The alternator sounds like its got a slight hu and the PRDL lights flicker. Tonight the warning lights all went off and on the gas gauge drops to empty . Headlamps were not noticeably affected --- vehicle kept running but lights on dash go on and off.

Hello,

This sounds like you could have a problem with Ground 201. In the diagrams down below I have included a wiring diagram of your vehicle's instrument cluster with the ground wire and ground highlighted for you, and a description of where Ground 201 is located in your vehicle. I have also included a guide on how to inspect grounds for you in the diagrams down below as well. Please go through these guides, inspect Ground 201 and get back to us with what you are able to find out.

Thanks,
Alex

I found this morning everything was dead. No start, no lights. Upon a short inspection I found the positive battery cable to be loose. I secured both cables and have not had a problem since. Thank you for your input.
