Mike, I’m wondering if the seminars for Funkstown, MD are a “Go”. I want to make sure that I don’t schedule anything else around June 8th, 2019 if it IS a go. I have entered my information but, have yet to hear back. Thank you.

Yes, we are OK to go for Funkstown on June 8th. We just announced it today and already sent everyone who did the pre-registration the actual purchase form. All RVtravel readers should have this in their newsletter Saturday morning.

I attended your RVillage seminar last week. I’ve a sprinter mh, using a surge gaurd model 34830. I hooked up to a pedestal in st Augustine. And got error message “open ground” Informed office and they sent maintenance. He tested and all checked ok. Looked at my surge guard and their was burnt spots on neutral. Cleaned it. Still read open ground. He then replaced the receptacle with new and retested, all good. Repluged in surge guard and still read open ground. He said because my surge guard looked burnt that it maybe faulty. I purchased new surge guard model 34930 and plugged it in. Getting error of open ground and rv off fault. Any ideas?

How did they test the pedestal after installing the new receptacle? Just putting a digital meter on it may not reveal the actual failure mechanism since there’s no load currents involved. And if they’re using a 3-light tester, these never put any real load on the ground wire, so it could easily be disconnected at the campground wiring between the pedestal and the incoming service panel from the power company. Sounds like something like that may be happening.

These so called “ghost voltages” on unterminated wiring are the result of inductive coupling between conductors run close together for hundreds of feet, which is exactly what happens in campground wiring. I was designing a 3-light tester using 100-watt bulbs a while back, and that’s what got me thinking about RPBG (Reverse Polarity Bootleg Ground) outlets and all the problems associated with them. Perhaps I should finish that design for campground pedestal testing. Let me think on that a bit.

Hi Mike, I’m with you that you should be getting paid for the shows & your knowledge. Too bad most of the shows wont even give you the basic room & board money! I’m betting that your ‘Live Webcast ” is going to be huge. Any chance we can donate to make it worthwhile for you? Maybe even charge a fee for the webcast? Seems to me that a few bucks spent to save your life is well worth the cost! Like you’ve said no one seems to be teaching anything about the electricity in our RV’s, either AC or DC. Ya you just pay your money for your RV & off you go with NO instructions on how to use your equipment, very sad!

We’re working on a way to monetize the webcast, either through some kind of sponsorship or a nominal fee to viewers. The best solution would be to find some sort of grant from the RVIA or other campground agency, but they aren’t interested in supporting me. Believe me, I’ve tried. Right now I’m getting hundreds of questions a week about RV Electricity, and I’ll have to quit my day job if I’m to have any chance of keeping up. But I can’t afford to do this without monetary support.

Could not get the link to the other seminar locations to open. When will you be doing seminars in the NW

I’m getting a lot of requests to do RV Electricity seminars all around the country, which is great. But Chuck and I are still working on finding funding to make them happen. Most of the RV shows pay their presenters nothing. That’s right, the Hershey RV show, FROG Rally, Alumipalooza, and all other shows and rallies I’ve booked so far pay me ZERO for the seminar, plus they won’t reimburse me for travel or even a hotel room. I did get some sponsorship support from a few manufacturers in 2018, but barely enough to pay for travel. If you know a rally or show you think I should attend, please contact their directors now and tell them that RV Electricity training is important to you and they need to find a budget so I can afford to come to their show.

I will tell you that the RVillage Rally 2.0 I’m doing this weekend in Florida is fully funding me to teach a seminar, which is fantastic. So if they can do it, then perhaps some of the huge shows out there can help as well.
