Just grab a multimeter, and check it (they cost less than $10 if you dont have one already)

Sounds like the brushes in the alternator may be worn down so far they are only just touching the slip rings - an easy check by removing the brush holder at the rear of the alt. (2 screws). If not this I'd be looking at switches, relays and fuses.....move each of these to see if it causes dimming. I'd agree with the above posts as well.

My VS's lighting and head lights dim on start up, but I imagine this is because the starter motor draws alot of power from the battery temporarily cutting back the power for other accessories, I think its fairly normal.

ok update..

battery is ok (got it tested)

alternator output is 14.6 volts (when it diming up and down)

its liek its arching somewhere and makeing the lights, intrerior light, dash lights dim/spike (if that makes sence)..it only does it if it has been sitting (un started) for more then 4 hours...then it come good when u drive....but does look funny when u driveing and light are diming up and down (and interior lol)


seems liek it getting worse to:(

is there a main wire running somewhere that can cause this? me dad is an electrition and is handy with automotive sides of things but if we/he cant find anything then ill bite teh bullet and take it in it a auto place:(


yes i have a sterio in teh car but it aint on when i start it
