Needs some advice please! Does anyone know the proper procedure for using the red ZIVAN battery tender? Reason I ask is that when connected to the car's cable, it continues to have a solid RED light and flashing GREEN and YELLOW. The manual states there may be a short somewhere, which I assume is a blown fuse. Can someone tell me if (for the F models with a plug in cable) there is a fuse between where the tender is connected and the battery? I know there is an internal fuse in the tender, but I kinda doubt that is the cause. Anyway, all help appreciated as I don't want to cause damage. Thanks
