Question about Weller Wesd51 Digital Soldering Iron Station Kit

Open Question

The tip does not heat. The digital readout goes to 902 after 3 seconds. the tranceformer reads 27vac. Pin 2 to 6 read 5.8 vac. Iron Resistence Pin 2 to 6 is 10.5 homs. Sensor pin 3 to 4 is open. Is my heater/sensor the only problem?

SOURCE: I have a Weller 1002B soldering station. Haven't

Hi, I'm not sure the tip is defective. Check that the tip is screwed in tight. If it is not good and tight the tip will not get a good heat transfer from the solder wand. Hope this helps. If the wand will heat then the tip should.

SOURCE: iron will not heat---could it

If the iron is not getting hot at all then the tip is not the issue. I would goto a local hardware store like home depot or lowes and buy a replacement wall plug. You should first cut, strip back the wires and replace the plug as per its instructions. If the Iron still doesn't heat up after this you should unplug it and dissemble the body of it, you have to unscrew the 3 screws on the top and slide the body down. There will be wire nut connections for the electronics from the wall plug cable to the actual iron, check that they are connected properly. Often there is a break in the pinch point of the cable at the end of the irons body. For solving this I like to cut the wire below the pinch point, strip the wires back and redo fresh connections at the wire nuts. Good luck!

How test a thermistor


Hi jorge

Hi
To test your thermistor you will need:
Soldering iron
Multimeter or ohmmeter
Follow the directions below to test your thermistor
1...Set the multimeter to resistance mode lowest setting.
2...Hook up the terminals of the multimeter to leads on the thermistor.
It does not matter which lead goes to the terminals, polarity is not important in this test.
3...Heat the soldering iron then heat the thermistor by moving your heated soldering iron tip to it.
Note: Check the multimeter reading as you are applying this heat.
A properly functioning positive temperature coefficient thermistor will show a smooth and steady increase in the multimeter
resistance reading.
A properly functioning negative temperature coefficient thermistor will show a smooth and steady decrease in the multimeter
resistance reading.
4...Look for other signs that the thermistor is faulty.
A steady reading that does not change, a reading of zero or a reading of infinity are all indications that the thermistor needs to
be replaced.
If the change in the readings is not smooth or if there is not any change, then this could also indicate a faulty thermistor.
Please take time to rate me.

I have a charging problem on a 06 mod harley davidson street bob.how do i test the alternator?


AHHHH the old charging system problems, lol.

Your stator is located on the left side of the engine (as your sitting on it), behind your primary(behind your compensating sprocket, and rotor). Yes, this is a little complicated to diagnose but I will try my best to help you out.

1. Start your bike, and put your multimeter on your battery(black to neg. and red to pos.).
2. at idle you may read 11.5-13.5 Volts, this is normal. now when you rev the engine to 3000 RPM your Voltage should jump to no more than 14.7 or very close to it. If it stays low It could be either your stator or regulator. If its way higher, you need a new regulator. But first, lets test the stator. Turn the engine off.

Locate the stator wires directly in front of your oil filter, see it going into the inner primary?? Ok follow those wires to the regulator, in fron of the frame kind of by the oil filter and front motor mount, but connected to the frame. OK, go it?? Unplug the stator from the regulator. Now your gonna be testing the stator so dont even worry about the regulator. Now that you have the wires from the staor in your hands ( your hands should be filthy by now, lol)

1. Set your multimeter to Volts AC. Youll be going to about less than 100 VAC so set it max off 100 or 200.
2. Remember that this is a 3 phase system so you should 3 pins, so youll have 3 readings, Pin 1-2, pin 1-3, and pin 2-3.

3. Touch your mutlimeter probes to pins 1 and to pin 2, with the engine on and at idle, you should be about 20-30 VAC around there.
4. As you rev the engine, you should jump about 20 VAC per 1000 RPM. This means that at 3000 RPM you should be reading about 60-70 VAC. Do this test with the other pins. Pin 1-2, pins 1-3, pins 2-3. You should have about the same readings on all of them, and, your readings should be steady, and not drop off or gain alot.
5. Remember about 20 VAC per 1000 RPM. But, dont go over 3000 Rpm.

Results:
1. If the AC voltage at the stator is steady at 3000 RPM at about 60 VAC., but, battery voltage stays at 13V at 3000 RPM with stator and regulator hooked up, You got a bad regulator.
2. If your not getting a good AC voltage from the stator, your stator is bad.
3. If the AC voltage from your stator changes drastically as you go up in RPM (meaning as you slowly go up in RPM the AC Voltage goes from 10 Volts to 60 Volts back down to 20 volts.) You have a bad rotor.

Thats pretty much the basics, lol. Also open your clutch cover and smell your primary, if its an overwhelming disgusting burnt smell, and your clutch is working. 99.9% you have a burned stator and needs replaced.

When i plug it in it goes to 902 degress but does not get hot and when i turn the heat down it goes up to 902


I had the same problem with mine. Try pushing or twisting the cord entering the soldering iron pencil. The temperature sensor can become disconnected if the cord gets twisted.

Rowenta Iron problems


inside the iron is a thermal switch that has failed to make contact. Dissassemble the iron and you will see a small white ceramic pin sticking up out of the heating chamber and on tip there is a small contact. Above it is another contact that makes the heating element work. Easiest way to fix is to put a small bead of glue on the housing to force the contacts together.
