I had the battery tested and it was good. CCA rated at 610 and checked at 610, reserve was also checked ok.
I did clean off more grounds on the car. 2 on the engine, 1 went to a spot on the r/s where the a/c lines are and another one on the firewall. Cleaned engine side also. So far on my drive to get the battery tested all seems ok, again. I will see.
