Am2 fuse keeps blowing

That fuse really only goes through the ignition switch and powers the coil and fuel injectors. It looks like if you unplug the Ign 7.5 fuse, that will divide the circuit to help diagnose. That fuse not only powers the coil but also the alternator lamp circuit. It could be possible for the coil to fail or the alternator to fail and cause a dead short. It's also possible for the ignition switch to internally crack or fail. Unplugging the alternator connector would remove that piece of the puzzle and still allow the engine to run for a period to see if it is a contributor or point more towards the coil.
