STEEL HOPPER SPREADERS – RELAY KIT INSTALLATION – GAS
RELAY KIT INSTALLATION INSTRUCTIONS
NOTE: The Relay Kit (PN 48627) is used to
prevent voltage spikes caused by the gas
hopper control.
1. Trim the red wire from the control as needed
and crimp on the supplied insulated terminal.
Connect the wire to relay terminal 87.
2. Connect the supplied green wire to relay
terminal 85. This wire should be connected to
vehicle ground.
3. Connect the supplied red jumper wires to relay
terminals 30 and 86.
4. The red wire connected to relay terminal 30
should be connected to an under-dash
12V source (battery voltage) capable of
supplying 15A.
If needed, extend the wire to reach the
POSITIVE (+) terminal of the battery. The
extended wire will need to be protected by a
20A in-line fuse (not supplied).
5. The red wire connected to relay terminal 86
should be connected to a switched 12V source
(+12V when vehicle ignition is ON, 0V when
vehicle ignition is OFF).
NOTE: When connecting to a fused vehicle
switched 12V source, always connect to the
"load" side (protected side) of the fuse (i.e., so
there will be no power if the fuse opens).

CAUTION
Connect green wire from ground to relay
terminal 85. Reversing this connection will
damage the internal relay diode, causing
the relay to be inoperable.
