1970 Super Bee elctrical questions

Hey all I have to do the unthinkable. I have to work on a MOPAR lol. My Father has a 1970 Super bee and he is getting old and can not work on the cars anymore and I am gonna go work on it for him. His problem is 2 things one when you push in the clutch key off it turns over and when key is on and car is running the guages are not right so he says. I have not seen the problem yet. Before I go over there I was just wondering if you Mopar guys might know of a notorious problem with this year car? I am kinda ground/ ing switch its hard to say with out seeing it. The car has a 383 4 speed all original no add on stuff just stock.

It was the ing. switch put a new one in and worked great!
