I have a Honda 1000 watt genny. It has a 12v battery charger built into it. Does the Yamaha 2000 not have this feature?

Don't let anyone fool you into thinking so. Everyone needs to learn what an open neutral is.

Can you be more specific about this comment? Please see the link in post 8 above. My unit detected an open neutral in a KOA park in the US.

Open neutral 30 amp is a whole different animal than open neutral RV service 50 amp. Nonetheless a warning is something other than a service disconnect.

Would one of these outlet testers be a good idea for testing before you plug in?

Supplementary instructions: If it explodes into a ball of fire when you plug it in, do not plug in your trailer.

I'll defer to an electrical guru when they check in; this will give you some info when you plug it into a receptacle, but I don't believe it will tell you that you have an open neutral that will result in the voltage to the trailer being 240 volts instead of the 120 volts that you want. Ie. the tester does not measure the line voltage. So the answer to your question is yes, it is a good idea to test, but this tester does not measure the line voltage. For this you need a voltmeter or a test light bulb, per Jammer.

The attachment is one alternative to a test light for those unskilled in the use of such devices. There are other brands available, and similar devices are available for 50 amp, 240 Volt RV applications. I have no financial interest in any of these companies.

Some thoughts...

1. I keep one of those cheap 'outlet testers' plugged into the galley's outlet to see if our AC power is correct any time we hook up to shore power...

2. Mexico uses 60hz everywhere we've been over the years - I thought 50hz was a European thing...??

3. The DC charging feature on most small inverter type generators is only rated at about 10 Amps - using this feature will take LOTS of running time if your batteries are depleted - I use the 1.5 'rule' for recharging - if your 80 Amp Hr battery is 1/2 depleted, you'll need to 'pump' 40 amp hours back into it for a full charge; using a 10 amp chg'r, 40/10=4 (hrs) x 1.5 = 6 hours on the charger...! You'll be much better off finding a higher rated AC powered charger for quicker recharges...

3.1...Charging from your 7-way tow vehicle's system isn't much faster that the above, due to the small wire sizes that limit available charging current..this works on the road when you have hours & hours of travel but not very good for trying to recharge when you're stationary just idling your vehicle...

4. We use those power strip protectors for all our major components plugged into Ac power inside our AS - TV, Sat receiver, DVD player into one...Microwave & phone chargers into another - while 'open ground' protection may be questionable, these devices do protect your stuff from voltage surges or spikes - I've seen them 'blow' at home when we have power outages restored with BIG power spikes...

5. It's true, electronic device prices seem much higher in Mexico - You'll probably be $'s ahead to just replace your microwave & converter/charger when you get back across the border - or - the converter might have an internal 'fuse' device that's blown and would cheaper to repair...

Hope you're having fun down there, otherwise...

I have the Progressive Industries EMS-HW 30 C. This is much more than a surge protector. It monitors the incoming power as soon as you plug into the pedestal and will not allow current to flow if there are any faults with the power. High/Low voltage. High/Low current. Open Neutral. Open Ground. It also continuously monitors and will disconnect power at the first sign of trouble. Not cheap, but cheaper than a new AC or Microwave or Refer. Oh, and it's also a surge protector.

EMS-HW30C
