I’ve picked up some electrical noise that is seemingly coming from my power steering. I have a constant low frequency hum as well as what I can best describe as “pops” while the wheel is turned coming through the stereo. Experience tells me this is probably a ground issue but I’m unsure where to start. Before the G2 was installed I had rewired the console due to an RF noise issue that ended up being a bad patch cord from ebox to amps inside CC so I feel like all the grounds are good on that end. Any ideas how and where to start? Is there a fuse for the power steering on the G2 I could pull to disable it to see if that’s the source? Thanks.

Doubt that it's your G2 causing it.  No fuse that I've heard of.  I'm thinking wire bundling and insulation between them are where I'd be looking.

That old RF noise "problem" seems to still be there, and I wouldn't just say "grounds".

Just the "view from under the shade tree" though.  Experts will chime in as they recover from the holiday weekend.  Been pretty quiet on here.  [wink]

Check all of the fuses on your engine.

Thanks Phil. I had that problem cured just a few months before having the new motor installed. Someone previously had spliced RCA cables instead of using splitters. Over time the unions corroded and was giving all sorts of weird noises. They have all been replaced with new JL cables. Not saying that’s not the issue but the sounds come when the engine key is on or running and the wheel is turned.

Does your stereo/amp have clean power and a decent gauge/sized wire directly from the battery?

Or, is it just tied into a lower gauge power feed to the dash?

You can try adding noise filters to the stereo and amp.

Amps have heavy clean wiring. Stereo head unit is in ebox overhead and is powered from distribution block but with decent gauge wire. Gonna check all connections again and may add noise filters
