Hi guys. I've been vibrating in my seat waiting to learn the solution, but I see you've been wasting a lot of fuses. Please allow me to add my trick that will solve that. Use a light bulb in place of that fuse. All that will happen is when the short is present and the circuit is powered up, the bulb will be full, normal brightness. It will get hot so be careful where it's laid, and it will limit current to a safe value. My drawings show using a common 3157 brake light bulb. That will allow up to one amp to flow. Once the short is removed, the bulb will get dim or go out and the circuit will resume trying to work. If the bulb limits current too much, you can use a head lamp bulb instead. That will allow up to five or six amps to flow.
While this works great for fuses, I'm posting the procedure for bypassing a relay instead. I see a lot of mention of that. By bypassing the relay instead of the fuse, you usually can power the circuit without needing to turn on the ignition switch or do anything needed for that relay to turn on. I made these drawings over-simplified, but that's easier than trying to describe what to do. You do have to install a good fuse.
Joe can elaborate on where to find the items I listed, and which relay terminals to use if yours look different than those in the drawings. You can do this just as easily at the fuse socket too if you prefer. I hope this will help you guys figure this out.
