Testing the DCDC output with the replaced resistor (R8)
Test 1: Replaced resistor
...
no resistance from TR to HV GND
Voltage output is slightly higher, around 10.7V at 60V input
Test 3: Replaced Q2
Same conditions: input voltage 60V
Same output voltage: ~10.7V
Suspected leg 2 of Q2 is not properly connected
when checking conductivity leg 1 & 3 were good
