WebApr 20, 2016 · If you put a resistor (say for an LED) on the positive cable then a short of the wire to the chassis will draw limited current. If you put the resistor on the return wire then a short to the chassis would blow a fuse or burn the wire up if it is not fused. A short on the return wire to the chassis will have almost no effect. Share Cite Follow WebJan 6, 2016 · If the resistor breaks or has any issues it may cause the fans to only function on certain settings. The cooling fan resistor is meant to send power to the fans in steps, so that the fans may operate at different speeds. If any of the individual steps or switches fail, it will disable the cooling fans from operating on that speed setting. WebMar 12, 2014 · The last thing to note though, having the internal pull-ups on, when your ATMega is at 5v, and the i2c device is a 3.3v only device, can cause issues. Or if you have the internal pull-ups on, and external resistors connected to a 3.3v or other voltage, can also cause issues.
