FYI....In jrsavoie's thread about the WTS ghost, I had mentioned that I had been Ghost FREE for about 1 1/2 yrs.
The other day it got so bad I couldn't keep the rig running for more that 3 blocks...
Sure enough, I'd climb up on my push plate and wiggle the 2 (black) grounds that come out of the harness at the rear stud location.....One wire is thicker than the other and they are both on separate eyelets....Also the SES light was dim and flickering and the STS light didn't even come on, only if the WTS light decided to flash.
Now to look at them, you'd never tell they were any problem that could be associated with them, (But from experience, I know better).....shook and limped back to get some tools at a friends, took the nut off and removed the 2 grounds from the stud.
The wire, eyelets, and crimp were all tight and looked fine.......Now that I inspected the wires and connections, I proceeded to wire brush the Stud, eyelets, and the nut to a spectacular shiny polished aluminum finish, reconnected the 2 grounds and tightened them down......Guess what it's been since last Thurs and not a WTS ghost in sight.
FYI-BTW.....I didn't even touch the 2 that are bolted to the tranny dipstick.
2 Cents......Take from my experience what you like.......I've been a WTS ghost victim since way back in the D Place days when GMCTD said "Clean your grounds!"
