Hi,

 

This question is for a 2022 Silverado LT (refreshed interior) with a 5.3 L V8.

 

I am getting ready to run some 10 gauge red/black zip cord through the firewall on the passenger side and connect it to the battery.  This is my first experience with a vehicle with a Battery Management System.  I will be connecting the red part of the cable directly to the positive post of the battery, but I am unsure if I should connect the black wire directly to the negative battery terminal without going through the current sensor, or should I run the black lead through the sensor ring?

 

At most, the transceiver would be running 100 watts output and according to the radio manufacturer, the radio pulls about 22 amps when it is putting 100 watts RF into the antenna.

 

Thanks!

If it were mine, I'd run the current through the sensor, just so the ECU knows how much is being used so that it can charge the battery accordingly. From my experience it seems they put fuel mileage as a priority over battery life. I'd personally prefer that reversed, but this is the world we live in. That's my reasoning for going through the sensor - the battery is going to need all the help it can get to make it just 6 years (When they used to last 8-10 on average without electronics).

Here is an article that may be useful for your project in case you haven't seen it already.

Here is one sentence that is  in the article.

 

It is imperative that the ELD not be bypassed when wiring amateur radio equipment, so typical wiring recommendations found in Owner's Manuals should not be followed!

FYI Duelin, I got a 404 on that link.

 

Ahh, I see what happened - the link got posted twice right next to each, so it's trying to go to the double address.

Thanks.  Very familiar with k0bg's website, although I admit it has been a while since i perused it.

 

Again, thanks for the input and the referral to refresh my brain cells!

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.

      I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w

      I took a 12 second video on my iphone but the file is too big to upload. I will have to figure out how to extract the audio or just do another start with an audio recording.
