2003 Ford ka what colour is the wire for the alternator warning light on dash cluster


There isn't one ! This vehicle relies on serial data communication . The PCM sends an message on the data bus to the microprocessor inside the instrument cluster . The PCM controls the operation of the charging system warning indicator in the instrument cluster. The PCM is therefore responsible for turning the warning indicator off after the engine is started and illuminating it under fault conditions (when the generator is not generating the correct amount of current with the engine running). The warning indicator will also be illuminated by the PCM at key ON engine OFF, and stall conditions.
Charging System Warning Indicator
The instrument cluster receives the charging system status from the PCM over the SCP or CAN communication network. The PCM controls the charging system and the charging system warning indicator. The PCM is therefore responsible for turning the lamp off once the system is running and illuminating it under fault conditions (including stall conditions).
How to Diagnose Controller Area Network CAN Your best bet would be to take your vehicle to a qualified repair shop .

Dashboard and break lights won't turn on


don't break the brakes.
Test 1, do the head lights work, and not dim>?
if no, then fix that first. HL are super easy and work at all times
even keys i pocket they work,(safety)


the dashboard what? be more specific.?
on all cars , you year not stated. the dash lamps all come on key on
this the warning lamps self test.
the 2 critical ones are not the brake.
they are CEL and OIL pressure.
The CEL comes on to tell you the EFI is alive.
if the CEL does not come on, the lamp is burned out. or the EFI is dead.
If there is no EFI there will never be RUN.
the brake lamps comes on to tell you the hand brake is on.
and 2 more other reasons. low brake fluid, or bad brakes.
depends on year, not stated..

The electric power comes from the battery , clean the terminals first.
then to the main fuse box.
The main box feeds the dash box. and HL fuse
the EFI fuse are there and will have 12vdc on both sizes,
if not fix that next
there are be 3 fuse for EFI. (power, spark and memory)
if power or spark is 0volts , there will be no running.)

what year car, and what engine option.
size..

1994 legend speedometer works once in a while


92 or 94?
is fuse 22 loose?
did the CEL lamp in dash glow at this FAILURE event
or S, D or D4 auto tranny lamps flash? BINGO,

did you look for ECU/PCM errors first.? that be first .
is the odometer dead? too, at same time?
on this car the VSS module (veh.speed sensor)
sends the speed data to 6 other modules. the speedometer is 1.
so of the other 5 are dead, its the VSS dead, if not its a bad speedometer.
on of those modules is the PCM, that runs the EFI engine.
so scan it, on this old car, you insert the diagnostic jumper
(service check conn.)
and read the flash codes from the CEL lamp in the dash.
this will show 17 error, VSS bad. if bad (its bad or bad conn)
easy huh?

log in to alldata.com and read the how to read OBD1 codes
it will be something like this. (photos missing)
When a fault is noted, the ECU (otherwise known as the ECM) stores an identifying code and illuminates the CHECK ENGINE light. The code will remain in memory until cleared; the dashboard warning lamp may not illuminate during the next ignition cycle if the fault is no longer present. Not all faults noted by the ECU will trigger the dashboard warning lamp although the fault code will be set in memory. For this reason, troubleshooting should be based on the presence of stored codes, not the illumination of the warning lamp while the car is operating.
All models are equipped with a service connector in side the cabin of the vehicle. If the service connector is jumped, the CHECK ENGINE lamp will display the stored codes in the same fashion.
The 2-pin service connector is located under the extreme right dashboard on Integra, Legend & 2.5TL; on Vigor models, it is found behind the right side of the center console well under the dashboard.
Codes 1-9 are indicated by a series of short flashes; two-digit codes use a number of long flashes for the first digit followed by the appropriate number of short flashes. For example, Code 43 would be indicated by 4 long flashes followed by 3 short flashes. Codes are separated by a longer pause between transaxles. The position of the codes during output can be helpful in diagnostic work. Multiple codes transmitted in isolated order indicate unique occurrences; a display of showing 1-1-1-pause-9-9-9 indicates two problems or problems occurring at different times. An alternating display, such as 1-9-1-9-1, indicates simultaneous occurrences of the faults.
When counting flashes to determine codes, a code not valid for the vehicle may be found. In this case, first recount the flashes to confirm an accurate count. If necessary, turn the ignition switch OFF, then recycle the system and begin the count again. If the Code is not valid for the vehicle, the ECU must be replaced.
and this warning
On vehicles with automatic transaxles, the S, D or D4 lamp may flash with the CHECK ENGINE lamp if certain codes are stored. For Legend this may occur with Codes 6, 7 or 17. On Vigor and Integra it may occur with codes 6, 7 or 13. In addition, the TCS lamp on NSX may flash with codes 3, 5, 6,13,15,16,17, 35 or 36. In all cases, proceed with the diagnosis based on the engine code shown. After repairs, recheck the lamp. If the additional warning lamp is still lit, proceed with diagnosis for that system.

What kind of warning lamps are on? Is the Check Engine light on? Is the ABS warning lamp on? Is the OD light flashing? If you want your daughter to be safe while driving, ALL warning lamps should be dealt with and properly repaired. I see cars all the time where the children are driving mom and dad's old car with warning lamps all over the place. Then the parents freak out when the son or daughter gets thrown through the windshield during an accident because the car has been operated for several years with the Airbag warning lamp on continuously. I'm not saying that this is YOUR case, but I can imagine that if the vehicle is running as bad as you say it is, there has GOT to be warning lamps lighting up all over your dash. Don't let anyone tell you that the vehicle is OK to drive with ANY warning lamp on. Even if it is not doing any immediate damage to the vehicle, the problem is that your daughter is being trained to ignore warnings and when there IS a problem that can be dammaging to the vehicle or dangerous to your daughter, she won't know the difference! Again, I am not saying that this is how it is with you and your family, but I do see an aweful lot of this scenario where I work.

Without checking the car out myself and scanning your computer systems, this is the best advise I can give you.

I have a 2005 kia sorento and a light came on today next to the fuel it is yellow im not sure what the light means


There are many yellow lights on vehicles. They can be different on the same make and model of any particular vehicle depending on what option packages your vehicle is equipped with. Your best bet is to look it up in your owners manual. If you do not have an owners manual, I offer this advise: On all vehicles with the warning lamps in the instrument cluster, the yellow lamp are advisory lamps. ie. telling you that there is a malfunction with a system or letting you know that certain systems have been disabled. It is usually safe to operate the vehicle with the yellow warning lamps illuminated long enough to get the vehicle to a repair facility. (Check Engine Lights, Airbag Lights, Low washer Fluid Lights, etc.)The red lamps on the other hand, mean that the vehicle is not safe to drive before the cause of the lamp coming on has been resolved. (examples are the red Brake Warning Lamp, The Engine Teperature Warning Lamp, The Oil Pressure Warning Lamp.)
Since you stated the the lamp is yellow, I would say that it would be safe to drive the car to your local repair facility and ask them about it and get a professional opinion of what to do about it.

Key on engine running trouble code 55


Warning Chime Systems The generic electronic module (GEM) will sound the following warnings:
  • key-in-ignition warning
  • safety belt warning
  • headlamp switch ON warning
  • door ajar warning
------------------------------------------------------------------------------------------------
Headlamp Switch On Warning The generic electronic module (GEM) sounds when the driver door is opened while the headlamp switch (11654) is in the PARK or HEAD position, and continues to sound at a rate of 4 chimes per second until the headlamp switch is turned off or the driver door is closed.
  • When the headlamp switch is in the PARK or HEAD position, power is supplied through Circuit 293 (O/R) to the GEM.
  • When the driver door is open, the driver door open warning lamp switch (10B997)is closed and ground is supplied to the generic electronic module (GEM).
A delayed headlamps on repetitive chime will sound for a period of three seconds beginning twenty seconds after the key is turned to OFF, LOCK or ACC, the headlamp switch is in the PARK or HEAD position, and the driver door is closed. Delayed headlamps on is terminated by opening and closing the driver door again.
---------------------------------------------------------------------------------------
Door/Liftgate Ajar Warning The door/liftgate ajar warning functions as follows:
  • The generic electronic module (GEM) sounds a warning tone for one second when any vehicle door, liftgate window or the liftgate is ajar without any other door already open and the ignition switch is in the RUN position.
  • Power is then supplied through Circuit 627 (BK/O) to the door ajar warning indicator lamp which remains illuminated until all doors are closed or the ignition switch is no longer in the RUN position.
----------------------------------------------------------------------------------------------
Key-in-Ignition Warning The generic electronic module (GEM) sounds when the LH front door is opened with the key in the ignition switch and continues to sound until the key is removed or the door is closed.
  • When the key is in the ignition switch, the ignition key warning switch terminal and wire (11A128) is closed and ground is supplied through Circuit 158 (BK/PK) to the generic electronic module (GEM).
  • When the LH front door is open, the LH front door open warning lamp switch (10B997) closes and ground is supplied through Circuit 57 (BK) to the generic electronic module (GEM).
-------------------------------------------------------------------------------------
Safety Belt Warning When the ignition switch is turned to RUN or START from the OFF or ACC position and remains in RUN or START, the chime will sound for six seconds or until the safety belt is buckled. The safety belt warning indicator lamp (10C859) will turn on for 60 seconds, or until the LH front safety belt is fastened. Both the chime and lamp activate at the same time. If the safety belt is buckled when the ignition key is turned to RUN or START from OFF or ACC, the lamp will prove out for two seconds, but chime will not be activated. Any time the key is changed to RUN from START while the safety belt warning indicator is activated, the safety belt warning indicator will remain activated until either the timing sequence has been executed, or the safety belt is buckled.
