A couple of stupid questions

Posted by Less On 2008/10/8 21:31:14

I just purchased a 1947 packard (2112). Everything worked in the car including the clock. I replaced the master cylinder and now the courtesy lights are not working when you open the door.... I can't see how these would be related, I searched the forum for a wiring diagram, but have not found one for the interior. Is there something simple I am missing (i.e. a fuse, switch, etc).

Also mounted on the dash is a clear 1/2 moon shaped magnifying glass (for lack of a different term) with the words "the guide" on it. What the heck is this for?

Thanks in advance & sorry for the stupid questions....
