Wires To Alternator Help

You should see around 13.5v to 14.4v while the engine is running; Measure it at the battery and at the alt and reference ground at both the battery and the at the chassis. A low reading at the battery but an acceptable reading at the alternator indicates a bad battery wire or fusible link.

Mark, at least add a fusible link to that wire... VERY bad idea just running it straight... your 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.
