Rory,
   It look like you may have found what killed your first
stabilizer -- a short circuit in one of the instruments or
senders.  I would suggest disconnecting the power then
putting an ohmmeter on the line to the instruments (where
the output of the stabilizer connects) and measuring the
resistance while moving a few wires around and then
disconnecting each gauge that runs off of the stabilized
voltage looking for a 'reasonable' resistance.
   As I understand it, the stabilizer is NOT a resistor
divider as is used in other cars but rather a s_l_o_w
vibrator that pulses voltage to highly damped gauges.
It should NOT smoke under any circumstances unless
the load on the circuit is way too high.  I=E/R still.  Current
is inversely related to resistance or load.  If 'R' gets low, as in
a short circuit, then 'I' gets large and invents smoke. :-]

Best,

rick
