I've been struggling with this issue for about two years now. Off and on between work other projects it's became frustrating and getting pushed to the back burner, but I'm ready to solve it. I have a 1968 mustang. Long story but the car over the past couple years started to lose things such as at first brake lights and runnings lights. Then the headlights started to flicker eventually they quit working. Then my brake lights went out soon thereafter.
I've replaced almost every thing I can think of. Alternator, voltage regulator, headlight switch, dimmer switch, brake light switch, fuses. I can't tell you how many headlight switches I've swapped. I did some more research and I thought maybe I need to have another ground off my battery to the engine bay so I did. Still no avail. I'll have a video of what it is doing. Really does have me stumped, but I'm more than ready to figure it out.
Also I'm not sure what the black wire is for? I thought a ground but when I try to ground it it shoots sparks.
Thanks for any help
Ben
