Hicham: did you check the GBT transistors or the diodes in the output section? I had that problem before and the transistors and diodes were shorted. do an ohm test between the red and black terminals on the outside of the machine? what reading are you getting there. you are still having a short in the machine.

Albert. they still do have relays that are see through but it is still the same process. even the contact are seen and they are black you can not open it and fix it. the easier way is to take it off board and use a dc supply and check it out. thanks for the nice comment.

If they only would be able to produce transparant relays it would make fault finding looking for burnt contacts a bit easier. But since they are mostly only housed in black plastics they probably are safer and easier to manufacture.

keep the good share.

i have 1 question? i am working on Cebora tig 180. with yellow led on, i found a faulty open resistor with 268OHMS reading instead (red violet black) so it should be 27ohms, when i replace it by new 27ohms 0.5w it get burned again; in the board there is no short; regulator voltage is ok, the ics are not hot. so please have you some suggestions how to attack the problem quickly? thanks in advance
