I am not myself familiar with Ford systems but according to the Mastercool
manual there are Ford systems (FFOT, no idea what this means) that are
supposed to cycle the clutch, but not as fast as you are reporting. This
does appear to be a case of low refrigerant. Basically, these systems run
until a reservoir is full of liquid refrigerant, and then rest until it is
exhausted. Typical cycle times are 2-3 times per minute at low ambient
temperatures up to continuous running at high ambient temperatures. Yours
is cycling much faster than this and probably low on refrigerant.
These Ford systems appear to be a little "different" in operation so maybe a
Ford news group might be a good source.
Although I recommend a full manifold gauge set, there are setups
intermediate between what you have now and hi-low gauges. A few years back
I got a low side coupler, hose, gauge, valve and can tap from J. C. Whitney
pretty cheap. I have seen similar rigs at Autozone. This lets you view the
low side while filling at the same time. It doesn't show the high side, but
it is a lot better than filling "blind".

Re: Charging my Air Conditioner
Just double check the low side switch, as I didn't know the low pressure
didn't work correctly until the next summer, (with help from a friend) after
I had used up seven hundred dollars of R12:
http://www.----------.com/R12.jpg All I knew was I needed to jump it in
order to fill, where the normal cycling was enough to start the fill in the
past.

Re: Charging my Air Conditioner
Just double check the low side switch, as I didn't know the low pressure
didn't work correctly until the next summer, (with help from a friend) after
I had used up seven hundred dollars of R12:

order to fill, where the normal cycling was enough to start the fill in the
past.

Sometime too if the hose is long enough you can put R134a can in a pan
of hot water while trying to draw vapor from it because as liquid
boils to gas in can it cools it a lot and when this happens the
pressure in can drops and slows things down a lot on charging. The
idea of flipping can as above is not a bad idea as I do it but limit
is to a few seconds or so at a time so you do not get a slug of liquid
in compressor.
