I am baffled. Replace the rocker switch to the wipers today. All hooked up ok, no issues and wipers work. But.......there is an in-line fuse that comes off the back of the switch panel and goes to the wipers that keeps blowing. However, everything seems to be working, I can't find anything that isn't. If I take the fuse out, the wipers still work. All other electrical devices work on the boat too. I am at a loss as to what is shorted and why everything still works eventhough the fuse is blown.
