Stop in for a cup of coffee

So, got my truck running, wifes suv also started. Plugged in for 6 hours. My plow truck was running so bad yesterday i couldnt plow. Aux battery had dirty battery connections and i think it was arcing. Drove the computer nuts. All i did was clean posts and cables and charge it. Runs like it did last summer. And plow pump works a ton better.
