[AT] 430V

[Dean VP]

Tom,

Absolutely. Use as heavy gauge cables as can be found. Typical jump start
cables are not really good enough but might work.  Stall current is very
high and small gauge cables will drop a lot of voltage.  Not good.  12v
times High Amps = High Watts = Huge Torque

As long as Dean agrees with me, why not  give it a shot with the starter. 
All you want is a  brief tap. Watch closely for any movement. If it moves at
all, stop and try to pry it back a little and try it again.
