Thanks for the input Jolly Roger, I did notice that my battery cable clamps are slightly larger than my battery terminals. I used some metal strips sandwiched in-between to keep it tight but it's still turnable by hand. I'll try maybe screwing with that if that problem returns....

Yeah... so the problem just went away. The only thing I did was use some Orange Blast degreaser to get the coolant/PS fluid off the battery cable running under the motor (driver's side) - that was two weekends ago.

It still did that.... one click... for about a week (last week), but after that... all of a sudden it just went away... It starts right up from the first try. I didn't do anything... I didn't even open the hood since two weeks ago so I'm really at a loss now.

Oh well.... I guess I can concentrate on finding that P/S and coolant leaks...
