Installation
Instructions for the F7078 One Wire Voltage Regulator
You must furnish a
1965 Ford Falcon Alternator. We only provide the voltage regulator that
mounts on the back of it.
 Disconnect
battery.
- VERY IMPORTANT: Add a 10/32" nut on each ground stud on
the back of the alternator. These will act as stand offs and prevent
the wires from getting pinched against the case and shorting out.
- Connect the black wire to one
of the ground studs while mounting the regulator and secure assembly with 2
more 10/32" nuts.
- Connect the red wire to the
large red insulated terminal labeled " bat ".
- Connect the green wire to the
terminal labeled " fld ".
- Connect the yellow wire to the
terminal labeled " sta ".
- Install alternator on the engine.
- After installing the alternator and
one wire voltage regulator, there is only one wire involved to make
the alternator charge the battery. One 10 gauge wire from the back
of the alternator - BAT terminal to the positive side of the starter
relay. That is it. The alternator will now charge.
- If you want to use the in-dash warning
light, it must be connected to the Orange wire on the
new regulator.
- Now the problem is what to do with the
wires on the old generator? Since you don't use the
wires, you may remove them or just tape them back. However, if you
want to hook up the
warning light, you might want to use one of the existing wires to do
that.
We have found that using the white wire from the field terminal of
the old generator, which is
now disconnected can be connected to the Orange wire of the new
regulator. Now all we have to do is find the other end of this white
wire and the wire that leads to the warning light,
connect those two ends together and the warning light should
function.
The other end of the white wire is connected to the FIELD terminal
of the original voltage
regulator. The warning light wire is a small yellow/black wire
connected to the ARMATURE
terminal of the old voltage regulator. Disconnect both of these
wires from the old voltage regulator and splice the ends together.
The warning light should now function.
Now, what about the old voltage regulator and the rest of the wires
going to it? The easiest solution is to just leave it in the car as
is. However if you want to remove it, please read on. Again, we
already know that the rest of the wires coming from the old
generator aren't to be used so they can be removed, taped back or
left connected. They can be left connected as there is no current on
them.
There are some other wires on the old regulator that would have to
be dealt with if you want to
remove the old regulator. The main ones of concern are the 2 wires
on the BATTERY terminal.
These are large wires and carry +12 Volts to the ignition switch. If
the old voltage regulator is to
be removed, these 2 wires must be spliced together to get the +12V
to the ignition switch.
If the old regulator is removed, there may be an issue with the horn
relay wire. Since Ford was
inconsistent from year to year with the wiring of the horn relay,
you will have to examine this
connection to determine how to resolve it if there is a
problem.
- If a warning light is not desired, the
orange wire may be cut off flush with the case of the regulator if
desired.
- Ensure engine block, alternator and
chassis are all grounded properly.
- Reconnect Battery.
- When engine is first started, it may
be necessary to rev the engine beyond idle to turn the warning light
off and initialize the alternator.
