I've had my deceased Uncle's 68 300 for about 20 years. I guess you could call it survivor type car although he managed to bang it up a couple of times before he passed on. Anyway here's the question. Last year when I had it out for the summer I noticed the alternator gauge would flicker over to discharge occasionally. This summer I got it out and it is sitting on discharge constantly. When you apply any accessory that uses power it drags further over into the discharge zone. I've changed the alternator and checked the ground off the battery and all seems fine with that. I much more familiar with 70 Mopars and I don't even see what appears to be a voltage regulator under the hood of this 68 C-body. Anyone have any ideas what I should try or check to solve this problem? Electrical is far from my strong point!
