1995 200sx SER. Had bad alternator, replaced alternator, now battery and brake light on (bright no dimming or flickering) battery 11.9 after sitting 2 weeks) 14.9 to battery running, 14.7 with lights, fans, radio on. lights dont dim or even flicker. 15.2 on battery cable from alternator disconnected from battery. car will run all lights and fans without battery hooked up (no issue) Cleaned and sanded grounds, battery cables are good. any particular shorting or bad grounding spot anyone has found?? voltage regulater sending bad info to ECM? stumped. I guess I can replace new alternator as I know sometimes they are bad, but this one seems to be working so I am at a loss?????
