I am needing some guidance on what could be wrong as I have been told a multitude of issues. My daughter left her lights on and her battery died. I tried to jump it off only to realize that I reversed the polarization and put the cables on incorrectly. The fuse on the battery terminal blew so we replaced the battery terminal. The car started again and had a full charge however the IMA check engine light came on. I have also lost power to my radio and dome light in the car. I took it to O'Reilley's Auto Parts and they attempted to put a scanner on it, but the scanner would not come on to complete a diagnostic test. They said that typically is a blown fuse somewhere that causes that to happen. So therefore, we have no way of knowing what is going on. We checked all fuses in the panel and all are good but when I put a tester on some, it doesn't light up, so I pulled those fuses and they are still good and also checked behind the fuse panel for any possible burnt wiring or harnesses. I am needing some guidance on this issue from someone who has experienced something similar to this issue. Also, keep in mind that the IMA/Check engine light was never on before this happened. So, I am beginning to think that accidentally reversing the jumper cables on the battery could've been the start to my problems. Thanks in advance for any help or advice that is given!!
