The factory ammeter in my dash has never worked properly, so a few months ago when I was replacing the dash bezel, I just didn't hook it back up. I was reading an article about after market guages in the tech references section of this great web site and it mentions that the ammeter actually completes the circut for the alternator to properly regulate the voltage in the electrical system. Did I read that article correctly? Am I screwing up the ability of the alternator to function properly by not having the ammeter wired up? I have been having problems with the system charging properly, but didn't think that this was related until I read that article. If anyone knows, I would really appreaciate a reply. As you can tell, I am not any kind of a wiz at electrical problems.
