I want to thank all that answered the question about how to install the ammeter and their thoughts. What has troubled me is that you would think as triedaq states, “that the alternator would never run at 85 amperes”. I thought that running a number 14 strained wire would be just great, but I have read articles that say you must match the alternator output to the wire size. To old school you are right a volt meter gives more information than an ammeter without the worry of setting your car on fire. This is my first time on a discussion group and you guys are great. Thanks, if you have any additional info please let me know.
