TURBO200R4
stand up straight and grab the world by the a$$
Why would you say that ? It is putting out 13v AND it is only weeks old? Could the charger be the issue, you think?
Well u have charged it up to over 13 volts so your charger seems to work
So that narrows it down to either bat or cables take tour pick. I would put my money on a defective battery.
I am curious when u stopped trying to start did the volts come back up to the 13 ?
