Have an 08 with roughly 320k miles on it, 12v battery got jumped wrong and fried the system. ive already replaced 2 small fuses and the 100A fusable link, all of them visibly blown. Car went from completely dead to actually firing up, but the ICE will not stay running. It shuts off quickly and while it is running shows that its not charing at all on the screen. Is the inverter the culprit, or is there anything else i can look ar first.
