Sometimes when I hit the slam button, my battery amps drop and stay around 8. I have power, but not enough to even click. Jump starts dont help. I replace the battery and all is fine. Ive gone through 4 in the past year. Those four were 310cca from Advance Auto. I believe it was the batteries. I purchased todays battery and was told by the motorcycle shop owner that I need to ground to the frame also. He said the battery couldnt handle the load. Two ground lines? I fail to see how that would help.
