Question about Ford F-450
Yes. Depending on the Coach company there may have been an inadvertent error. The lighter is a simple positive/negative connection. Even if the leads are reversed the lighter will still work. If overloaded then the fuse will blow. To check to see if the polarity has been reversed: use a test light to determine the polarity. The center down inside of the lighter should be the positive. The side walls should be the negative. I hope that helps, if so, please rate my assistance and leave a testimonial.
