Quick and easyOne of the first tools I use to verify circuit integrity. Nothing replaces a good meter, but tools like this save you time in the diagnostic process. Works perfect for checking fans and useful when needing to the bump starter. Any tool that turns a two man job into a one man show is worth it's weight in gold.
