I checked on that 1979 F-150 two wheel drive "PACE TRUCK" with the 460
today. It was gone...somebody bought the entire truck to restore. I
remember that the only thing that was missing was a headlight....it too bad
that it's gone. But......at least someone is restoring it back to stock.
They look neat too!!!! It was black, silver, & red with "OFFICAL PACE
TRUCK" stickers on the door. It was badley rusted in the bed but otherwise
the cab was in good shape. Well enough of my B.S. ing!!!!! Wayne Grabley

" I'm in the process of putting a '54 F-250 back on the road, and while I
won't be converting to 12 volts immediately, I will be looking into it by
spring or thereabouts. Hence, I am on a fact-finding mission.
I'm considering two alternatives: convert to the '56 and later 12 volt
generator and stay with the original look of the engine compartment, or
converting to a Ford alternator like the spare I have for my '65 Comet. I
already know I'll have to make other changes to account for the reversal in
polarity, i.e. a new starter and heater motor, etc, but I'm a lttle fuzzy
about wiring up the new generator or alternator."

Your desire for reliability is understandable but it turns out you cannot=
readily compare the gen and alternator for this characteristic. Let me=
explain, the alternator contains no commutator. The commutator and brushes=
are the primary cause for generators failing (I know, they have bearings=
but so do alternators so that is a wash and the bearings usually last 5 or=
10 years). Alternators have silicon rectifiers which can last much longer=
than commutators under normal conditions. Also the brushes in alternators=
run on slip rings not commutator segments so they last much longer. So an=
alternator will generally outlast several generators, BUT the silicon=
diodes in alternators are not very robust, and just a fraction of a second=
of a jumpstart cable connected incorrectly can destroy your diodes but=
would not bother a generator at all.

So take your pick, on my vehicles I stay with the original, however I have a=
47 pickup that I am going to start restoration of soon and it probably will=
be converted to 12 volts generator powered (neg gnd of course). As far as=
the polarity reversal using a negative ground vs the positive ground of the=
54, that is no problem. The only thing you will need to change is the=
wiring to the ammeter will need to be reversed. The heater, wiper (I=
believe yours is electric), and starter motors do not care. They are not=
PM type motors so they will run the same direction no matter which way you=
connect the power. The guages (except the ammeter) are a thermal type=
guages and they operate the same with either polarity. Even the radio (if=
you have the old tube type radio) will operate the same with either=
polarity in most cases. There are a few rare exceptions, that I do not=
want to try to explain at this time. Even the voltage regulator works=
fine, but you must polarize the generator for the system you are using.

The voltage change is another problem You will either need to find 12 volt=
motors to use for the heater and the wiper, or use a dropping resistor with=
them (not a very good solution). Finding these should not be a major=
problem since the 56 cab was quite similiar to the 54. The starter and=
solenoid will do just find on 12 volts if you don't crank on them for long=
periods (I have used this on my tractor for over 10 years and have never=....
