Fix your Dewalt 20V MAX Li tools!! Easy fix for intermittent problem.

I show you a common problem on the Dewalt 20V lithium tools and how it can be fixed. In this video after opening the tool I found the tool was still OK and the battery was the culprit, but I show you the trouble area to look for. The symptoms are: tool cuts out intermittently, functions better in one position and not another, and the LED worklight will flash.
