My first post: Just acquired an 07 RR Sport HSE with the 4.4L Jag engine. Runs fine but, lots of lights on the dash. The radio has no power nor the main info display. Former owner said its probably fuses. Also when i start it, nothing is working on the dash. after a few minutes, the gages will work, oil light on , check engine light on, brake light, tire pressure, ride adjustment all on. Then the dash goes dead again. Any thoughts? Thanks so much.
