There is power to it and the fuse itself is good, but none of the interior fuses fed by it have any power.

Hi,

It sounds like you have an open circuit between the two. I have a question. I realize the fuse is good and there is power to it. However, have you confirmed there is power out from the fuse? Have you checked the fuse for continuity? It may appear good but have an open you can't see.

I attached a pic from the schematic and highlighted the fuse I believe you are referring to. Please confirm that for me. Note it is a fusible link, so this isn't a traditional blade-type fuse. So please let me know if you have power to and from it. If you do, at the interior box, locate the solid white wire and check if there is power to it.

Let me know.

Joe

Yes, that's the one. Yes, I checked, and it has continuity. Is there a relay inside that the white wire goes to then out to fuses? If so, how do I get to it?
