Locobob's Interior Mod Thread

[Locobob]

Been reading up on alternator whine. Thinking of trying a new ground for the head unit, running it back to the storage bin where I just installed a really solid ground - this is where I would ground an aftermarket amp if I get one someday and from what I reading its best to ground all stereo components in the same location.

Robert,

First class engineering and wiring...

VERY IMPRESSIVE!

Wish my interior looked like that. That is beautiful, Robert!!

Still trying to get rid of the alternator whine. At times its very subtle and I can barely hear it, other times its quite loud. I think the volume of it may be related to electrical load, seems louder when the headlights are on. I tried changing the ground point for the stereo but that didn't help any.

I will be wiring in the capacitor this weekend. The one I had on the alternator got lost during the engine pull, disassembly, reassembly and reinstall.
I'll take some pics and post. Capacitor trick works!

Bob, When I did my head unit I had a horrific whine. I added two PAC SN1 Noise isolators and it resolved my issue.

Great I'd like to see that, are there any downsides to doing this?

I've been considering a noise filter, did it hurt sound quality any?

I had it on 79 L48, 91 ZR-1 and 94 ZR-1. No down side I ran into.

Sounds like a plenum pull though... unless I can plumb it in back where the alternator wire connects to the battery.
