Q: Car is suffering a voltage failure
My car is having some sort of voltage failure. My car is very easy to start with a jump or portable battery, and then I will have no problems for about 24 hours. I took the battery to be tested and it is showing as okay, though they said there might be some type of minor voltage problem.
