Hello - Thank you! so i originally tried starting the car immediately after i took it off the tender. I waited a day then tried again and she started right up.Given the history and observations you presented, my first step would be to check the battery voltage...but do so after it has been off of a charger or tender at least 30 minutes. After noting that reading and with the volt meter still connected, turn on the headlights to see the effects of a load. Please report your findings.
I have not checked the battery voltage yet, but i am curious so i will test that and see what happens when i turn headlights on.
