There is ONE way to find where current is going. You can ask for "ideas', you can guess, you can search youtube videos - or you can do the ONE thing that will give you your answer: remove the battery ground cable from the battery post, insert an ammeter, and start yanking connections until you find where the current is going. You will need the diagrams in the service manual as well.

But no one wants to hear it, so I will stand down while others toss guesses at you.
