How do I trouble shoot???????

I have no crank condition.....a couple of lights on the dash always lit as if ignition is on. key is out and all the way in the off position.

Battery is charged and at 12.3 (triple a guy)

I turn the key all the way to 3re slot where I would normally hear cranking and get nothing...no clicks ....zip.

I cleaned battery posts.....and blue neg cable to frame.

What else could cause this problem?

possible issue with the red Positive wires where they mate up with the battery?

Fuses or ralays?

I know there has to be a short of some sort since a few dash lights are on.

e brake and fluid on ...also when press clutch in i get the upshift arrow going on.

I opened the area up under the steering wheel an see the igintion switch and bunchs or wires.

Please HELP.
