8.2 1975 to 1978
Note: 1975-1978 could have either Motorcraft or Delco systems installed.
8.2.1 Motorcraft Alternator (2 configurations). See Figure 8.3.
Note: Your Alternator may not appear exactly as represented in
Figure 8.5. The circuits are wired the same way, though.
Figure 8.3 Motorcraft Alternator (2 configurations)
A. Connect the provided 6 gauge red wire to the Alternator Output lug
(Bat). Connect ENGINE SECTION wire #714 (wht) to the Voltage
Regulator (l) terminal.
B.
Connect wire #795 (red) to the Voltage Regulator A terminal.
C. Connect a 14-gauge wire from the Voltage Regulator S terminal to the S
terminal of Alternator. Connect a 14-gauge wire from the Voltage
Regulator F terminal to the Alternator Field (F) terminal.
D. Connect the Alternator Ground lug and the Voltage Regulator to chassis
ground.
E. An alternate (and less-used) method is to omit the Alternator Stator (S)
wire, install a 14-gauge jumper across Voltage Regulator terminals A and
S, and connect wire #714 to either the A or S terminal on the Voltage
Regulator. The FIELD wire and the output wire from the alternator are
connected as above. The Voltage Regulator Ignition (l) terminal is not
connected and wire #795 (red) will not be used. Install ground wires as
in Section 8.2.1, Step D. This alternate configuration is illustrated in
dashed lines in Figure 8.5.
