Morningstar prostar 30 load issues

I had the wiring and prostar-30 all rigged up and working perfectly for a year, today I moved the batteries outside to a new location next to the frame, all went first. I hooked up the same wiring scheme as before. Now the Prostar is not reading loads. My big concern is that I used to be able to "scroll" through the battery volts/solar amps/load amps with the push of the only button on the thing, now whenever I hit it, it jumps to Load and turns it off. Upon a restart I get the code E07, which is a Load issue. I read the instructions Morningstar has online and followed them exactly, still no luck and when I turn the van on, the volts shown in the little display (on the prostar) used to jump (instantly) to 14.1 and now they creep up and eventually reach 14.1. . Any help would be much appreciated I am heading out of town tomorrow and need it working well (first trip with new baby!!!)
Thanks for any and all suggestions in advance.

Re: Morningstar prostar 30 load issues

Some use fused shunts for metering. Not sure about your setup. I have had corrosion issues cause problems with volt/amp meters. Just a stab in the dark.
