That's a great find, but given your experience with the circuit, and the different diagnosis, how does that change the likely cause of the problem? Why did the sense resistor get toasty?
- megous 8y agoYou don't need all that much power to toast such a small resistor. Looks like 0805 package, which would be rated for 0.125W max. Easy to burn. It probably burned because of something causing higher current draw than expected by designers. Short or whatvever. If it failed open, which would be expected, it might have acted as a fuse.
