I called the guy and he said I can return it and get a replacement, but I don't want to go through the hassle. Anyway, I re-measured the resistor after Olin's doubt that I waited long enough after the board was powered off. This is what I found: The resistor *may* actually be a 100 ohm resistor but could have been defective out the manufacturing plant OR could be a cold solder joint for the following reasons: When I initially touched the ohm meter leads to all other 100 ohm resistors= , the reading was instantly 100 ohms regardless of how much pressure I put on the leads. When I touched it to R130, initial value was around 3k, but as I increased pressure on the solder joint (maybe from 0.1 to about 1 kg of "weight" from my arms), the resistance of R130 quickly dropped. If it's simply a matter of reheating the solder joint, I don't want to bother with the hassle of sending it back and getting a replacement. But is there a possibility that the resistor itself is defective? --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
