So, I am currently putting in a finalized sound system in a 1998 C5 corvette. I finally put the whole thing together( 4 speakers, hooked to an Alpine amp with RCAs. And a amp included sub box, the basic Dual box. It took me all day and I finally got it wired throughout the car. Here is the problem, both the amp and the sub are grounded to the drivers side factory ground but. When I reconnected the battery and turned it on to test it however, the ground was not tightened down well. Now the lower fuse box below the passenger dash makes a very strange sound and while the vehicle is running the power gradually drains the battery to zero!!!!! I'm completely at a loss someone please help.

  • Is the sound a rapid ticking sound oe more like a buzz? Does it continue having issues with the ground terminal fully tightened? May 31, 2018 at 23:07
  • Yes, that is exactly the sound. And I think I got it, the belt fell. Therefore, no power to the alternator. I have heard C5 corvettes have infamous problems with their flywheels throwing the belt.

  • Check the ground point that wasn't tightened: due to arcing, the metal surfaces may have been damaged.

So I might have found a solution! Cars have these crazy things called alternators. Well I googled the issue and most people seem to say if you are having this problem its because the alternator is bad. Well I checked mine and the craziest thing, the belt had thrown itself..... In the garage.... wow. Anyway, if you have problems sounding like this check the alternator. If I get the belt back on I will see if things get better.

  • What nonsense diagnostic testing did you begin with? Had you started with the missing serpentine belt we would have guided in accordance. Obviously alternator recharges the batteries connected to the car. The belt failing had nothing to do with your mediocre grounding and electronic connections. More likely there are far more underlying issues such as a stuck pulley bearing which refused to let the accessories work. You would also notice the water pump not running and engine heating up rather quickly. But you did not mention this. Adding on, even the steering pump, AC and heat would not work. Apr 1 at 0:27
