Voltage problem
Thank you so much for all the information I’m going to do that this weekend coming up, I got the star lock washers and got my VR grounded better and the ALT gauge isn’t going crazy anymore. Thank you!!YES and I mentioned that above. VR MUST be grounded to "same as battery" Scrape around the bolt holes and use star lock washers. IT is wise to add a ground cable from engine block to body
Not sure on a 6 where a good handy spot is, but a great body ground is to bolt the cable to one of the master cylinder mounting studs. Buy what is called a starter cable, "eyelet to eyelet" ends and they come different lengths
