dimming clock

[ahlecks]

just want to ask kung bakit nagdidim ung clock, console light ng a/c, radio pag open ung headlight? kulang b s ground? but i already installed a grounding kit on my battery. Halos d n kc mabasa ung clock pagnakaheadlight.

Normal talaga mag-dim ang clock on most cars when the headlights are on. Pero kung sumabay na ang radyo and AC console there's something wrong na. Stock wattage pa ba headlight bulbs? Any electrical changes aside from the grounding kit?

[ahlecks]

stock headlight lng po pati stereo stock kaya ung illumination nya e pag on lng ng parklight. almost d mo n kc makita display ng clock kaya i was thinking n baka kulang p s ground.

It's night mode. It prevents the clock and dashboard lights from interfering with your vision when driving at night.

so it's perfectly normal pala coz i never experienced that before w/ my lancer, now i have a civic. tnx for the infos mga sir!

in some cars, the night mode have variable dimming control ... if your car have this feature, check it out ... baka nasa max dim position

[ahlecks]

wala nmn po cyang dimming switch, i have a 96civic vti po.

E papano po kung yung headlight ang nagdi-dim kapag nag-on yung a/c, ano po ang problema? My car is a 2008 Honda Accord with stock wattage (actually stock pa lahat ito paint, sounds, etc ). At first I thought the battery is weak already at that time so I replaced it last year per ganun pa rin. Although wala pa namang nagiging problema--- if it ain't broken don't fix it ika nga nila; I just find it unusual and since I came across this thread I might at least get some two-cents worth from the experts. Dinala ko na sa Honda pero sabi wala naman daw problema. Can any one give me an diagnosis / advice? Would appreciate it. Thanks in advance.

It's cool mode. The headlight automatically dims when you turn the aircon in order to give you that false illusion that the cabin temperature is also getting cooler

Does it stay dim or bumabalik din sa dati after the initial kick of the compressor? Noticed this even on brand new cars especially those with 1.3 engines. Pag-on ng compressor mag dim sandali lahat ng ilaw then back to normal uli.

This is also a "bug" on the Civic FD. The momentary dimming of the headlights are caused by the sudden inrush of current taking up by the two radiator/condenser fans whenever the A/C compressor engages.

These fans operate at two speeds; Low and High. Whenever the A/C compressor is engaged and/or the engine is in danger of overheating, the fans operate at high speed.

The only time the fans operate at low speed is when the engine has completely warmed up and the ECU deems it necessary to keep the engine temp within the operational/optimal temp ranges.
