Low voltage even after new alt and new batteries.

battery charging problem.
Alright. So about a year ago I had a edge evo ht fry my ECM. I have been reluctant to add a tuner again after that but I purchased an edge ez today. Truck had new alt installed 500 miles ago btw. So I installed the new tuner and now I have low voltage and check guages light. Put new batteries in today due to a failed load test. Didn't fix it. The Main alternator fuse isn't blown and the terminals that run to the fuze arnt getting any voltage. Batteries read 12.5 when trucks off. They read 10.5 when running. I'm very concerned this stupid edge is causing problems again. Any I ideas?
