..and as for the "lack of voltage within the loop", I forget where I saw it, but someone noted that (at least with 775's) there is some kind of voltage leak once the CPU is locked down. The voltage is actually traveling through the IHS into the CPU block, I'll see if I can dig up the link. Auto's actually use a grounding strap from the engine to chassis, this along with a much higher concentration of anti-corrosive (anti-freeze) is what prevents most problems in autos.
Yes voltage thru the cooling sys is one of the causes of electrolysis.
I am not sure how much is in a computer w/c,ing sys but i can check tommorow.
I will bring my fluke 88 home.

In a car cooling sys (ASE) says no more than 0.5 volts i believe.
The TSB for that came out years ago and i honestly cant remeber.

The grounds in automotive sys,s is where some of the current comes from.
Yes grounds DO carry current.

The simple way to tell in an automotive sys is to squeeze the hoses, if they crack they are shot, from electrolysis.

Now i wouldnt think a computer sys would do the same for many,many years.
