3 pins on DC jack of Dell 9400? replacement advice please

DC jack on 9400 is bad.

I want to connect the power solder points to new wires that lead to an external jack made of anderson connectors.

if i just made the 3 connections anew, it would work straight up?

i have 2 really lame soldering iron, that resentfully solders anything, i am thinking of soldering it with a large red hot iron nail by the cooker.

else if i can chop open the exising DC jack and solder leads onto its copper connections, would i probably kill the mainboard with the force of trying to chop it open?

please recommendations if i am up the wrong path.

Thanks!

edit - for future reference, here is some info on the dell dc jack and it is a gay jack for jockstrap lovers.

OK i think i have a solution that will work as a guide for anyone that doesnt have a 300 dollar soldering station to unfasten all the pins and put in a new DC jack...

The DC jack is surrounded by metal that is connected to all the - plugs.

all the pins save the 3 near the chips are ground, it seems, the 2 middle ones register zero resistance to the ground also, and it is the live that is faulty and doesnt make a connectionto the MB, i took measurements from the disconnected wires of the input plug to all the pins.

Solution: instead of soldering the little 3rd pin at the back of the jack body, you can simply wrap very tightly a small wire around it, very securely so it mainains a good connection.

then you solder a + pin, which is 2 flat copper ribbons next to the little pin, and the - which is the sheilding or the pins underneath.

voila.

for the moment the only issue is the 115k resistance between the little pin and the ground, i figure it is because it goes through chips in the mainboard rather than being a fault of my dodgy jack, i will dremel the top of the little pin tomorrow to isolate it from the jack and i will be able to tell you.

drill a wire sized hole into the back of the underchassis next to the DC hole and pass the 3 new wires through and make a new external plug, use lots of pvc tape to fasten it.

hope that helps anyone in the same hassles.

hi

sorry that was a while ago, i dont think i had a camera there at the time and i was just to absorbed in the task to think of it. you have to be really careful to wrap the middle wire in pvc tape... i think i left it bare going 1 mm near the other wires and now i wonder if it may short one day but it has held up for 3 months now and the pc is good as new...

sorry i dont have a pic, just i think the description is pretty precise for the + - monitor pins on the dc jack, if you copy them exactly you should be ok.
