By Mike Sokol
We’ve all had a lot of challenges this year. As a personal example, I had more than a dozen RVelectricity seminars scheduled around the country in 2020, including the Hershey Show, the FROG rally, and teaching electrical safety classes for Lawrence Livermore National Laboratories (no kidding). Here’s a pic from my last Master Class Seminar in Live Oak, FL, with 300+ attending each day for 3 days in a row. What a great class!
But all my live events were then canceled due to COVID-19, forcing me to reinvent myself. However, I’m lucky since I already had video cameras, microphones, lights, computers, and every kind of editing software you can imagine. Yes, I teach audio production techniques as an adjunct professor, as well as write about audio-video editing and production for a number of pro-audio magazines and websites. You guys know I’m really just a sound-guy posing as a teacher, correct?
But it hasn’t been easy. I do miss the seminar crowds, and visiting the rallies to meet my readers was one of the highlights of my road trips. Still, I’ve learned a lot about virtual teaching over the last 8 months or so, and have turned it into a powerful tool. So when I do get to restart live seminars sometime in 2021 (fingers crossed) I’ll be live streaming them for the rest of the country as well. I’ve already discussed this with the various show promoters, who all love the idea. As ZZ Top writes “I’m Bad, I’m Nationwide.”
Now, this type of remote learning would never be possible without millions of RVers who are currently watching Zoom classes covering thousands of topics on their mobile devices and computers, which means that you are the ones actually driving this technology. So even if I don’t see you on the road in 2021, I’ll see you in one of my virtual sessions real soon.
Let’s all keep safe and meet in 2021 – either virtually or face-to-face. I can’t wait…
See you on the road. Let’s play safe out there…

Hughes Autoformer testing – Part 3
I’ve just gathered the next set of voltage and current measurements showing how the Hughes Autoformer works with a 15 kBTU Dometic Penguin II air conditioner, this time using the stock starting capacitor.
It’s now operating with the voltage/current boost ratios that all my textbooks predict should happen. By itself none of this data is conclusive one way or another in terms of reversing the NEC decision to ban all booster transformers from campgrounds as of the 2020 code cycle.
So now I have to do several sets of experiments with and without the Hughes Autoformer in-circuit to determine if it creates too much extra current draw in a campground, or if it actually can reduce current draw from an air conditioner that’s operating on extremely low campground voltage.

Be like Mike! Use this 3-light and digital voltage tester!
Mike Sokol says: “I found this nifty tester online and have been using it in a variety of voltage checking situations. It performs all of the 3-light tests for outlet polarity, open ground, open neutral, etc., as well as being a 3-digit digital voltage indicator. In addition, it performs a standard 5 mA GFCI safety test – which you should be performing on all of your GFCI outlets once a month (or at least once a camping season).” Read more about it here.
Last month’s survey results:
Interestingly, nearly 1/4 of you actually pull your RV batteries out and keep them in your garage or basement. That’s a lot of heavy lifting and rewiring to be done. I will note that in the springtime I always get a lot of emails from readers who can’t remember how to hook their batteries up correctly. Or, even worse, they get the polarity reversed and swap the positive and negative terminals. At the very least that will blow fuses in your converter, but it also has the potential to fry a lot of your other 12-volt DC electronics.
So if you are planning to remove your batteries for the winter, make sure you mark all the cables properly with white electrical tape and a Sharpie marker, take a lot of pictures, remove all metal jewelry, and be careful to loosen and take off the negative battery terminals first.
Don’t be like this reader who got his metal bracelet trapped between the alternator wire and the chassis. That was a painful lesson – with the scars to remember it by. In fact, 12-volt DC systems can be more dangerous than 120-volts AC just because of the huge currents (up to 1,000 amperes) available during a short-circuit. Read more about staying safe while working on batteries HERE.
I’ll be sure to publish another article about replacing batteries in the spring – just in time for you to reinstall them. But in the meantime, I would suggest you get a battery tender, leave the batteries in place (after checking for electrolyte level, of course) and avoid the strain on your back. Batteries don’t mind the cold … they just don’t like to be discharged completely and sit for weeks or months. That’s what kills those batteries.
Ring video doorbell for watching the elderly
Last year I picked up a Ring video doorbell to help watch my 91-year-old father, who lives alone. Here’s what I’ve learned so far.
After we lost Mom over a year ago, we moved my dad into a townhouse very close to me. When he took a big fall we also got him a fall-alert system which has alerted us a few times when he tripped in the house. But I was worried about him going to the mailbox across the little street and not coming back, or even locking himself out of the house when he takes a few steps to get his paper in the morning. This concern was compounded by my scheduled cross-country seminars, where I would be gone for days at a time teaching RVelectricity classes.
So I thought that a Ring video device on the front door would help give me some peace of mind, especially when I was 1,000 miles from home and Dad wasn’t answering his phone. Perhaps you have your own aging parents who you worry about while you’re out camping or on business. Well, the most basic Ring camera costs around $99, connects to your existing doorbell wiring or runs off its internal battery, and links to a Wi-Fi router in your home. For a $30 per year service fee, Ring will keep recordings of whatever happens at the front door, sending an alarm to your cell phone no matter where you are in the world. And it will also let you know (from thousands of miles away) if there’s been a report of neighborhood break-ins.
The latest Ring video algorithms are great since they allow you to set the sensitivity and trigger area – including waiting for a person-shaped object in visual range to start the recording and send an alarm to your smartphone. And, of course, it’s great at recording when a delivery person drops off a package at the door and rings the doorbell. You can even talk back to the person at the door using your smartphone and the built-in speaker in the Ring device.
Now, my dad can’t operate this since he still has his 10-year-old flip phone, so I have it linked to my own phone to help watch over him. This is just one more tool to help keep your parents or other family members safe while you’re on the road for business or fun.

Q&A’s from my readers: November 2020
I’m getting a lot of interesting questions from my readers, many of which are on my RVelectricity Facebook Group. Here are a couple:
Q1: Long time since I last talked with you. I keep seeing your articles referencing the neutral bonding issue, which you and I dealt with almost 8 years ago, before you created your own dummy plug for sale. You instructed me on how to create one, so I created one the next day and it’s worked great since then. However, there is one minor drawback that frustrates me. I can’t use both of the 15-amp outlets on the duplex on the generator, since the bonding plug takes up one of them. …
Q2: I read your article and have attempted to put a battery cutoff switch on our 2011 Newmar Bay Star without any luck. For the house batteries, I have two 6-volt batteries in series, as your diagram shows. I ran a battery cable from the ground to the frame to the switch, then from the switch to the negative terminal (where the other negatives are all connected).
When I turn the knob to the OFF position, everything works, same as when it is in the ON position. Very confused why it does not work…

Mike’s Video Quick Tips
By Mike Sokol
The Christmas season can now officially begin because my wife, Linda, has finally heard the “Snoopy vs. the Red Baron” Christmas song by The Royal Guardsmen. She listens for it every year and says that she’s not in the mood for Christmas until she hears it. So what is so special about this song, and what can we learn from this precocious beagle and his arch-nemesis, the Red Baron? Well, it’s about fierce enemies declaring an unofficial ceasefire.
