some of the wiring diagram attached.
The diagram shows #11 as being where the power comes from.
Looks to me like if you turn the light switch and take connector C151 and put the + probe of the volt meter on #11 and the negative probe on #15 (the ground). If you get no power try the negative probe a different ground.
If you are still getting no power then it is in the light switch or the connector to the light switch.
If when you moved to a different source of a ground you got power then it is the #15 to ground that is the problem.
