Three days ago, I started work at 5 am, and at 5:30 am my office got a call. It was about my trailer I was pulling, it had no running lights. I did not even notice, because when I started out all the lights were working. So after I dumped the trash, I looked at the obvious things, like the plug. That looked good, and all the other lights worked, so it must be a fuse or a relay. Yaaaaaa, if any one has dealt with fuse issues before, they can be tricky.
Not having the owners manual, I googled it with no success on the first try. So I had dinner, and then hit the books again, or the modern day books, the internet. Found this awesome site.https://www.startmycar.com/ford/f-150/info/fusebox/2009?gclid=Cj0KCQiAkZHTBRCBARIsAMbXLhE2TZXEkoe_tvd-BHeczVqQXVozByyVqzu6BUqg2JyFNJFz1su1sPYaArwFEALw_wcB#anchorfusebox1 This is for my truck, but it has a interactive fuse box. So I wrote down all the relays and fuses and went and checked them. Boom found a 20 amp fuse that was blown, and now all the lights work. This was possible the fastest electrical problem I have fixed. I did this all while the Vikings were getting blown out.
