Cables ARE growing a beard, but I replaced the battery last time I cleaned the terminals - even put on the protective felt and gunk kit. The corrosion still came back, leading me to believe the stupid thing is corroded all the way down.

I think I'm going to change the cables before I do anything else. At $20.00 in parts and a couple of hours in labor, it wouldn't kill me to do so. Even if it's not the problem right now, I think it will be a problem sooner or later if I don't get them fixed.

I'll keep you guys updated and let you know if that does the trick.
