was [rev B test log] now let's restore that test board

[rusefillc]

does not DFU as arrived from JLC

This is different from rusefi/alphax-2chan#47 since no USB power surge and a number of LEDs are ON, just no DFU

[rusefillc]

With USB power, 3v regulator gets 3.6v input instead of expected 4.8v input

with 3.6v input 3v generator outputs about 0.1v

[rusefillc]

keweisi usb detector says 1.6A

hottest area SEEMS to be between MCU module and VR module but hard to say with more precision :( i think back side gets cooler when I touch it, i take all the heat?

[rusefillc]

3v regulator U101 seemed like the hottest part

I've removed U101 and consumption went down to 0.17A

[rusefillc]

with U101 removed 3v to ground beeps, seems to be about 1 ohm

[rusefillc]

found issue it was similar to Harley defect

root cause lack of automated validation andreika-git/hellen-one#152

[rusefillc]

it was a gerber issues with a via under C461 - board is alive with minor grinding

Q: how happy is this ECU going to be without C461?

[rusefillc]

gerber issue around Ign fixed by 38b9e8f

[rusefillc]

three cuts total
