Hello and Thank you for choosing Just Answer.
Before I can help you, I will need to know:
Thanks for your response. I just looked at the receipt for the battery test results and it says Good Battery Voltage 12.55V Measured 725CCS Rated 700CCA temp 42 degrees F and as I stated earlier, I didn't turn on the truck as the women indicated it wasn't necessary. I guess my question would be what would cause the alternator to go out in less than a year? Also, what is an instrument cluster? Will it be costly to replace?
