 2 batteries, 1 a HUGE tugboat battery (for the winch, and starter) 1 a
big deep cycle for the other stuff. Both less then a year old, brand spankme new
gm 12SI alt with a large isolator between the batteries. The surge happened with 
either or both batteries with or with the isolator.

 The reason I was watching the V+ was I had 2 new cbs die and the store wasn't 
happy about the warrantee replacements. I wish that I had captured the waveform 
but the dvom only did max/mean/low dataloging
