Variable Servotronic

[Dwayne Cosby <dccosby@interlog.com>]

When I get a chance, I've been meaning to make a variable servotronic
controller (not as complicated as the name implies). I figure I'll just a
wire a poteniometer in series with the servotronic controller, into an
empty dash switch blank (a la heated seat controls). That way I could vary
the assist from stock (full) to off (where it currently is - unplugged)
from the driver's seat. 

If anyone is planning (or has already done) this project, please post what
resistance range and wattage you used. Anyone with a Bently able to tell
me the signals on each of the servotronic pins?

Thanks,
Dwayne

Steve, If I remember my electronics education, putting the appropriate
value (and wattage)
resistor in series with the rack would decrease the assist according to
the resistor value.
Without doing some measurements, I don't know if that requires .5 Ohms
or 1K Ohms (or 1/4 W
or 10 W resistor). I suppose if you knew the resistance of the rack
(assuming just two connections
to the rack), you could figure out what kind of power was going though
it at 12V and pick the
right resistor and see if it "feels" right.
