PPBUS is cycling from 9V to 12.3V Stuck at 5V. With Fuse connected one port amp draw is significantly higher than the other. Removed the FUSE. F5200 I get 12.3V stable at C5255. Client said it just stopped charging and eventually the battery drained.

PP3v3_g3h short to ground. Injecting voltage but nothing heats up. Drawing a good 2.5 Amps

Removed the Fuse. PPBUS is .120 and PPBVAT is .453. Is I shorted ? I injected voltage and not drawing any amps. (0.002) I removed RD590 and PPVIN_P3V8AON jumped from 0.120 to 0.450 which is the correct range as per openboarddata. Hence I feel there is a short. How to proceed ?
