Description

Voltage Control Knobs for Diode Replacement on Internally Regulated AlternatorsThis is a voltage knob to replace diodes on internally regulated alternators with S or Sense Pins. The peak voltage will vary on manufacturer of the alternator you have. Rating is based off the 14. 8v pcm bypass regulator we sell and install in the denso based alternators we build. Some manufacturers will see 15. 2 4v peak with a 14v 14. 2v set point. With a 14. 8v set point from us youll see 16v max. You will wire these to S, and then to a relay off

This is a voltage knob to replace diodes on internally regulated alternators with S or Sense Pins. The peak voltage will vary on manufacturer of the alternator-you have. Rating is based off the 14.8v pcm bypass regulator we sell and install in the denso based alternators we build. Some manufacturers will see 15.2-4v peak with a 14v-14.2v set point. With a 14.8v set point from us you’ll see 16v max.

You will wire these to S, and then to a relay off ignition in the fuse box with a 5a fuse inline. There will be no individual instructions with the unit as every vehicle is different. Just generalized instructions to guide you through install. This is for people intending to charge higher than stock, so no, this is not a plug and play install.

These are generally in stock.

 

they work on up to 4 alternators of the same type.

there is no return policy on this item, it is built to order. Casing style is bare aluminum. 

it is internally regulated alternators that have an external sense pin, if you do know if your alternator has an external sense pin please research that, or ask the manufacturer of the alternator you have.

 

THIS DOES NOT WORK ON PCM CONTROLLED 05+ GM TRUCKS OR VEHICLES WITH THE 2 pin square plug!!! You need a 4 pin GM regulator for install!!! As stated there are no returns on this item, do not order it wrong. ASK if you can use this before purchasing if you do not know.

Noticeable Echo Reduction in My Shop
I installed these panels in a shop where sound tends to bounce around quite a bit. The panels were easy to cut to fit the wall and lightweight enough to mount with double-sided tape. The material feels dense and well-made, and I immediately noticed a difference in echo reduction. These helped dampen ambient noise without changing the look of the room too much. They don’t block out sound completely, but they definitely make a noticeable improvement in room acoustics.

Great Balance Between Aesthetics And Performance
These acoustic panels, made from high-density polyester fiber, are well-crafted and provide effective sound absorption without the bulk of traditional foam panels, helping maintain a clean and modern look on the wall. Installation is simple—just peel off the adhesive backing and press them into place. For added durability, I reinforced a few panels with small nails. They’re easy to trim with scissors, making it simple to fit around outlets or customize a unique layout. At only 0.4 inches thick, they stay low-profile on the wall while still offering solid acoustic dampening for their size. While they don’t deliver full soundproofing, the improvement in room acoustics is noticeable—voices sound clearer on calls, and there’s less echo overall. The neutral gray color blends in nicely with most decor, and the textured surface adds a touch of visual interest.

Amazing soundproofing
I recently installed the Soundproof Wall Panels in my home office, and they’ve made a noticeable difference in reducing noise. The panels are easy to cut to size if needed, and the installation was straightforward. The sound quality in the room has improved significantly, and I no longer hear as much outside noise or echo. Plus, the sleek black design blends well with my décor. These panels are a great investment for anyone looking to improve sound quality in their space.

Good quality panels
These are solid sound panels with a nice strong adhesive on the back for easy installation. I do think that, for the price, it should come with more panels. That said, good panels aren’t cheap and these are a good size. Perfect size for what I needed them for!

Perfect for my company's temporary needs
Color: Gray, Size: 72" wide, 66" Tall
My company ordered multiples of these dividers to separate desks in much smaller temporary space we had to use after our offices were flooded in August 2023. (Yeah, I know - just getting around to reviewing them now!) These fit the bill perfectly. Granted a bit of privacy so we weren't staring at the employee next to us. Easy to put together; excellent value.
