We just bought our first "hard sided" trailer, (we had pop ups for 25+ years), a new 2010 Outback 230RS. My question is about charging the batteries, and generators. We dry camp, and bought 2 Honda 2000 generators, the i, and its companion generator for when we need the air conditioner. Our 1 month old 2000i quit generating 120 VAC, but still puts out the DC, so it is now in for warranty repair. My process to charge the batteries, and run the microwave, etc. was to start the generator totally unplugged, wait a min. for it to warm up, then plug in the Honda Accessory. DC battery charging cord connected to the batteries into the generator, then plug in the 120 AC cord from the trailer into the generator. The DC battery charge cord out of the Honda will put out 8 amps when the generator is off its energy save mode, and rev'ed up. Every time I would plug in the 120 AC cord to the trailer, into the generator, (at the slower RPM / energy save mode "on", everything turned off), it would make a spark at the ac plug.

So my questions are:

How many amps will the trailer inverter put out to charge the batteries?
(I was told it was just a trickle / float charger by the dealer).

Am I creating some kind of short / feedback loop by putting the 8 amp output DC Honda gen. accessory cord on, AND plugging in the trailer 120vac cord in at the same time?

Is the spark normal when you plug in the 120vac? Nothing is turned on in the trailer when it is plugged in.
(The dealer checked the trailer out, after the generator failure and said it was all fine).

I read the inverter manual, but it says nothing about amperage output, just voltage. I want to get the batteries charged as fast as possible so as not to run the generator any longer than i have to. Am I doing something wrong, or did the generator just have a problem???

Thank You for any help.
