Fuses Continuity

Check that the fuses upstream of the SCR contactor have continuity

Resistance Measurement

Perform a resistance test Ω with a multimeter on the XP terminals to check the resistance of the heating element.
Low values are correct for our resistances (5-10 Ohm).

SCR Led Status & Tightening Torque

Check first the LED status on the SCR to determine the type of problem

Check the stripping length and tightening torque of the SCR wiring to avoid connection problems
