of the firewall in the engine compartment.
The fuse blocks hold fuses that protect
individual circuits in the tractor's
electrical
system.
The fuse blocks hold a total of five fuses.
The fuse blocks contain the following fuses:

6) RELAY FOR SAFETY START
Description and Location
Relay is used to automatically complete
(close) a circuit.
A relay contains two parts of a circuit. One
part, the control circuit, uses current to
energize a coil. The other part, the function
circuit, is a switch. When energized, the coil
of a relay becomes an electromagnet opening
or closing a single circuit.
The safety relay utilizes single-pole,
single-throw switch (SPST).
Relay employs a diode to direct current in
the control circuit.
The function circuit, 2, is normally open
when no current is being supplied to the coil,
1. If a circuit with an SPST relay is
energized with current on the tractor, the
switch becomes closed and the circuit is
completed. The relay is then said to be
latched.
The relays coil is energized when the range
safety switch, PTO safety switch and mid
PTO switch (if installed) are all closed.
