I have a JDM d16 sohc zc VTEC motor and whenever I push it to redline, the charging system light flickers on from 6000-6500 and then stays on solid to redline. Performance is not affected whatsoever. I have been overall my grounds and added a couple, checked them for resistance and continuity. I am also on my second reman alternator from auto zone. First one took a shit on me and this one is completely fine except for the charging system light under the conditions I described. I took it out and brought it in to be tested and it tests fine on all fronts. Any thoughts as to why I'm getting this light under load?
