Easy way to measure solar output (Amps)?
I tried measuring the circuit between my solar panel and the controller today, but couldn't get a reading. I was wondering, should a digital multimeter (I have a Fluke 115) be able to read small amou...

I still don't understand why I get such strange readings when I detach one cable from the battery and place the multimeter in line, one probe on cable and other probe on battery terminal. The digital display shows wildly changing numbers, starting at maybe 2+A and quickly descending until it reads almost nothing.
Since My controller plugs into the trailer's pigtail, I'm wondering if the TT converter comes into play in this? Maybe someone can tell me, when I drive down the road with the pigtail plugged into the TV is my TV charging the battery directly? Or only indirectly, through some governance of the converter? If the latter, maybe I would be much better served by rigging up something going directly from the solar controller to the battery terminals. Maybe the on-board converter is greatly reducing the amount of current reaching the battery from solar via pigtail.
I have found that the voltage in the TT interior (it has a cigarette-lighter style receptacle that I can easily check) runs as high as 14.3V during the midday charging, so that led me to believe that the converter is not reducing what the solar controller puts out.
