	I was working with gas plasma generator . It had the option for external outputs and while checking the voltage at external 15pin connector i shorted 2 pins together after that it gave some burnig smell and unit got powered off automatically and i disconnected the ac power. while trouble shooting inside the controller it had powersupply board that was giving short at output (between positive and ground of 5v) it also delivers 12 v that looks fine. I need some expert advice on identifying the shoring component at the output side of the powerboard. It has many components like capacitor, resistor , inductor connected between positive and negative terminal. Visually everything looks ok. Please give some suggestions on this . Thanks i am waiting for your reply ...

	I'd still have rung the manufacturer first, however many times you ask the question. __________________ Good moaning!

	No this equipment is quite old and being used in R&D facility and the equipment manufacturer has stop manufacturing these controller as these models are obsolete right now. Thats why i am doing it by myself.

	Start by obtaining a circuit diagram. If the individual components have lost their identification, which sometimes happens when an electronic component is pushed beyond its design limit, the diagram will enable substitutes to be made in an attempt to get the equipment going again. Another option would be renewal of the equipment with a more modern replacement. Why are there two threads running on this topic when the CR4 Rules permit only one, please? __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856
