Default Re: Don't Blow Your Battery Tender

I think you may have had a bad unit. There has to be protection for high amp draws. They put out like a 1/a and that is it. Generator current should go to the battery before the tender because that is the path of least resistance. It is a good idea to unplug it first because you do not want to drive off with it plugged in.
