error the voltage will be much lower

Disconnect the positive supply from the
components to target the error cause.
The exception here is the F1 traction
controller which must remain
connected. One component overloads
the testing voltage due to internal short
circuit.
The testing voltage arises by charging
the internal capacitor batteries via a
resistor to the level of the control
