Can't get power to foglights on my 2003 Explorer


Power is applied to the fog lamp switch which is a separately controlled part of the main light switch. When the fog lamp switch is turned on, power is applied to the fog lamp relay in the battery junction box which closes to turn on the fog lamps IF 20A FUSE 19 and 15A FUSE 44 in the BJB are OK. Setting the multifunction switch to HI closes the high beam relay in the BJB, removing power from the fog lamps and directing it through 20A FUSE 46 in the BJB to the high beam lamps. In other words, you can have fog lamps or high beam lamps but not both at the same time

the multifunction switch is set to HI, the high beam relay in the battery junction box closes

POWER SLIDING DOORS WILL NOT RESET OR LATCH


I don't think this is a power problem at all on this. I think you have a control board that has gone bad. The board is usually part of the switch on the door. I assume these are both controlled on the drivers side door armrest. Sometimes cleaning and reconnecting is enough but replacement is the best option.

Dishwasher code F4E1


The F4E1 is a code that signifies a WASH MOTOR issue. Specifically, no Communication. This is usually caused by:
A loose connection in Wash Motor Circuit, Motor Communication Circuit and/or an open wash motor.
1. Unplug dishwasher or disconnect power.
2. Check all connections in Wash/Rinse Circuit and Motor Communications Circuit. Fix/replace an open connection/part. Motor fuse on control open.

Using keypad press "Heated Dry", "Normal Wash", Heated Dry", Normal Wash, and the "cancel button" to reset.
Start a cycle and listen for 2 relay contact clicks at the start of interval to confirm both the pilot and motor relays are turning on.
These relays provide power to the motor, but the motor does not start until it receives a start command later in the cycle). If hear only 1 or zero clicks and wash motor does not come on later in service cycle, and there were no loose wire communication wire connection when checked above, then unplug dishwasher or disconnect power and replace control.

Motor wont start


Assuming the motor shaft is not frozen and the rotor turns freely by hand
All single phase induction (No brushes) motors require energizing a "starting" winding for a second or so to get the thing turning.
Once the armature in turning the "run" windings take over and the start winding is turned off. If power is left on more than a few seconds without the motor starting, the starting winding will be permanently damaged. It can tolerate power for only a few seconds.
The momentary connection to the start circuit is controlled by any of several different methods. The most common system is a switch located at the opposite end of the motor from the output shaft. The switch is in the end cap and there is a flyweight on the armature that opens the switch when the motor gets up to speed. If the switch fails to make contact when stopped the motor won't turn. The contacts can be worn to the point of not contacting or it may have sawdust or other matter between the contacts. Whatever the reason the contact is not making connection to the start winding.
Another method use is an "Inrush" relay. This may be located in the motor or anywhere else like the manual switch box or another box exclusively for the relay. Radial are saws frequently use this system. When the motor is powered up the current is several times the current that it takes to keep it running. This high current (inrush) is detected by the relay and snaps closed until the current falls to the lower running condition. In this design the relay is open at rest and closes for a small amount of time at power up.. In the first design the contact is closed anytime the motor is at rest and opens when up to speed.
Look for a fault in these areas.
There are many other ways to start single phase induction motors, but these are by far the most common.

Thermo fan will not work on 1996 klx 650, when engine is running or hot, there is a wire to the sensor and another which is broken, beside it. Should the broken wire be connected to something? If so, what?...


Hello;
Let's figure this out. Broken or otherwise disconnected wires usually cause an open circuit preventing adequate current to a componant. Two wire switches act as light switches do. they either close or open a circuit.In this case, the warning lamp or fan relay is ativated when the temp rises. Cold, the circuit is open/ broken preventing any controlled componant from activating.
First check for any power/voltageat the disconnected wire and the connected wire. Which ever wire that is powered is the supply wire. The one without is your controlled componant wire. Touch the two wires together, bypassing the switch. The fan should come on and turn off when disconnected again. Ignition switch needs to be on.Because of the load the fan pulls, a relay is between the fan and switch.
The switch closes powering the relay, then relay close contacts closing a secondary circuit which in turn permits power to the fan. The fan circuit is powered by the battery and controlled only by the relay.
Yuup, two circuits. Switching and fan drive circuits. Yes, Hook the wire back onto the switch after testing as outlined here. Good Luck and remember to always verify power (fusec ondition). _Ned_

My WHARFEDALE DIAMOND SW150 SUBWOOFER does not work. the light (red) comes on when connected. but no sound. I've tried direct from speaker and from receiver connection. doesn't work. Any advice


After finally finding the circuit diagram for the Wharfedale SW-150 sub woofer, I've managed to identify and fix a fault which has the same symptoms as yours.

The problem was with the largest of the two relays (Relay 1 in the attached photo).

wharfedale-diamond-sw150-subwoofer-p251q2jbxgw5dhyonjje5nyi-1-0.png

The circuit has two power rectifiers, the first rectifier provides the small current for the system to operate in standby. Relay 1 is normally closed and this turns on the secondary power rectifier that powers the amplification circuit.
Relay 2 (smaller and black) is used to prevent the speaker from popping every time the auto-power switches on/off, it uses a delay to allow the amplifier to stabilize before activating the relay which connects the amplifier to the speaker.

On my system the power LED was lit, but the little click that happened about 2 seconds after power-on, was no longer heard. The little click that was missing is the sound of the smaller relay connecting the speaker. This relay was not activating because the amplification circuit had not been powered.

The larger relay does not need to activate to turn on the amplifier, as it is normally closed, meaning the the default connection state is to provide power to the amplifier. The relay is only used to disconnect the amplifier when the auto-off feature kicks in (or the system over heats). I could test this relay was clicking by connecting pins 1 and 3 on the temperature switch connector.

So the relay was not connecting properly in the closed state. This is what the relay looked like on the inside.

Heat will not turn off.Removed thermostat wile


Hello
Could be a stuck control relay,Tsat completes a circut for this relay to engage,once relay contacts are closed heater will start.and stay on until you reach temp.

once temp is reached relay will open and heat will shut down.

By disconnecting all power to heater your forceing relay to open.or simulating a satisfied temp.

I would have a service tech look at your control relay and t stat.

Before you begin to diagnose and test the stop light system (that's what's it's called in the service manual), you should look at the following
wiring diagram to try and understand how the system work. This will help you to logically walk through the diagnosis process.

TESTING FOR “OPENS” IN THE CIRCUIT

7c178f9.jpg

Continuity Check Method
The continuity check is used to find an open in the circuit. The
Digital Multimeter (DMM) set on the resistance function will indicate
an open circuit as over limit (no beep tone or no ohms symbol).
Make sure to always start with the DMM at the highest resistance
level.
To help in understanding the diagnosis of open circuits please refer
to the schematic above.
1) Disconnect the battery negative cable.
2) Start at one end of the circuit and work your way to the other
end. (At the fuse block in this example)
3) Connect one probe of the DMM to the fuse block terminal on
the load side.
4) Connect the other probe to the fuse block (power) side of SW1.
Little or no resistance will indicate that portion of the circuit has
good continuity. If there were an open in the circuit, the DMM
would indicate an over limit or infinite resistance condition.
(point A)
5) Connect the probes between SW1 and the relay. Little or no
resistance will indicate that portion of the circuit has good continuity.
If there were an open in the circuit, the DMM would
indicate an over limit or infinite resistance condition. (point B)
6) Connect the probes between the relay and the solenoid. Little
or no resistance will indicate that portion of the circuit has good
continuity. If there were an open in the circuit, the DMM would
indicate an over limit or infinite resistance condition. (point C)
Any circuit can be diagnosed using the approach in the above
example.

Voltage Check Method
To help in understanding the diagnosis of open circuits please refer
to the previous schematic.
In any powered circuit, an open can be found by methodically
checking the system for the presence of voltage. This is done by
switching the DMM to the voltage function.
1) Connect one probe of the DMM to a known good ground.
2) Begin probing at one end of the circuit and work your way to
the other end.
3) With SW1 open, probe at SW1 to check for voltage.
voltage; open is further down the circuit than SW1.
no voltage; open is between fuse block and SW1 (point A).
4) Close SW1 and probe at relay.
voltage; open is further down the circuit than the relay.
no voltage; open is between SW1 and relay (point B).
5) Close the relay and probe at the solenoid.
voltage; open is further down the circuit than the solenoid.
no voltage; open is between relay and solenoid (point C).
Any powered circuit can be diagnosed using the approach in the
above example.

TESTING FOR “SHORTS” IN THE CIRCUIT

To simplify the discussion of shorts in the system please refer to
the schematic below.
c2ba473.jpg

Resistance Check Method
1) Disconnect the battery negative cable and remove the blown
fuse.
2) Disconnect all loads (SW1 open, relay disconnected and solenoid
disconnected) powered through the fuse.
3) Connect one probe of the ohmmeter to the load side of the fuse
terminal. Connect the other probe to a known good ground.
4) With SW1 open, check for continuity.
continuity; short is between fuse terminal and SW1 (point A).
no continuity; short is further down the circuit than SW1.
5) Close SW1 and disconnect the relay. Put probes at the load
side of fuse terminal and a known good ground. Then, check
for continuity.
continuity; short is between SW1 and the relay (point B).
no continuity; short is further down the circuit than the relay.
6) Close SW1 and jump the relay contacts with jumper wire. Put
probes at the load side of fuse terminal and a known good
ground. Then, check for continuity.
continuity; short is between relay and solenoid (point C).
no continuity; check solenoid, retrace steps.

Voltage Check Method
1) Remove the blown fuse and disconnect all loads (i.e. SW1
open, relay disconnected and solenoid disconnected) powered
through the fuse.
2) Turn the ignition key to the ON or START position. Verify battery
voltage at the battery + side of the fuse terminal (one lead
on the battery + terminal side of the fuse block and one lead
on a known good ground).
3) With SW1 open and the DMM leads across both fuse
terminals, check for voltage.
voltage; short is between fuse block and SW1 (point A).
no voltage; short is further down the circuit than SW1.
4) With SW1 closed, relay and solenoid disconnected and the
DMM leads across both fuse terminals, check for voltage.
voltage; short is between SW1 and the relay (point B).

GROUND INSPECTION

Ground connections are very important to the proper operation of
electrical and electronic circuits. Ground connections are often
exposed to moisture, dirt and other corrosive elements. The corrosion
(rust) can become an unwanted resistance. This unwanted
resistance can change the way a circuit works.
Electronically controlled circuits are very sensitive to proper
grounding. A loose or corroded ground can drastically affect an
electronically controlled circuit. A poor or corroded ground can easily
affect the circuit. Even when the ground connection looks clean,
there can be a thin film of rust on the surface.
When inspecting a ground connection follow these rules:
1) Remove the ground bolt or screw.
2) Inspect all mating surfaces for tarnish, dirt, rust, etc.
3) Clean as required to assure good contact.
4) Reinstall bolt or screw securely.
5) Inspect for “add-on” accessories which may be interfering with
the ground circuit.
6) If several wires are crimped into one ground eyelet terminal,
check for proper crimps. Make sure all of the wires are clean,
securely fastened and providing a good ground path. If multiple
wires are cased in one eyelet make sure no ground wires have
excess wire insulation.

Dryer problem


with power disconnected
follow the wires from the start button, to a relay,
check the wires (both ends) of all leads to the relay and reconnect any that have fallen off. (crimp tighter if they have fallen)
Check door switch function and connection.
check timer connections
the relay start-button timer and door switch comprise a latching circuit, when the start button is pressed the relay is supposed to latch closed and supply current to heater and motor. if the latching circuit disconnects the relay does not latch closed, and only runs as long as the start button is pressed.
if nothing has disconnected one side of the relay has usually failed, and the connection is not being made to latch the circuit
replace relay

Dryer won't run unless we hold the button


The start button starts the motor heater and energizes a relay that latches closed to keep the motor and heater running untill the timer switch or door switch cut the power to the relay and the relay opens.
The latching relay has failed or disconnected
if all the cables are attached to the relay
replace relay
not an expensive item, good for another 10years
