Hi there, I'm URGENTLY in need of some advice. When I try to key the starter motor, absolutely nothing happens. Good battery, no click at all, following normal gp and dash light behavior.

So, I was very happy to find loose solenoid cables, but tightening them is a real puzzle. There are two 17 mm nuts visible. Both will move with minimal torque, but THE STUD / BOLT? INSIDE MOVES AS WELL. SO DOES A SECOND, SLIMMER NUT ON THE REAR SIDE OF THE TWO EYE TERMINALS. Can someone explain what this configuration is and how I should deal with tightening it up. I don't see how I can get any purchase on the inner nut, esp. with access so poor.

Also, playing with the shifter hasn't made any difference.

Thanks!!
