I did not as I was getting it ready for winter storage. It's been on the tender ever since and have not heard it. But I feel confident if I took it off the tender for several days they noise will come back. I ran it for codes and there wasn't any of concern. Not sure how it's linked to battery voltage ,but if it's only reproducible under those circumstances I'm not worried about it being a valvetronic issue
