good idea!!!! was busy at work and past this idea up completely...hehehehe ...you are removing the path...therefore isolating and determining which direction your problem might be ...if you remove the pos terminal off the solenoid...and you put a new fuse in ..turn the key...and it DOESN'T blow..then your problem is a shorted coil in the solenoid....if the fuse DOES blow when you turn the key on...then you have a wiring issue somewhere where you touching the frame with bare wire...it will give you a good idea of what to do next.remove the wire on the selonoid and install a new fuse, if it doesn't pop you have a bad starter selonoid. if it does pop check for a short.
