I would agree with checking/cleaning/tightening up the connections mentioned, as well as the negative ground side.

As far as insulation barely grounding out, well....consider what your welder set on DC does. With all those amps available in the battery just waiting to find a ground - even a weak one - a small arc would almost instantly weld itself to ground. Then, you want to talk SMOKIN' hot cables! Ground out a battery and you can get instant 150+ amp draw.

I guess next time I drive mine, I'll have to see how hot my positive cable gets. Might just be normal for these cars for all we know.
