my previos post explains in exact detail how to jump that solenoid.
the battery cable goes to the BIG post on the left of the photo . . the first post next to that one should have just one wire on it.
leave the wire on that small post and connect the big front post to that small one with a short thin screw driver.
turn your headlights on, if they are "dim", so is your battery.
remove all the plugs and try to turn it over by hand or put a socket on the crank nut and turn it.
clean the posts on your battery and the battery ground wire where it connects to the engine.
