Here’s the background: After recently leaving my tc parked for too long, I returned to find the battery dead. A young fellow tried to help me jump my car, but he had mixed up the positive and negative cables for several seconds before I was able to remove the clamps.
After that afternoon, I was eventually able to get the car to start with a new battery, but the OBD2 reader gave a p2118… I found my ETCS fuse was blown and replaced it which seems to have resolved that part of the problem. Now I’ve noticed my radio won’t turn on. The radio fuse is dead too, and replacements instantly spark out and die when inserted. Does that mean that there’s a short somewhere in my electrical system? Is the car safe to keep driving and keep connected to the battery? I hadn’t noticed the problem with the radio for several hours, are there any other non-obvious components that I should check for damage?
