Follow the large alternator cable from the alternator to the isolator,this is where the voltage is directed,and it is most likely the problem,it allows the battery to be charged,but not used by the engine ,and vehicle accessories,and allows the vehicle battery to be charged and used by the vehicle.

    Follow the positive cable from the battery for the vehicle,it most of the time near the battery.But the battery cable will take you right to it,get ready to buy another one,cause it is most likely not working.NAPA auto parts usually has one in stock,don`t worry,the instructions come with it,I hope this is what you need to know,let me know,and please rate thank you.

I bought a new alternater and battery the alternater isnt charging the battery what else could be wrong


You have to check for B+ voltage at the heavier gage wire on the back of the alternator , could have a blown fusible link , plus the smaller gage wires at the connector that plug into the alternator mite have B+ voltage as well . You could look at a wiring diagram , that would show you . http://www.bbbind.com/free_tsb.html .Plus watch Test and troubleshoot your charging system Battery alternator testing

Alternator wont charge batteries


I can't give you more than generalities without knowing your vehicle model.
The alternator has several connections: Battery charge, Battery sense, and Field. The charge wire carries charging current to the battery. Since there is a voltage drop across this wire, a separate sense wire feeds the actual battery voltage back to the regulator module inside the alternator. The regulator then controls the current going to the Field terminal (a winding inside the alternator), which in turn controls the charging current. There may also be a separate Ground wire, but usually the alternator frame is supposed to be grounded through its mounting bracket.
The first thing to do is check each of the terminals for corrosion or loose connections. In particular, if the alternator has recently been serviced, or if somebody was working near it, check ring terminals on threaded studs to see if they have been left loose. Make sure the connections are clean and free of corrosion or arc burn oxidation, especially at the battery. Make sure screw connections are snug, but do not over-tighten - you don't want to break the connector stud.
If the connections and wiring look good at both ends, check the voltages on the terminals. The charge terminal voltage will be slightly higher than the sense voltage. The difference will be proportional to the electrical demand on the system. The field voltage will show a larger change with load (e. g., it should increase significantly if you turn on the headlights). Voltages must be measured with the engine running, so be very careful not to get the test leads or yourself caught in the alternator belt.

New battery , wires and plugs and still have trouble starting in the mornings, get a jump and starts. After running vehicle for awhile I turn it off and try starting it it will start.


check alternator output with engine running.you should have 13.5 - 14.5 volts if not alternator not charging.check alternator wiring to battery feed to alternator.check alternator voltage regulator wiring check alternator fuse make drive belt not slipping.and you have the correct cold cranking amp battery.bad old worn out battery cables will cause charging problems.because old battery cables put high resistance on the charging circuit.if battery cables old as vechicle replace them.

2003 FORD E150 NEW ALT AND NEW BATTERY STILL NOT CHARGING


Your wiring diagram shows a fusible link between the battery and alternator. Also shows an optional voltage regulator. Trace the wire from the alternator back to the battery. Look for that fuse and regulator. I will paste the diagram below.

Brand new battery,drove car about two days and the lights got very dim,stereo turned off,no accellaration,and now dead.(1994 mitsubishi mirage 1.8 liter)


It sounds like the battery has gone dead and will need to be replaced due to a bad Alternator. Once you get the car started, check the voltage on the battery, there should be 13.5 to 14.5 Volts. A fully charges battery should have 12 volts with the engine not running and once the engine is running there should be 13.5 Volts with the head lights on and heater on too. If there is less then 12 volts reading on the battery with the engine running, then replace the Alternator. You can pick up a Alternator at Auto Zone and they can give you the step by step instructions to replacing it with common tools and they can also check the Alternator in your car to before you buy the new one. Good luck and hope this helps and insect the wire harness from the battery to the Alternator, look for any sighs of damaged like corrosion and repair any damages to the wire harness.
