Alternator Noise

Got ferrites all over the place. Zero benefit.

Where else do you have ground straps besides the door hinges?

A picture of your door hinge setup would be helpful since we both run fiberglass trucks.

 

I have not checked with antenna coax off. I'll try that. I am direct to battery now (wasn't before). Before, I was powered through breaker box on my 2018 and had a little bit of noise. Now in a 2020, direct to battery, MUCH more noise. (And what I am calling alternator noise is a noise that increases in volume and pitch with increases in RPM. May not be alternator, but that's just my assumption.)

 

Yes, both NB/ANL.

What I didn't mention before was that I only just changed out the stud on the mount last night. My old stud was damaged when my Skipshooter hit a construction sign in Denver. Wind was from the right and I was in the left lane, so it was sticking out to the left quite a bit and those lanes are so narrow as it is. Anyway, it was causing a short to the mount.

Today has been my first day out with the new stud and there's considerably less alternator noise. So. Weird!

I had already ordered the Powerwerx noise filter and will install it when I get home. I have the ground straps with me. I'll try that but in my last 2020 (last year, previous company), it didn't help much. But who knows? Every truck is different even when they're the same.

FWIW, I'm connected to the battery furthest to the left when facing the driver's door and battery box. In line fuse of course on the hot side immediately after the wire leaves the battery. The one furthest to the right is where I've hooked up my 2500W true sine wave inverter. I assumed with no science to back it up that keeping them on separate batteries (even though they're wired in parallel) was a good idea.

 

It's always on because it's always in use. It's powering things that need to start on like my dorm fridge.

I got this stud: Super Heavy-Duty CB Antenna Stud

Video talks about the right-angle certain l version but it's the same size as the regular version I have.
