So when I got it the my charging ports didn't work blew every fuse almost instantly and mph gauges/instrument cluster would periodically flash jus thought the bulb was going out.. one day turned on map light and it started pulsating to the music i was listening to along with the instrument lights come to find out the overhead map light cluster the little red accent lights were melting the board so I just took the whole board out (sucks to have no interior lights) thinking it would fix issue the gauges it still flashes an my battery has been losing voltage any ideas on how to find issue appreciate all imput
