Volt meter just stopped.
 

I've got a 77' 280Z. ˆjust noticed today that the volt meter is reading below 4 (the very bottom of the guage). i know it still is getting power, because the red charge LED lights up when i start the car. Is there an easy way to get this out to see what the problem is. the car starts and runs fine, so i know its the guage. are there some wires i can check?

I also noticed that the hazard flashers are no longer working. someone please help me.
