My name is ***** ***** I will assist you with your question today.

I'm an independent contractor and I don't get paid until a rating has been made.

We can go back and forth as needed to help resolve the issue you are having. Follow ups are free after ratings, so rate in confidence!

I just want to understand correctly. You have power to the fuse box, but lose power after? Have you tried jumping the fuse location to rule out the fuse pins not connectiing well to the fuse? What about the relay? The relay feeds the fuse, not the other way around on this year. I have the diagram is you need it.


You want a 5 star service and I want to provide a 5 star service. Please consider that I don't know your skill level as well as I can't see, touch, smell, hear the vehicle/machine in question. Please provide as much detail as possible and I will provide as much back.

Once an answer is provided, you should see a rating screen. Please rate my personal service to you. The ratings are my personal feedback, they are not the site feedback.
