Why is fully-charged battery too low to start within 6 hours?

It is not impossible for new batteries to be at fault , check with high discharge tester, if OK there is a short circuit or something using up power such as stop lights on. to check remove the + terminal on the battery insert a amp meter current draw should be almost zero , small current draw will be from clock ECT.

My truck battery is going dead n i have tested n discovered that it is through the oxegen sensor wiring. i have unplugged all three sensors n still have the drain. any ideas what to do next?

have you had a load test done on the battery. batteries die in cold weather. If it is going flat after disconnecting the sensors then obviously that was not the fault. If the battery proves good disconnect the earth wire to the battery ,put an amp meter in the circuit and get an idea of the current flow . That will give you an idea of the size of the unit drawing power.

What is the PO320 code? what is wrong with my 2005 Hyundai xg350L?

P0320 Hyundai Ignition/Distributor Engine Speed Input Circuit Possible causes
- Faulty Ignition/Distributor engine speed sensor
- Faulty Crankshaft Position sensor
- Ignition/Distributor engine speed sensor harness is open or shorted
- Ignition/Distributor engine speed sensor circuit poor electrical connection
- Low battery charge
- Faulty Engine Control Module (ECM)
What about the obd code?
The P0320 Hyundai code is triggered when the Engine Control Module (ECM) detects that there is no current at the ignition coil group
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- The engine may be harder to start
- The engine may stumble or stall
P0320 Hyundai Description
Ignition failure sensor is used to check whether the spark ignition is occurred correctly or not and also used to tachometer drive. The sensor monitors the voltage difference between a resistance which is on the battery circuit for ignition coil. When the ignition coil works properly, the electric current through the resistance is detected as voltage drop. This is confirmed for every ignition event with the crankshaft sensor and the camshaft sensor. If ECM detects a malfunction, no ignition is possible, so the engine would not start. If there is no ignition signal for a predetermined cycle for one or two ignition coils, an ignition coil circuit failure exists.

Battery drain in 3.3L motor

It would appear that steps need to be taken to determine the current draw . it can not unless there is a circuit for it to do so . Disconnect the earth strap from the battery and insert an amp meter in the circuit . IF there is a circuit for the current you will read that current and that will point to what unit is capable of using that current with out serious effect. Low current (up to 3amps ) indicates lights so check boot light still on-glove box light on- interior light on-head light module faulty etc.; Higher draw then look for ECM working when it should be off--sensors operating from shorts __HO2s sensor ABS unit operating. Starter motors I would discount because if the solenoid was operating the starter would be spinning the motor. Check that the audio systems are not operational with out making noise .Units I would be checking would be automatic units that draw through a relay and a check for this would be to watch the amp meter for a change as each power wire to the relay/s was removed and re installed . IF you find a relay that causes a variance I would replace that module and recheck the current draw.

I have prob.with battery going dead. while

It could be quite a few things, but if you could get a hold of a hall sensor attached to a digital multimeter, you might be able to find where the draw is coming from.

The hall sensor can detect current in a wire, so basically with everything on the truck off, you start at the battery and try to find current draw. There should be some current in your large + battery wire, just follow that out and test each wire where it splits off and it should tell you more information.

Some local parts stores have alternator testers where they put a clamp probe over the alternater wire... this is a hall sensor. Some local parts stores might be nice enough to let you borrow it out in the parking lot to try to trace the problem.

Not a specific answer, but hope it helps get you somewhere to start.

There is a wire is the starter that needs replace but cant get to needing to know what the name of the wire is called. Its a copper wire thats connected to the starter

if it's a big wire about 1/2' thick, it is the battery cable from the battery positive post to the starter, it provides the heavy current to run the starter.
Another small wire is the 12 volts low current that activates the starter relay which in turn connects the battery cable to the starter motor.
what is starter doing or not doing?
Starter System The starting system cranks the engine at a speed fast enough to permit the engine to start.
  • Heavy cables, connectors and switches are used in the starting system because of the large current required by the starter motor (11002) while it is cranking the engine.
  • The amount of resistance in the starting circuit must be kept to an absolute minimum to provide maximum current for starter motor operation.
  • A discharged or damaged battery (10653) , loose or corroded connections or partially broken cables will result in slower-than-normal cranking speeds. These concerns may even prevent the starter motor from cranking the engine.
  • In case of starting system difficulty, the operator may have discharged the battery before calling for assistance.
  • A road service procedure is described in this section to aid the service technician in such cases of a discharged battery .
The starting system includes the following:
  • the permanent magnet gear-reduction starter motor with a solenoid-actuated drive
  • the battery
  • a remote control starter switch (part of the ignition switch (11572) )
  • the transmission range (TR) sensor
  • the starter solenoid (11390)
  • heavy circuit wiring
Vehicles equipped with an automatic transmission have a transmission range (TR) sensor in the starter control circuit. This sensor prevents operation of the starter motor unless the transmission range selector lever is in the NEUTRAL or PARK position.
