Electric motors all typically work the same way. A current is run threw a loop in this case the copper coils in the center. This produces a magnetic field. The field magnets surrounding the copper cause the center + shaft to rotate one way. Now normally once the copper center rotated to a certain point it would reverse direction. To keep this from happening the copper that contacts where the current comes in is designed such that it reverses the flow so the center part keeps rotating the correct direction. This flip flop of current repeats and thus your motor keeps rotating in one direction.

I have a 2004 astro van and the transfer case control module is only passing the encoder motor 4.5 volts.


Was the transfer case control module check for DTC'S - diagnostic trouble codes ? Need professional or factory scanner to check these code's .
SERVICE AWD LIGHT ON , DTC'S are stored . Your best bet , take it to a qualified repair shop.
Do you know what DTC'S are ????? The AWD system can set a few of them .
DTC C0300
DTC C0305
DTC C0308
DTC C0309
DTC C0310
DTC C0315
DTC C0374
DTC C0376
DTC C0550
DTC C0611

Do you know what a pulse width modulated (PWM) circuit is ? You can't check power feed to the encoder motor with a volt meter , you will get a wrong reading . A lab scope is the best tool .

The encoder motor is controlled with a pulse width modulated (PWM) circuit provided by the transfer case shift control module. This circuit consists of a power supply relay, Motor Control A, and supplies voltage to the motor. The Motor Control B circuit is a PWM driver that varies the duty cycle to control the amount of current through the motor to ground. The transfer case encoder motor can be turned ON and OFF using a scan tool. You may also monitor Motor Control A and B circuits using a scan tool.

Digital input cable optical


The Alesis doesn't have an optical input.

It will only receive digital input in PCM, at the sample rates shown on the front panel - 44.1k to 96k

If you're trying to feed it an encoded Dolby Digital, or similar Home Theatre-type signal, it will not work, as these are not PCM-encoded signals.

Error code 5100


Error code 5100 indicates that Carriage Return (CR) error occurs. This error rise when carriage unit (the part that function as cartridge housing) does not move properly. Here are some possibilities of the problem:
  1. Carriage unit is faulty so that it cannot 'read' film timing **** strip (film encoder) properly
  2. Film encoder is dirty. Film encoder functions as a guide for carriage unit to move to the correct position it should be. Carriage unit 'read' the encoder by flashing a light from a LED. Dirty encoder sometimes make the light direction is deviated.
  3. Foreign material blocking carriage unit path. Please check inside the printer and remove it if any.

If carriage unit is faulty, you need bring the printer to the service center to get part replacement. For dirty film encoder,sometimes you can still clean it by using moistened cloth. I hope this will HELP you. Thanks.

Ecoquest Purifier was working when I went to work. When I returned, it was not running and would not start


Hi.

The RCI Cell must probably be replaced, this must be done about every three years. Ecoquest has no website or online support. You can get support calling the number listed on the manual below.

The part costs about $90, parts available here.

Replacement is explain at page 15 in manual available here.

There is also a debate on health concerns related to ionized air purifiers. Here Ecoquest answer, stating the product is safe.

On the other hand:

The Dangers of Ionic Air Purifiers

Ionic Air Cleaners

Please read also this article.

Before replacing any part I suggest to read the articles. Ozone related concerns have caused the recall of other similar devices.

Regards.

Ginko.

Canyon 4wheeldrive light turned on


Checking the 4X4 control module for DTC'S - diagnostic trouble codes is what you should done . Need a factory or professional type scan tool , no an OBD2 code reader . Looking at factory service repair info. description of how it works , an testing is how to diagnose . Not guessing an throwing parts at it .
DTC B2725
The accessory switch circuit consists of 4 modes. The transfer case shift control module supplies 5 volts to the switch through the switch signal circuit. The current travels through the resistor of the currently active mode. The current on the switch signal circuit is monitored by the transfer case shift control module. The voltage on the switch signal circuit will vary depending on which mode button is pressed by the driver.
The transfer case shift control module constantly monitors the switch signal circuit to determine the condition of the accessory switch circuit.
When each of the modes are selected they complete a circuit through their own specific resistor. The transfer case shift control module continuously monitors the switch signal circuit to determine whether the Neutral, 2HI, 4HI, or 4LO mode was selected by the driver.

DTC C0327 Encoder Circuit Malfunction
The transfer case shift control module has 4 encoder circuits, and each circuit is supplied 12 volts. These 4 circuits are A, B, C, and P, and each circuit runs to a switch located inside the encoder/motor assembly. When a particular encoder circuit is active, the switch is closed, and the 12 volts are grounded by the switch inside the encoder.
The transfer case shift control module supplies 12 volts on all the circuits. The module can interpret the location of the transfer case shift position when the circuits are grounded.
This DTC detects a fault when it compares the shift sequence/strategy to a chart located in read only memory (ROM), within the electronic control unit (ECU), within the transfer case shift control module. This is accomplished by the module reading the different combinations of encoder signals being grounded while others remain high depending on what mode or range the transfer case is in.

DTC C0550 ECU Malfunction
At each power-up, the transfer case shift control module runs a self-test on the following functions:
• EEPROM Checksum
• ROM Checksum
• RAM Checksum
• RAM Malfunction

I suggest your take your vehicle to a qualified repair shop .

Hp psc 2400 scanner motor stuck in repeating motion


Unfortunately, in this case HP's support site doesn't offer a lot of help. See here. or here.
This article will get you part way there if you decide to dig in and try to work on it yourself.
If you want to talk to the HP techs, see here.
If you're interested in reading a forum full of posts about the same issue, see here. and here. Read far enough and you'll see some solutions proposed, some of which may work in your situation.
Apparantly, if the scanner doesn't correctly read an encoder strip on the underside of the glass, which causes the motor to keep engaging even when the scanner bulb is fully retracted, and the belt starts slipping gears, causing the noise, etc.
And when the code isn't read, the alignment fails and the printer won't work. That's what I remember from the last time I looked into this, anyway.
Good luck with it...
If you don't feel comfortable yourself, perhaps some able and competent friend will be willing to have a look.
Otherwise, you'll have to get it serviced.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
If I've managed to answer your question or solve a problem, please take just a moment to rate this post....thanks!

Drivers window does not move and sometimes display reads drivers side front door ajar and i cant even open gas cap


So as not to be repetitive, for the failure of your power window or windows, review this handy diagnostic article, which identifies the possible causes, from a bad fuse, relay to window motor, etc.:
http://yourhandymanzone.com/Your_Handyman_Zone_How_To_Pages_Vehicle_Car_Zone_Cars_Trucks_Vans_Windshield_Windows_Window_Does_Not_Roll_Up_Down.htm

For power door lock failure, similarly, see this handy diagnostic article:

Chevrolet Suburban 4 Wheel Drive Indicator Lights


Just serviced my own 4x4 Suburban, by buying a 2nd hand encoder motor and replaced the old one, which was trashed by the winter salt. The device is prone to failure since it's made of alluminium and water has an easy time of entering the unit and trashing it.

CAUTION: Abbreviated gratuitous information of how an encoder motor was serviced. If unqualified to deal with repair, seek professional service.
CAUTION: Read at one's own risk.

To replace it, you need to crawl under the vehicle and remove the front drive shaft;

Disconnect the electric harness to the encoder motor, followed by unbolting it.

Take replacement encoder motor and install. There may be an issue with aligning the cogged cam of the transfer case to the encoder motor. If so, the vehicle's 4 wheels will need to be raised off the ground. The engine started, transmission in Park, and using a Vice-Grip® wrench gently rotate cam clockwise approximately 1/16 to 1/8 of an inch, then while set in this position, stop engine. Now attempt to align and attach the encoder motor.

After successfully attaching new encoder motor, attach its wiring loom.
Test vehicle.

Carrier jam


This strip is called the encoder strip. I found this fix online, which is very similar to the 5470.

http://www.fixyourownprinter.com/forums/printer/28494

The only difference you'll have is the encoder stip fits INSIDE the cartridge carrier. I'll attach a photo to show you where. Good luck!

I have a Roland Versacamm and as it's printing an image that is supposed to be a rectangle shape 40"x60"...as it prints out the image is not straight it actually looks wavey like a flag? The printer was OK...


this sounds like a scan motor error. clean encoding strip and test. If still wavy remove scan sensor the one that reads the encoder strip, clean with alcohol, replace and test. if still bad replace encoder strip and the eye that reads it.
