Greetings gents, Fairly recently I replaced the alternator on my 1955 Willy’s utility truck with the I6. The old alternator was whining when I got the truck. I’ve noticed that this new one doesn’t seem to be charging the battery at all. When I try to test it with a DMM it something interferes with my multimeter when I get close to the alternator. Even with the probes unplugged I get a reading that jumps all over the place so I’ve been unable to test it. Could this be another bad alternator or a bad ground wire somewhere? This is my first project vehicle so I’m pretty new but I’ve always been interested in restoring an old jeep. Any suggestions are appreciated!
