Ok Don in the past I have dealt with a blown disable link on customers boats that they have caused. In this case I installed a new 250 on a friends ranger last week and out of the box had a charging problem. Turns out the link is blown or bad in some way not allowing the charge to pass. Have you ever seen one blown or have a manufacturer defect out of the box? And am I pissing in the wind trying to get it warranty replaced? Sn 2B575706 thanks
