I have a 98 Civic LX-EJ6 stock D16Y7 engine. Battery indicator stays constantly dim when car runs and only started when I swapped out all the stock cluster lights for LEDs - the damn battery charge light was blown previously and I didn't notice it.

No dim or flickering lights, wipers etc.
No problem with weak battery or starting car.
No fuse 15 problems.
Alt. belt is tight.
Alt w/ new belt & battery installed December 2013. Battery new, alt probably reman (installed by my trusted garage mechanics on 12/09/2013 battery was put in about 24 hrs earlier)

Voltage test run with ANALOG multimeter:
car off ~12.5v
car running ~14.25-14.5v
car running with brights, ac on/fan high,aftermarket fogs on,aftermarket stereo, and accessory plug in use ~ 14.5-14.75v

Took car to Advanced Auto 3-4 days ago when I first noticed it and had them test the charging system, battery, starter, and any parasitic drain. All were good so they said.

Pulled 4 pin (GREEN COLORED) alt connector with car OFF after multimeter tests & turned ignition from OFF to ON(II) [engine off]. Light does not come on.

Any ideas or do I need to see about replacing the alt yet again?

EDIT: Fixed a few idiot typos on my part and updated with actual date of alt installation after finding the service receipt.

 

The LED is the problem.

 

Defective LED or is it just b/c LEDs take less voltage to illuminate and there is constant voltage going to that light?

 

I believe what Ron Burgandy is saying is the LED is at fault because there could be a live ground wire tapping into that particular led and causing it to come on.

 

You cannot use LEDs for all of your cluster bulbs. You can only use them for the illumination bulbs.

 

Dammit thanks... time to undo that then.
