Testing (cont).
(c)
Testing Starter or Glow Plug Relay.
NOTE
Testing is identical for either relay.
1.
Connect terminal "D" to
positive of 12-volt DC power
supply or battery.
2.
Prepare multimeter to read DC
voltage per instructions
supplied with multimeter.
3.
Check voltage at terminal "A"
with multimeter. Voltage
should be zero. If voltage is
present, replace relay.
4.
Connect terminal "C" to
positive of 12-volt DC power
supply or battery
5.
Check voltage at terminal "C"
with multimeter. Voltage
should read 12 volts DC. If
voltage is not 12 volts, replace
relay.

Installation.
(a)
Install plate (21) on engine housing. Secure plate with four screws (20), washers (19)
and nuts (18).
(b)
Install glow plug resistor (17) in position on plate and secure resistor with two screws
(16), washers (15) and screws (14).
(c)
Place relay (13) on plate (21) and secure with two screws (12), washers (11) and nuts
(10).
(d)
Install two relays (9) on plate (21) and secure with four screws (8), washers (7) and
nuts (6).
(e)
Connect engine wires to relays and glow plug resistor. Connect harness wires (1) to
relays (9 and 13) and glow plug resistor (17). Refer to next page for wiring diagram of
relay panel.
(f)
Refer to para. 4-22 and connect cables to battery.
