2012 jeep cherokee v6 have installed new alternator and new battery but am only 10dcv at battery terminals

SOURCE: 95 jeep grand cherokee laredo

the best way to look at this problem is with a12 volt test light then remove the ground cable from the battery turn every thing off inside the car close all doors and remove keys then connect testlight to battery cable and touch the test light point probe to the negitive battery post if test light lights up for more than three seconds and stays on you have draw on the system. dont panic it maybe just a glove box light or door switch. if suspect a circuit simply un hook it retest again .if you open a door that will make light test come on recheck all doors closed. if you still have test light on locate fuse box and remove one fuse at a time until test goes out while holding door switch in.when locate circut use wiring diagram to assist from ther. if the light does not light up check altenator output volt meter shoud be 13.2 -15.5 volts when running.

The heater-A/C housing assembly must be removed from the vehicle and the two halves of the housing separated for service access of the heater core, evaporator coil, blend-air door, and each of the various mode control doors.

WARNING: On vehicles equipped with airbags, refer to Airbag Systems Safety Information and Procedures. Before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Failure to take the proper precautions could result in accidental airbag deployment and possible personal injury. See: Restraint Systems\Air Bag Systems\Service Precautions

   3. Remove the heater-A/C housing from the vehicle.
   INSTALLATION
   
   1. Position the heater-A/C housing to the dash panel. Be certain that the evaporator condensate drain tube and the housing mounting studs are inserted into their correct mounting holes.
   2. Install and tighten the five nuts onto the heater-A/C housing mounting studs on the engine compartment side of the dash panel. Tighten the nuts to 6.2 Nm (55 in. lbs.) .
   3. If the evaporation canister was repositioned during the removal procedure, reinstall it to its proper position.
   4. Connect the Heater-A/C system vacuum supply line connector to the tee fitting near the heater core tubes.
   5. Unplug or remove the tape from the heater core tubes. Connect the heater hoses to the heater core tubes and fill the engine cooling system.
   6. If the vehicle is not equipped with air conditioning, go to Step 10. If the vehicle is equipped with air conditioning, unplug or remove the tape from the accumulator inlet tube and the evaporator outlet tube fittings. Connect the accumulator inlet tube coupler to the evaporator outlet tube.
   7. Unplug or remove the tape from the liquid line and the evaporator inlet tube fittings. Connect the liquid line coupler to the evaporator inlet tube.
   8. Evacuate the refrigerant system. Refer to: Heating and Air Conditioning, Service and Repair, Procedures, Refrigerant System Evacuate, See: Service and Repair\Refrigerant System Evacuate
   9. Charge the refrigerant system. Refer to: Heating and Air Conditioning, Service and Repair, Procedures, Refrigerant System Charge, See: Service and Repair\Refrigerant System Charge
   10. Install the instrument panel in the vehicle. Refer to: Body and Frame, Interior Trim, Dashboard / Instrument Panel, Service and Repair, Instrument Panel Service Procedures, Instrument Panel Assembly Replacement, See: Body and Frame\Interior Moulding / Trim\Dashboard / Instrument Panel\Service and Repair\Instrument Panel Assembly
   11. Connect the battery negative cable.
   12. Start the engine and check for proper operation of the heating and air conditioning systems.

1. Remove and disassemble the heater-A/C housing. Refer to: Heating and Air Conditioning, Housing Assembly HVAC, Service and Repair, See: Heating and Air Conditioning\Housing Assembly HVAC\Service and Repair
2. Lift the heater core out of the lower half of the heater-A/C housing.
3. Reverse the removal procedures to install. Be certain that the heater core foam insulator is reinstalled

SOURCE: How do you change a 2000 Jeep Cherokee alternator?

i did this, its a pain. First disconnect your battery. Then loosen the tension pully - there are two long screws on the top of your engine - they go thru something, i cant remember what, then use a screw driver to pry it back and pull the belt off your alternator. As for the alternator itself - you have to climb underneath the car to get it out, and there's not much room for hands - if i remember correctly there are 2 or 3 bolts on it. once your drop it down there is a strange wire clip you need to unplug. Call around for alternator prices, i was quoted from 169 to 305. If you got the dough take it in - of the 4 cars ive put alternators in this one was by far the worst.

How to Replace an Alternator (DIY Time: 2.5 hours)
Complexity: Moderate

Parts:
1. Alternator - $151.95

Tools:
1. Combination Wrench Set
2. Screwdriver
3. Multimeter
4. Serpentine Belt Tool
5. 3/8 in. Drive Ratchet
6. Socket Set

Steps:
Step 1 Open the hood and locate your vehicle’s alternator.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.
o Tip: Always make sure the struts on the hood can fully support the weight of the hood so that it does not close on you while working. The use of a hood prop can securely hold it in place.

Step 2 Using your digital multi-meter, check the battery voltage. A dead battery will usually have less than 9 volts. This would not be enough power to start most vehicles.

Step 3 To verify that your alternator is bad, make sure your battery is fully charged and can pass a load test.

Step 4 With the good battery installed, connect your digital multi-meter across the battery terminals with the engine turned off. A good battery should read between 12-13 volts.

Step 5 Start your engine and read the digital multi-meter’s output. The voltage should rise near 13.5-14.5 volts.

Step 6 Using an open end wrench, disconnect the battery’s negative cable.
o Tip: When disconnecting battery cables, be sure to always disconnect the negative cable first and do not allow it to come in contact with the negative terminal post while working on the vehicle.
o Tip: Wrap the battery cable with a shop towel and pull it away from the battery terminal.

Step 7 Disconnect the power and ground wires on the back of the alternator paying close attention to where each wire connects. Disconnect the wiring harness connector.
o Tip: Check for a loose wiring harness connector, cracked wire insulation, and corroded terminals. Replacing the wiring harness may be necessary.

Step 8 Loosen the alternator bracket bolts, and alternator adjusting bolts or alternator belt tensioner so that you can remove the alternator drive belt.

Step 9 Using the proper size socket and ratchet, remove the alternator mounting bolts, spacer (if equipped), adjusting bolt, lower pivot bolt (if equipped), and the alternator.

Step 10 Install new alternator.

Step 11 Using the proper size socket and ratchet, loosely install the alternator mounting bolts, spacer (if equipped), adjusting bolt and lower pivot bolt (if equipped).

Step 12 Install the alternator belt.
o Tip: When installing the alternator belt, make sure the alternator belt is fully seated in the groove of the pulleys.

Step 13 Pull the alternator until the alternator belt is tight.

Step 14 Tighten the alternator mounting bolts while gently moving the alternator unit to achieve proper alternator belt tension.

Step 15 Reinstall the power and ground wires to alternator. Install the wiring harness connector.

Step 16 Push down in the middle of the alternator belt to check belt tension. If the alternator belt moves more than a half an inch, it is too loose, adjust the alternator belt to proper tension before proceeding to next step.

Step 17 Now that the alternator belt has been installed and adjusted, reconnect the negative battery cable. Start the engine and check the battery voltage to verify proper alternator charging.

Step 18 Turn off the engine and recheck the alternator belt tension. Readjust the alternator belt tension if needed.


Good luck (remember comment and rated this).

Hi. A single click from under the hood on an attempted start could mean a bad starter relay. You may want to test the battery also if there is a charge. Might be the car is not charging the battery.
