Bad ground?

The car can start now, but the car is still acting like the battery cables are loose. The battery is 590 cranking amps and is holding a good charge. I have not found another cable that goes from the starter to the frame but there is a small wire or cable that goes to the fire wall? The ground to frame on the Neg. is good.

OK well you did not answer the question

What does "acting like" mean?

Does the solenoid buzz? It just turns slow? Does it turn slow with ignition on and off both?

DO YOU HAVE a multimeter or at least a test lamp? Clip leads?
