small resistance readings with a
digital multimeter, short the meter test leads together.
The meter will display a small resistance value (usually
0.5
ohms or less). This resistance is due to the internal
87
resistance of the meter and test leads. Subtract this val-
ue from from the measured value of the component you
are testing.

1.
Verify coil resistance between terminals 85 and 86
with a multimeter (ohms setting). Resistance should be
from 70 to 95 ohms.

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.

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