Relays<br />
The <strong>Multi</strong> <strong>Pro</strong> <strong>5700</strong>–D uses three (3) relays that are attached<br />
to the electric panel under the operator seat. One<br />
of these relays is used to energize the cruise control coil.<br />
The other two relays are used in the spray system in<br />
conjunction with the master boom (foot) switch to turn<br />
the spray booms on and off.<br />
Testing<br />
NOTE: Prior to taking small resistance readings with a<br />
digital multimeter, short the meter test leads together.<br />
The meter will display a small resistance value (usually<br />
0.5 ohms or less). This resistance is due to the internal<br />
resistance of the meter and test leads. Subtract this value<br />
from from the measured value of the component you<br />
are testing.<br />
1. Verify coil resistance between terminals 85 and 86<br />
with a multimeter (ohms setting). Resistance should be<br />
from 70 to 90 ohms.<br />
2. Connect multimeter (ohms setting) leads to relay terminals<br />
30 and 87. Ground terminal 86 and apply +12<br />
VDC to terminal 85. The relay should make and break<br />
continuity between terminals 30 and 87 as +12 VDC is<br />
applied and removed from terminal 85.<br />

3. Disconnect voltage from terminal 85 and multimeter<br />
lead from terminal 87.<br />
4. Connect multimeter (ohms setting) leads to relay terminals<br />
30 and 87A. Apply +12 VDC to terminal 85. The<br />
relay should break and make continuity between terminals<br />
30 and 87A as +12 VDC is applied and removed<br />
from terminal 85.<br />
