Ok, I'm tapping into your minds. I'm working on getting the TT ready for summer. I pulled my battery last fall and stored in my garage. I ran a battery tender on it. I got the TT out of storage a week ago and sat the battery on it. It's been below 20 a couple times, but nothing drastic. So today I hooked it up and it wouldn't run my jacks or lights. Voltmeter read 12.66 . Any ideas? Let me know.
