Also have problems with 2005 Ranger inertia switch. Looks like previous owner has replaced it once -- electrical tape on wiring. Too cold and windy to look any further today.
Just wondering, has anyone eliminated the inertia switch by going to a oil pressure cut off switch instead? (Low oil pressure = off) Or maybe wiring into the airbag system somehow? (Airbag deploy = off) Sounds a little safer than eliminating it entirely.
Although I basically sit on the gas tank of my Kawasaki, and used to sit in front of the tank on my MGB (with electric fuel pump that REALLY knew how to give you fits!) and my old '54 Chev. pickup. (converted to 12 V & fuel gauge burned out -- reach behind seat and feel tank to see how much fuel was left -- worked great in summer -- not so good in winter)
