Hi. For over a month the light has been on. (No error codes as seen with (legacy OBDII) ScanGaugeII. Do others have to live with it on? Is it only a cosmetic issue as I have suspected? Besides the dealer, is there a way to dump a numerical code? I read a post suggesting that dumping more than 14 amps onto the HV "bus" will generate a code. I have been using the 3000W converter for all this time.
