content: Hi. I am so new to all this sorry if I’m in the wrong place.Okay I bought this 898d+ soldering station from sears long ago I lost manual and I don’t know who it’s made by I looked at sears website and it says GHP.anywaysSo I dropped my station and to attempt to catch it b4 hitting the ground I grabbed it by the solder handler cord causing 2 wires to rip from the connector.As I went to repair it I accidentally disconnected the rest, so I totally ripped off the wires and don’t know what pins to solder them back to I’ve looked online everywhere for a wiring diagram and found nothing. The connector has numbers 1-5 but the wires are colored I opened it up on the board to see if thy have something to help guide me but no. The board says “ Youde898dv11”The solder iron”s board says “ youde935vb”I hope I make sense.. sigh yea I really don’t know why or how I do these things I usually can fix stuff by simply opening it and repairing lolThanks

content: I would suggest opening the unit to see where the pins in that socket are connected to. Or. open up the handpiece and see where the wires go.You'll have two wires for the heater element (AC voltage, most likely 24..28v or ~12v) , one wire is most likely earthing and one wire should be the temperature sensor.If you don't want to open up the unit, you could use a multimeter... place a lead on something you know it's ground (ex the negative of the fan inside the handpiece for hot air gun) and then use the other probe to measure the voltage on the pins ... if you measure some AC voltage you'll know that's your power. If you get continuity when checking for resistance, that's probably the earthing pin. The other one will probably be the temperature sensor.If you look inside, you'll see two wires coming from a triac or something that controls the AC voltage going to the heater element, so you'll know those two wires are power. You'll see the temperature sensor wire going somewhere else near some opamp or comparator chip, so you'll figure it out quickly, and the earthing pin should be screwed to the case right there by connector, or should be a green wire going to a screw that holds the circuit board screwed in the unit.Alternatively, you can figure out which wires are for the heater element by measuring the resistance across the wires ... most likely it's black and red for the heater element ... a 24v 50w-65w-ish heating element should have a resistance in the tens of ohms

content: Hey thanks for replying ..I did open it up to do just that and the wires didn’t have numbers and the wires changed to all white wiresThen I open the handle or solder iron itself thinking maybe the colored wires actually had numbers on it and they didn’t it’s a blank board :0

content: I have what appears to be the same model as you. However, when I checked the wires anti-clockwise from the indentation following the numbers on the connector are 1 red, 2 white, 3 black, 4 green and 5 blue. Obviously it's not quite the same as I have no yellow!I have worked out that the heating element is connected between 1 and 2 (about 3ohm), 3 is ground and thermistor is between 4 and 5 (about 48ohm cold and 120ohm hot). Once again yours might be different.

content: Your soldering station is quite common.They come in many brands ,Baku ,YiHua, ATTEN ,ect.The handle is the same for all of them. Look directly at the Iron plug and hold it so the notch is up. In a clock wise direction from the right side of the notch is pin 1 - 2 -3 -4 -5 The bottom centre is pin 3 Ground (Black ) On the right side is pin 1 and 2 Sensor wires.Pin 1 Red (pos) .Pin 2 White (Neg). On the right side is the heating element .Either direction is fine yellow and green.If your still unsure just buy a new handle.They're about 4 or 5 bucks . The 852D 936 937D 898D 937D use the same 5 pin handle.
