It says the Autoformer starts boost at 116 volts. maybe your meter and the voltage detecting portion of the Autoformer aren't quite in sync.

Interesting, my original paperwork says 115. One volt difference no biggie. I'm not going to sweat it.

The voltage coming out of your generator should be spot on versus what is supplied from the RV park.

I have a Power-Master Voltage Booster so I am not much help with the Autoformer.

Ok I did that and success! Had the gennie putting out 120 VAC and plugged in the Hughes. mber light came on with the red boost for a second or 2 and went off like its suposed to. Thanks for the tip.

I was in an older park last summer. There were a good many construction workers in the park. I could watch my voltage monitor and see the HAF kicking up slightly when they all got home and turned their A/Cs on. In this case it was giving a little higher voltage on "boost" than the normal voltage was.

I have never experienced any "dimming" of the TV or any of the other appliances.

You just really forget that it is there, it works so well!

Typical Volt-Ohm meters have a 2-5% accuracy. Check the technical specifications of the meter you have. This can effect your measurements. Good comments on checking out the operation of the Autoformer. Very knowledgeable people here.

Glad to hear that your Autoformer is OK.

I never trust any power coming from any pedestals. That's why I ALWAYS travel with a PowerMaster and the Progressive Industries EMS HW50C units hooked up in series directly after my shore power cord and before the transfer switch.

Thats what I figured if there was a % tolerance in the readings. I used 2 separate Fluke meters and got the same readings so I became suspicious. I burned up a few a/c units thru the years thanks to low park voltage but this is plugged into my house. I think all the Christmas decorations are eating the current!

This system will have multiple voltmeters and indicators, and perhaps ammeters as well (Depending on if I can add them without voltage loss)
Incoming voltage pre-autoformer incoming voltage (well output of transfer switch) post autoformer, current (out from transfer switch) and possibly in from shore. and a simple NEON indicator for 240 volt. across the legs. Status at a glance.

That's a heckuva idea wa8yxm. Build two of them while you are at it and I'll buy one off you.

Fossilhog,

At least your AF has boost lights. When I bought mine several years ago, Hughes stopped installing them on their units. Now I see they have them again....story of my life!

I can't begin to tell you how much I've learned from people in this group. There's no end to the knowledge and advice. I got my basic electrical skills back in the 60's while in the Army at a Pershing Missle base. I was a generator tech. Never thought it would come in this handy!
