The other day I went to start my FC while it was cranking, I noticed an arcing noise and my batt gauge was just hoping all over. After it started my batt gauge showed it was charging fine but when I hit a bump it the road it dropped to 12. Sometimes all the lights in the idiot cluster come on when I'm at a red light and the buzzing continues. I'm think it could be the ground to the engine or alt.
Any help would be greatly appreciated, thank you in advance.

 

Arcing inside the car can lead to a fire. Disconnect the battery and start digging around the fuse block to find out what the issue is, and do this before your car catches fire.

 

I'm on it, doing it as we speak any idea where I can find a wiring diagram?
