Mark, at least add a fusible link to that wire... VERY bad idea just running it straight... you problem may only be that you need to replace the 100A fusible link as it is, but if you want to keep the added wiring add a 100A fusible link to it.

And BTW, incase some of you haven't investigated it before, clicking on the "Next Page" link on TEWD pages (like the one I posted earlier) usually brings up a page with collector illustration with pin numbering that matches the diagram AND troubleshooting tips.

Yea with the wires there I'm seeing about 14.2V, without it I only see like 12V which to me indicated a wiring issue.

I know I should've checked for fuses.. but for some reason, I don't have any memory inspecting the 100A fuse. lol I should go do that.
