There is a very good article by Larry Lytles in the September 1998 issue of
Classic Auto Restorer (CAR) titled 'Working With an HVLP Gun' from which I
quote the following: "...the reason I mentioned nozzle air pressure in the
first place was to let you know many do-it-yourselfers have lacked severly
it comes to having an air compressor capable of handling many HVLP guns. My
paint supplier tells me one of the toughest problems he faces is having to
a shop they lack the air volume to support the use of an HVLP. Which means
do-it-yourselfers don't even come close (despite the fact they can crank out
100 PSI air flow at the compressor)." The author goes on to describe in terms
of SCFM (Standard Cubic Feet Per Minute why there's a problem. Fortunately, he
offers a couple of solutions with the newest guns from Binks and DeVilbiss.

" does one check the polarity?"

OK Jan, first the background, you have a 53 truck. It should have a
positive ground 6 volt system. This means the positive terminal (usually
the larger terminal and painted red on it's top) should be connected to the
chassis. To test for polarity you will need a voltmeter (a cheap one will
do) and that is about all. Connect the + terminal to the chassis (ground)
and the - terminal of the voltmeter to the positive terminal of the
battery. It should read a ittle over 6 volts depending on how long it has
been since last charged. Now start the engine and bring it up to a fast
idle about 1500 RPM or so. The voltmeter should about 6.8 volts with a
light load on the generator, (like the park lights being on). now let the
engine idle, the voltage should drop 1/2 volt or so. If the voltage goes
up when you race the engine and drops when the engine is idling, the
generator is correctly polarized. Now that is not to say that it is
operating correctly, just that it is correctly polarized. Tell us what you
find, including what the voltages are with the engine idling and with it at
2000 RPM, then I will give you the next step to diagnose your charging
system. Don't forget to turn the park lights off 8 ) that is unless you
like to push your truck.

Subject: FTE Pre61 - faulty charging system

I've come across a problem in the electrical system of my '48 F-2. It
appears that the charging system has a bug. I removed everything from the
firewall when I sandblasted the cab. After putting the truck back
together and running it, a mechanic friend mentioned that I needed to
repolarize the field by short circuiting the 'bat' and 'armature'
terminals at the regulator "flashing?". The electrical shops in Calgary
confirmed this, but my manual makes no mention of this. I tried it. Now I
hooked my voltmeter up to the battery terminals. No voltage change from
zero to max RPM. These are the other measurements I found:
-From ground to armature terminal of generator (max RPM)-0.4V dc
-Ground to field - 0.0V dc
-Current in armature wire -0.0A
I beleive this means that my generator is faulty. However, I am curious as
to how the generator functions. I am familiar with a regular DC generator
(ie. stationary magnets, no extra field terminal). I don't understand what
the field terminal is for. Are the stationary magnets actually some form
of an electromagnet? If so, should I be testing for an alternating current
at the field terminal? Any and all help is greatly appreciated.

Subject: FTE Pre61 - '60 F-100 Turn Signal Schematic

NEEDED - '60 F-100 Turn Signal schematic.

Can anyone help me with wiring up my truck? The truck I have does not
have the original Steering column. When I got the truck it was
disassembled and the signals were not wired up. The column is from a
later year model truck so I will have to reconfigure the column wires to
control light blinking. I must complete this before I can apply for
registration. So, any help would be appreciated.
