RTGreen said:When driving at night the headlights and dashlights have started flickering. When they do, I look at my voltage..and it's charging. Is my voltage regulator going bad? Any ideas?
BTW...this is in a 72 Gran Torino, but the wiring setup should be like a mustang...I hope

Roddster67 said:Thanx, pabear. I was trying to track down that thread that had your fix in it awhile ago.
pabear89 said:Still check your Grounds and connections to make sure.

Dark Buddaha ur first diagnosis sounds exactly like my problem for 2 years now . Every night my lights go on and off for short periods of time its ****ing dangerous . Well imma try what u said about those relays and i'll hit u back. Hopefully my problem goes away.DarkBuddha said:Wow, I didn't notice how old this thread was... here are my thoughts, though a bit late...
It sounds like 2 different issues were being discussed here... Maybe separating them might help decide which one is the real culprit (unless it's both).
First, vintage Fords came with incandesant lights. Often these are swapped for halogens over the years, or when someone was looking for brighter lights. Well, halogens require more voltage to run. This often causes the fuseable circuit in the headlight switch to break, causing a flickering. As the fuseable link heats up, it breaks, the lights go out. It cools enough and reconnects, the lights go back on. The only real solution to this problem is to wire in relays for the headlights. So, how do you know if this is the issue? If the lights are ok initially, but over time begin to flicker, getting progressively worse and off for longer periods of time, then this is probaby your problem.
The second issue is related to a bad voltage regulator, bad alternator, or poor ground. I lump all of these together because the symptoms are probably pretty similar. Brightening and dimming from the moment (or shortly after) you turn on the lights. This won't typically be outright flickering, but more a dimming and brightening.
Hey, maybe dragging up an old thread can be helpful... Yep, this problem is a very common. I suffered with it for a couple years before I finally found out what it was (that was before the internet). I don't know if you caught it, but you might check this site which was referenced in a previous post: http://www.midnightdsigns.com/james/headlights.htmBIGJUNE said:Dark Buddaha ur first diagnosis sounds exactly like my problem for 2 years now .
