Alternator Whine VR 5L

[someguy360]

For anyone curious I finally got the issue fixed late last night.

My Steps:

* I re earthed the amps with bigger cables to a better spot.

* Ran a new 4 Gauge earth from - Battery Terminal to Body as the factory one was pretty woeful'

* Replaced the crappy braided earth wire from the alternator to body that comes standard on the V8's with a fresh 8 Gauge wire.

* Earthed the headunit to the chassis

* Swapped the amps with spares

None of these things made any difference.


Did some more searching and found that the only thing left was the ground track inside the actual headunit could be blown......so I ran a wire from the RCA terminal on the headunit back onto the chassis of the headunit to make a small RCA earth and it fixed the problem straight away.... (would expect this problem on a pioneer but not a JVC)


Happy there is no more noise but not happy that my brand new JVC headunit has had this issue straight out of the box so I will be calling JVC to see if there is anything they can do, but either way its fixed for now

Glad to hear you fixed it.
Agree that you would expect this with a Pioneer, not with a JVC.

It was probably fine out of the box... it usually happens during install.

-edit- You will often find that the install manual will tell you to disconnect the battery when installing the headunit. By doing so, you will eliminate this from happening on those rare occasions. This is their disclaimer for getting out of fixing it under warranty....

Mind you, I don't think I've ever met anyone who has disconnected the battery during headunit install.

Personally I would have put in a ground loop isolator first, that would have saved you a lot of time with re-wiring and whatnot... Glad to hear that it's sorted now tho

Ground loop isolators areprone to killing the quality of sound and only used as a last resort.

Would rather lop of my left nut than use an isolator
