Re: Grey Jaguar No Power Out

Daniel,
The resistor is read the other way indicating it is a 470K (yellow, violet, yellow) while the gold band indicates 5%. In the schematic it is the bias resistor for the current sense amp, R43. This resistor centers the opamp operating voltage so that it varies around a quiescent 3.3v/2. When you try to use your Jag what is the color of the LED telling you?
