Here's my final findings.
1st, there is NOT a short between the yel/wht wire that powers my main relay. That has good continuity. So, next i back tracked to the fuse box. Well, no volts there either...
Just to make sure i wasnt fooling myself somehow, i poked all the other plugs/connectors in the box, and sure enough all the other ones showed ~12.5Volts. But the one prong that actually lets power feed back to my main relay is dead with 0.00Volts.
Is it the actual fuse BOX itself that id go about replacing at this point??
