Power off within one second after wich on


Hi
Some short circuit in supply line output in the secondary winding of the switching transformer may be drawing to much current making the protection circuit shut it down.

How to identify the matching transformer terminal by means of terminal resistance? and which terminals is for input or output?


Doing a resistance test on a transformer will not give the information you require as you will read very little, if any resistance. What you need to do is an impedance check and that gets involved. If it is a normally wound transformer, not an auto transformer, you can isolate which is the primary and the secondary windings. Unless the transformer is a multi voltage input unit, the primary side will have continuity through only two terminals. The secondary could be more than two if it is a multi output voltage one. If the transformer is a step down, the primary windings will be the thinner wired windings and vice-versa. To actually test the transformer, get hold of a transformer with about a 20 vac output and try it across the two terminals you have identified as the primary windings, you should ge a proportional voltage of the actual output. eg. with 20 vac input and a 2 vac reading at the secondary, the actual output would be 11 vac if your mains voltage is 110 volts. Take care that you are using the transformer at the voltage it is designed for, otherwise it will overheat and burn out.

Radio works with the batteries but not the mains all terminals and connections are ok any ideas ?


Check glass fuse inside near transformer, if this is ok, there is a thermal one on the tranformer windings itsself where you need to cut the tape off the transformer windings doing with caution. Not to cut the transformers windings, once located desolder and replace the part from RS components or Maplins. I had the same problem as you, I bypassed this on the tranny and mine is fully working. This item is a safety feature for the transformer.

WAVE radio transformer bad ???


If you can check ohms,you can also read volts. Open the radio again and look for DC volts on the rectifiers capacitors.They look like :cans", normally the color is blue. Check for positive dc v. against chassis ground. If no + tension,your rectifier or your secondary are open.

Transformer secondary out ???


please my name is dele i have this BOSE radio/cd system model number is AWRC2G which transformer burnt out rightly, that the input is 240volts which output is the problem and in nigria. please i just want to know the output on each coloured wire of the secondary that has 8 wires output from the secondary (2 purple - brn = volt, 2 blue = volts, and 2 black - gray = volts. so that similar that i can use to work it.
thank you
