For what it's worth I checked around 6 or 7 ground spiders on my 07 ( 60,000 miles) and didn't find any corrosion or heat damage.
I run heated gear, magnum blasters, gps, and aux lights; off of a fuse block. Regularly ride in the rain too.
vabrzn, this post is not aimed at you per se, but please note my experience below:
I have, only a few months ago checked all the ground spiders on my '07 with 76k. All the spiders and their connectors were in perfect condition, the metal was shiny and the plastic nice and white. I spayed the inside of each connector with electrical contact cleaner spray and applied liberal amounts of dielectric grease to all the spiders and their connectors.
From what "we" knew at the time about this problem the above procedures were supposed to be the complete fix. Well today the front left spider (the usual suspect) decided to make my day more exciting than it was up to that point but "killing" my bike about 1/2 way through a left turn at an intersection. Luckily I didn't panic and had sufficient momentum to coast through the remainder of the intersection and to the side of the road. Also lucky is the fact that this happened today/now and not a couple of days ago when I was riding up in the mountains of GA/NC/TN.
For the record, I'm running the fixed ignition switch and the Broadie relay.
I will be performing the fix (and this looks to be the final solution) described by Bob/S76 documented here:
Ground Spider By-pass
And the Smitty solution of soldering all the spider wires I can easily reach, which I guess means all but the two under the front cowl that Mcatrophy showed.
