Pman1961 -- the very first thing you do is make sure your battery is 100% fully charged. The electric motor in your fan pulls a good bit of current -- maybe close to 20 amps. It will pull even more if your voltage is low, and a lot of our alternators don't do a whole lot at idle. So, before you start your diagnositics, it's absolutely imperative that your battery be healthy and charged to 100% or you will get mislead.
