KarenLukens Posted March 15, 2017 Share Posted March 15, 2017 I plugged the tester into my car and I'm getting 12vdc out of it to the trailer, but I don't think that the trailer is charging from the car when towing. Is this normal? Do I have a fuse to reset somewhere? What do I do to test the trailer charging system from the car? With the Solar it really hasn't been noticable except for on one cloudy rain filled day that we were driving. After a full 6 hours of driving, the trailer charge level had only moved 1/10 on the Zamp meter. I realize that the Zamp meter isn't designed for this but I'd like to check the battery charging connection on the trailer if possible. I have a multimeter and a test light probe with me.
