I'm trying to troubleshoot an ongoing problem with my sister's 99 Elantra. I had to replace the negative terminal back with andaftermarket one in Jan as the terminal was corroded and loose to the point that it would not stay on the battery terminal. This was giving the symptoms of the radio going out and lights dimming. Well the symptoms have come back, but this time she mentioned that it was happening when she was pressing the brakes. So I first checked the terminals and found a lot of corrosion on the terminals. The screw on the negative one which I replaced in Jan looks like it has been rusted for years, but all terminals are tight. I did take the car for a test drive and of course it didn't happen. From my experiences on Hondas, the amount of corrosion dust that is appearing is unusually high. Is this typical of Hyundai's? Both Hyundai batteries have been producing the residue but it has been happening worse as the car has been aging. Any help would be appreciated.
