They did a great job. I took my pickup in to find an intermediate drain on my battery. First they found that the battery that had put in a year & half ago was fried, they replaced it. The drain was still there. So they searched the electrical system more. It took days to run down the intermediate drain in the radio system. They said that they could pull the fuse for the radio and that would stop the drain, so I told them to do that and I would look into getting it fixed at a later time. It did cost me in money & truck down time. I am pleased!! They were helpful & courteous.
