How to measure Voltage in Transforme for Fitness Treadmill


Transformer Test Procedure:1). Make sure that transformer wire connections (CON1) to the drive board are secured. Turn unit on.2). Put multimeter to the AC voltage setting. Insert meter probes into the transformer primary (red)wires as shown. Normal reading: 110V. This shows that there is power to the transformer.3). Test transformer output by probing on secondary (output) wires: black and black, white and white,orange and orange, yellow and yellow

Transformer Test Results :1). If there is no voltage across the primary (red) wires, inspect F1 fuse on the drive board and power to the drive board. 2). If there is voltage across primary wires but none across secondary wires, the transformer is bad.Replace it.

Transformer Wire Colors Normal Voltage Value:
Red and Red 110 VAC.
Black and Black 11-13 VAC
White and White 11-13 VAC
Orange and Orange 27-29 VAC
Yellow and Yellow 10-12 VAC

So what's a flyback or convergence option ??. Heck, even a stick-figure Diagram might do the trick. It's nice 2 have folks like ya'll sittin' 'round helpin' each-other out


The flyback is the large transformer that has the thick red wire coming out of it. The solder has a tendency to crack slightly which causes the FL231 Fuse to blow ( just to the right of the flyback) When the FL231 fuse blows the convergence option will disappear from the setup menu and the set will appear 3d with an arced picture. I am attaching a pic that shows the Flyback with a white circle, The FL231 is the yellow circled item next to the flyback11_1_2012_11_47_00_pm.jpg

I have an intermatic C8865 timer. i want to wire it into an EFM model AF150-1 coal stoker furnace, because the fire goes down to far inbetween actual times heat is called for. also have main switch for...


Intermatic C8865 timer is a 5-hour cycle timer that repeats same cycle each 5 hour period.
This timer has 120Volt clock motor and is 120V timer.
Timer has NO and NC terminals.
NO terminal turns ON when timer turns ON
NC terminals is ON all the time, except when timer turns ON. At this point NC terminal turns OFF.

You have 3 things: 120V timer, 120V honeywell transformer, 120V stoker motor/fan
The transformer needs to be ON at all times.
The stoker motor is going to turn ON when the cycle timer turns ON.

You have 120V cable with black wire, white wire (and bare ground, which connects to green ground screw and to other bare grounds and won't be discussed further)

Black wire is hot
White wire is neutral

Black wire connects to 'Switch common terminal' on timer.
Same wire also connects to black wire on Honeywell transformer.

White wire connects to 'Clock terminal' on timer
Same wire connects to white wire on Honeywell transformer and to white wire on Stoker motor.
So all the white wires are connected together.

Last wire is black wire to stoker motor.
This wire connects to NO terminals on timer.

Here is drawing.

Need wiring diagram for a carrier 383kav11048075? im replacing the icm281 control module. gas furnace


There should be a wiring diagram on the panel of the furnace. In the box of the icm 281 is step by step instructions.

Maybe this will help

Take notes on your low voltage wires from the thermostat and condenser. W Y R C G. Write down what color wires go to above terminals.

On your high voltage wiring,
Take the black wire from the transformer and put it on PR-1.
Take the white wire from the transformer and put it on PR-2
Take the black power wire from the panel interlock switch and connect it to L1
Take the white neutral power wire and connect it to L2
Take the black fan motor wire and connect it to HI
Take the red fan motor wire and connect it to LO
Take the white fan motor wire and connect it to COM
Then reconnect your low voltage terminal wires to W Y R C G.

Thats it.

Locating the ''flyback transformer '' on a rca mod #R52WH74


It is usually large and black. Its the one with the rather thick red wire coming out of it. The other end of that wire either connects directly to the picture tube or into a distribution block which distributes the high voltage to the 3 picture tubes (guns) in projection TV's. Be aware that this transformer produces high voltage and can store voltage even when the set is unplugged. I hope this helps.

I am replacing the flyback transformer


You should post here pictures of old transformer and point out what wire you want to remove, then I can give you an idea what to do as flyback transformer is not in front of me.

Problem


There is no "Flyback transformer" in the LCD monitor "Benq 17" model No. Q7T3". Such a component, a "Flyback transformer" is found in televisions and in Picture Tube type monitors. The red wire of a "Flyback transformer" is where 27,000 VOLTS comes out of to connect to the picture and such a voltage IS DEADLY so never enter a TV or computer monitor unless you know exactly what you're doing. To bring your hand too close to the "Flyback transformer" is to GET ZAPPED, you don't even have to TOUCH that transformer or the Red Wire that comes out of it!!!!

As far as a fuse blowing, NEVER PUT IN A FUSE WITH A HIGHER AMPERAGE RATING: it's there to protect certain components from being permanently damaged. If the fuse is blowing you must find out "why". There's got to be a short circuit in one or more components. Transistors, Diodes and Capacitors are easy to check for shorts. Transistors, Diodes are usually what short out. There's not much more I can say here.

A schematic diagram that shows the voltage on the many components of a running LCD circuit is what you need to find out where volatges should be. If a voltage is missing you must find out where the problem stems from. There are other ways to test circuitry, with an oscillascope and a schematic diagram that shows test points and the wave pattern that's suppose to be present.
