To install the regulator:
1.
Mount the regulator in a dry, well-ventilated location, well
away from hoses and exhaust manifolds which may cause
damage to the regulator or wiring. Avoid areas of heat
and/or high vibration.
2.
Attach the Ford-type harness plug to the regulator (see
Figure 1
).
3.
The
RED
wire (in the harness) powers the regulator. Attach
at the positive output terminal at the alternator. If an isola-
tor is used, this wire must be located on the battery side of
the isolator. On a 24V system, this wire can carry 8 amps
and must be protected by a 10-amp fuse. A fuse is includ-
ed with the wiring harness.
3.
The
BROWN
(ignition) wire activates the regulator when
+24VDC is applied to the system. Attach the BROWN wire
to a sw24VDC source. The auxiliary side of the
ignition switch, or an independent (ungrounded) oil pres-
sure switch are both acceptable connection points. A tog-
gle switch may be added to this circuit to shut down
the alternator load in cases where maximum propul-
sion is needed.
5.
The
BLACK
(ground) wire in the harness attaches to
the System Ground Terminal. The BLACK wire
attaches to preferred ground terminal on the alterna-
tor. A (user supplied) ground strap between the alter-
nator and the preferred ground at the engine is also
strongly recommended.
6.
Plug duplex connector with
BLUE
(field) and
ORANGE
(stator) wires into rear of alternator.
7.
An AC tap wire for the tachometer can be utilized by
splicing into the ORANGE stator wire with a wire
connecting to the AC tap terminal at the tachometer.
