I am positive my car is having fun with me.

Today after a trip and parking my car, I decided to take pictures of the instrument panel to show the light out while the car is running and after turning the car off. Of course, after turning the car off the light never came on. I was excited thinking that the gremlin in my electrical system had gone.

It stayed off for 3 1/2 hours until I got back in the car to drive somewhere. When I returned and shut the car off, the light came on.

Because of this happening, I am now thinking it may be a relay/switch that is going bad instead of a constant flow of power from a wire or part. Am I thinking correctly? Of course I have never claimed myself to be a Master Mech by any means, hardly a novice DIY'er. Should I take this occurence as a problem with a switch?

Another thing I noticed today was a sound, not quite a click but more of a dull knock coming from the passenger side of the car near the foot well. It did it continuously in 3 second intervals. Where is the Over-Voltage relay located? I thought I read on the forum here that it may be under the floor panel on the passenger side.

I am attaching a photo of the Battery, Starter, and Altenator test conducted at the Firestone that installed my altenator.

Thanks again to everyone for all of your advice and feedback. I will take everything offered into consideration and give the feedbacks of the results.
