Something is still wrong with the charging system. Should take it in to be looked at.

No but i am going to check them out tomorrow also checking grounds. Can you do a continuity test on a battery cable?

Yes you can. Have your digital multi meter set to the ohms Ω position. Check from each end of the cable, the readings should be 00.000. Also check at the battery terminals when the engine is running to see what kind of DCV are going to the battery. There should be from 13.8 to 14.7 DCV at the battery if the alternator is working properly. Rev the engine up also when checking this. If it was over charging it would show up revving the engine up. With the engine off the battery should check 12.5 to 12.7 DCV indicating it is fully charged.
