Okay, so I'm new to the forum but not new to Hondas or working on cars in general. I have a 2000 EX, 5 speed I just purchased a week ago. It has 189k Miles and looks like it only has 30k and everything is stock except for one new OEM motor mount (practically a damned unicorn these days). So onto the meat of the subject, driving at night from work, my instrument cluster lights, including the cruise light while it is on, as well as the headlights will all flicker/pulsate in no discernible pattern while cruising on the interstate at or above 3k rpm. It will sometimes get bad enough that the SRS light will come on intermittently. No CEL has been thrown (and yes the light does illuminate during KOEO check). Battery light does not come on during driving either. I plan to test the battery and clean up the grounds and check all major power connections for tightness this weekend. I just wanted to see if anyone has ever found a definitive fix for this condition? All the searching I did came up with alternator, battery, Fuse #15 and some wiring harness woes under the intake, but no one ever finishes their damned posts if they fix it or not!!! So if anyone has some real knowledge on remedies of this condition I would really appreciate it! Thanks in advance.
