Audi Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
Can you please explain what relay switch you are looking for. There is no relay that will cause the complete system to be dead. Are you sure the battery is fully charged and the cables are clean and tight? Let me know and we can work from there.
Okay so what relay switch are you looking for?
All main power comes from the main fuse link (150 amp) located in the power wire coming from the battery to the under hood fuse panel. Are all your fuse dead under the hood in the panel?
Okay then start with checking to see if you have power (key on) at all the fuses in the under hood fuse pane and if not then check the fuse link in the power wire in the harness from the battery to the fuse panel.
