Put new starter on and the same thing. Hooked my charger up to battery and it reads a full charge. Any ideas why it seems to take the extra juice to kick it over? Or could the battery just be holding enough to run lights and such but not turn over the motor? Battery is 6-7 years old, maybe a little more.
sounds like a bad cell in the bat. 6-7 yrs old says a lot.
