So I'm having problems with my 1998 s70. I've replaced the alternator and battery already but it seems to still have electrical problems. The car will shut off (all lights, radio, everything ) without warning. I found some corrosion on positive terminal and cleaned it off. It seemed to run fine for a couple days, but then it started again. No check engine lights nothing. There's typically no jerking or anything before it shuts off so I don't know when it will. Any ideas??
