I replaced battery yesterday brand new did not drive to charge it have had to get jumped several times alternator amps read almost 16 after new battery parked car sat overnight now won't start again

SOURCE: Battery wont keep charge

It seems as though the battery is feeding something that is turned on. Turn everything off in the car with the battery fully charged. Fold down the rear seat and see if the boot light is on. The problem can be found by trail and error. If you know a mate who can use a multimeter then he could do a check on the battery. If the battery is loosing its voltage, take out one fuse at a time to isolate which curcuit is drawing the power.

SOURCE: clicking starter=car not starting

the battery is located under the rear seat, check battery connections. if connections are tight replace starter.

check all the lighting on the car, IE: trunk light,glove box light, light under the hood, any small light make sure they shut off ,check to see if you have a phone charger left in the cig. lighter, radar detector ETC. any of those things can drain a battery over night quick.if you dont find anything wrong then you may have a short somewhere in the electric system... hope this helps you...

check the fuses in the POWER DISTRIBUTION BOX under the hood, There is a 75A in-line fuse and #11 - 15A fuse see if they are good.... test your alt. loom for opens, and cables .....hope this helps...GL

Perfectly normal.
Starting with the 2005 model year, light duty full size pickups and utilities are equipped with a new Regulated Voltage Control (RVC) system. This system reduces the targeted output of the generator to 12.6-13.1 volts when in "Fuel Economy Mode" to improve fuel economy. The generator may exit "Fuel Economy Mode" if additional voltage is required. This will cause the voltmeter to fluctuate between 12 and 14 volts as opposed to non-regulated systems that usually maintain a more consistent reading of 14 volts. This fluctuation with the RVC system is normal system operation and NO repairs should be attempted.
