Re: 68 chevelleTail light issues
GM, in their effort to save money, uses the chassis as a common ground. This means there is one less wire to everything that can be grounded through the chassis. Pay particular attention to how the light fixture creates a ground. One real easy thing to do is get a scrap of wire and touch it to ground on one end and the light fixture on the other. It will likely clear up the issue.
People donít like to have to think in high resolution. Jordan Peterson. Thatís why we are forced in to so many binary choices.
