Question about 2003 Ford Escape

1 Answer

'03 Ford Escape 2WD 3.0-V6 -- alternator tests good out of vehicle, new battery. Not charging. -- When the ignition is on: the big wire that is screwed onto the alternator has power, one of the two small wires that clip onto the alternator has power and the other does not. 15A "ALT" fuse and 120A main in fuse box by battery both check good. Fuse box in passenger compartment has nothing listed for alternator and all fuses check good. Is there another fuse somewhere else or a fusable link?

So, dose it need a jump start every time? Have you tested your battery? Look, I'm suggestioning that your battery is messed up and your alternator is working now. Start your truck, and unhook the battery, if the engine keeps running, it's not your altenator or regulator. If it dies, then it's likely the regulator.

This feature is programmed into the smart junction box(interior fuse panel) If your vehicle was originally equipped with this feature then you may just need to have it reprogrammed or turned on by the dealer with their scan tool. If it was not originnaly egipped then the smart junction box would have to be replaced.

follow the wires from the alarm itself and trace it of that is not the problem then use a test light between the battery terminal by disconnecting the negative terminal and connecting a test light to the cable and the other end to the battery itself if its out no draw but if lit there's a draw pull fuses one by one with the door switch pressed in to nit get a false reading and when you find the test light goes out that's the problem use the chart guide to find out what # it is and that's yer problem solved

2006 ford escape xlt. New alternator.New batteryWon't stay started while blinkers,heat,air and radio are in use..lights inside bright...lights on dashbooard very dim.PLEASE HELP VERY LITTLE MONEY


Is the charge indicator lit , or battery symbol lit on the instrument cluster ? The charging system on your vehicle is computer controlled . Do you know how to do automotive electrical system testing ? Test for B+ voltage at the alternator connections . Heavy gage wire on the back of the alternator should have B+ voltage ,plus pin #3 at the connector should also have B+ voltage . Your best bet , take your vehicle to a qualified repair shop .

Already replaced new battery, new alternator, fuse, and pt connector - voltage sits at 12.9 running - system still not charging?


It isn't a good idea to disconnect the battery while it is running as the resulting voltage surge can damage electronics. Obviously if it isn't charging there won't be much of a surge...

Some alternators are mounted in rubber to cut noise and vibration. This type needs a ground wire which is sometimes forgotten during replacement and sometimes the ground wire just breaks.

A standard alternator only needs two or three wires and sometimes a ground wire. If the direct connection to the battery is good, the ignition light wire intact and working and if needed a battery sensing wire (though this wire isn't often needed in the last couple of decades) the alternator, if it is any good, will charge the battery at the regulated voltage of about 14.5.
If you are sure the alternator is a good one and it isn't charging the connecting wires must be at fault and need to be checked.

There is one other possibility and that applies only in the case of smart charging systems. If your car has a smart charging system the alternator will have several extra wires, usually plugged into the side of the machine.
The alternator works in a similar way to the standard unit except instruction from a separate control unit is capable of reducing or suspending charging. The smart charge black box talks with the engine management black box and charging is suspended during acceleration to cut fuel consumption or improve acceleration. A fault in the smart charge system can prevent the alternator charging.

Disconnecting the additional wiring will allow the alternator to perform its normal function without interruption. The ignition, charge or battery light is controlled by the black box and can do strange things that mean nothing when the smart charge is disconnected.

Alternator wiring harness


An alternator can run on two wires, the thick wire is the supply to charge the battery, direct to positive, via fuse box or starter supply. The thin wire possibly blue on Fords, is the energiser wire from the dash charge light, without this connected the alternator will not charge. If on the new pigtail two wires are thick (30amp) you can ignore one, some vehicles double up on the charge supply wire.

check your battery make sure it is able to take a charge. ,if the amps are good check your connection, from altenantor to battery. check voltage drops, battery drains. Your problem most likley seems to be
your battery. Your starter might also be draining your battery. You ll find the problem keep looking.

ok we have four connections at the alternator( black wire is ground) (white with blue positive direct from the battery)
and two wires connector in the regulator(yellow with black that goes to charge indicator the red light and goes to fuse 7 10a fuse block inside) the blue with yellow goes to fuse 65- 7.5a in the left fron engine comparment fuse box))#1 check for ground at the black wire= #2 check for positive at the white with blue wire (allwas with power) this wire is protected with 100a fuse is in the left front engine comparment fuse box,
remenber== check the 100a fuse
and the two fuses that protect the regulator.
when you turn the ignition switch to the on position power goes to the alternator by the yellow black wire and activate
the alternator to work.

Replacing alternator in 2004 escape


Have the whole battery/charging sytem tested. If it has an external voltage regulator or a bad battery, these things can kill a perfectly good alternator.
