thanks for letting me come into this group. i love monte carlo ss and have owned several through the years but had to sell due to divorce and other things. my son currently has a 86 ss and all the lights go bright and dim inside and out and only his low beams will work. i pull wire from alternator and it stops and i have replaced it as well and also replaced dimmer switch but still no luck. any suggestions as im lost when it comes to electrical. thanks again
