Hi, I need help related to this. Six months ago I replaced battery, alternator, and VR on my '65 Dart slant. I have a new black box VR so it should have the updated, solid state "innards". The alternator replacement is the square back, but I only have the green wire, furthest from the post, connected to a tab. The center tab between the pos. post and green wire tab has no ground wire at all, but came cut to a sharp point unlike a normal tab, so I may have wrongly thought it was a delete. Should I go ahead and ground this center tab, and if so, where would be a simple/good location? Presently it idles with the multimeter showing 12.59 v with a steady, slight headlight flicker. Is it putting a slow drain on my battery by not having a ground? Thanx ahead.
