Not sure where to go with this. Don't see this one much. I have 11.5V on F7040 with known-good battery plugged in. Sense resistor circuit near ISL is normal. Diode measurements are fine with pullup resistors. Both resistors are measuring 2kΩ (although they both were at 1kΩ before I changed them. No idea why.) I'm stuck now with No Battery Available message. Any ideas where to look next?

R5280 and r5281 should be 2kohms, R7051 should be 2.2kohms and r7052 should be 0kohms and r7050 should be .005ohms. i would check the resistance of the circuit at pin 17-18 of u7000 first.
