98 Suburban wont start...

Heres the story from back to front:
I have been driving a 1998 Suburban, 5.7L, 144xxx miles, as a backup vehicle while I finish working on my truck (which is getting the turbo treatment ). Last Saturday I went out for a while, came home without experiencing any problems with starting or running, and parked it for about an hour. Tried to start it later that night to go get something to munch and POW, the truck wont turn over. I assume its the starter sinces its been cranking slowly (but not super slow, just slower than usual) every now and then. Get a new starter, put it on, cant get it to crank still, assume Im shimming it incorrectly, go get my old starter benchtested by a local expert and discover my old starter works fine. Reinstall the old starter, still wont crank, take the battery to Autozone, discover the old battery isnt any good, replace it with a brand new battery, still wont start. Take off the alternator, take it for a test at Autozone, find out the alternator is good. All the battery cables look good and I cant see any binding or breaks in the wiring. So after all that Ive still got a Suburban that wont crank. ...Any ideas? Please? Ive tried to run a wire from a starter bolt to the negative battery terminal to see if maybe a ground came loose, but that didnt help either. Thanks in advance.

I have seen side terminal battery's that have corrosion inside the cable ends insulation at the battery. Gotta cut it open to see it.

Does this truck have the stacked wires at the positive terminal of the battery? This has got to be one of the worst designs I've ever seen from GM. My 1999 K3500 has this "feature". There are two problems that cause a no-start for me. First is corrosion between the two lugs on the wires. The other is that the lead spacer between the two lugs gets compressed and eventually does not make good contact. Check these parts closely.

If you are using any of those replacement cable ends, all but a very few good ones will look perfect and feel tight, but will have enough resistance to fry an egg!

Similar thing w/some of the adapters for top to side, and vice versa.
