Hello forum. Got a no start issue on a 2001 2.7. All of a sudden the car just clicks!!! Checked voltages at battery and when running at alternator and all meters correct. I found corrosion at the positive side terminal And cleaned it , and then it started!! Fine for a month then it did it again!!!! So i had it towed home and installed a new battery, it started fine for a week and then today , it did it again!!!!! Brand new battery meters 12.85 volts. But it just click, click , clicks!!!!! Any thoughts???? Thanks.
