RE: responses to my F250 starting problems

Thanks to everyone who has responded to my initial post!

For the person who asked me to clarify what I meant by "won't turn
over"...when I turn the key initially to heat up the glow plugs before
actually starting the truck, both the voltometer and the oil pressure gauge
snap down to zero. Then, once the "Wait to Start" light goes out, even if I
try turning the key all the way to start up the truck, not a thing happens -
no noise, nothing. It seems there is a drain on the juice somewhere, whether
it's a bad/dirty connector or just a bad battery.

Thanks, Felix for mentioning the Schucks option - and yeah, I know these are
heavy duty batteries, so I'm prepared if it comes down to shelling out cash
to replace one or both of them.

I won't be able to test everything out until sometime late next week or
possibly after the long weekend, but I'll put a post up when I find out
what's going on.  It's always good to have a resource like this. Thanks
again!
