A relay is an electrically actuated switch.
1. Coil: Terminals 85 and 86 are connected to a coil.
Applying 12 volts to these terminals energizes the
coil turning it into an electromagnet.
2. Switch: Terminals 30, 87 and 87a are actually part
of a single pole, double throw (SPDT) switch. Ter-
minal 30 is the common lead. The switch is spring
loaded so that 30 and 87a are connected when the
coil is not energized. When the coil is energized, the
switch is “thrown” and 30 and 87 are connected (Fig.
0806).

The TX525 uses three relays to direct current ow to
different areas of the machine. The three relays are the
kill relay, the start relay and the glow plug relay.
The three relays are located inside the tower assembly
(Fig. 0805).
A. Interlock Relay C. Glow Plug Relay
