Okay,We all know how much the tilt sensor's pretty much dont work on the strats.Im not going to sit here and write a 30 minute guide on how to do this,I like to keep it simple.It took me all of 10 minutes to do this...5 of that was opening the guitar.
Step 1. Open your guitar
Step 2. Find your tilt sensors *Refer to pics*
Step 3.Get all the glue that is holding them in place off,so you can unscrew the two screws.
Step 4. Lay the offending tilt sensor... on its side...as shown below.

Step 5.Make sure you "Snap" the sensor into place,I have no glue or anything holding this in place,If you work with it you can get it to snap in place.But if you want you can tape it in if you want.
Tada...thats it,Enjoy your HOPEFULLY fixed tilt sensor.The guitar should tilt at about a 70 degree angle or so now.Its not SG perfect but its damn close.
Another angle of the finished fix.
