The main problem is a bought a resistance of 150 K and the one that it needed it was of 100 oms. I trusted the person than sold me the parts to do his job. Since this is part of a hobby that I have, I didn't verify it. After going on circles about it, i ended up in the first place.
Thank you all for your help and patience. All the manuals were of many help. And specially to Ken Layton, you gave me the clue that I needed to finish it.
sarge, thank you for your help also, the jumper and the light bulb was a good trick.
Thank you all and i'll be writting soon with more challenges.
