electrical weirdness

Hey all! I was having major electrical problems. P/S surging, ABS turning off and on. Shift lock solonoid clicking. I searched and searched, trying fuses, measuring voltage drops. Finally took it into the dealer. They spent several hours and then finally, accidentally found that the battery ground to chassis right at the base of the battery tray was bad. It's the only place on my car which has corroded, and it corroded so bad that the connection was only visual. Keep it in mind.
