| + | [title] Measure which of the IGBTs is faulty |
|---|---|
| + | [* black] Measuring with a multimeter in the 'diode' mode revealed that the left IGBT (the GT60N321) had indeed given up the ghost: collector and emitter were diverted. |
| + | [* black] To be sure that this was not a side effect of the surrounding electronics, I desoldered the IGBT pins from the PCB with a tin sucker, and then measured again. The IGBT was indeed found to be defective. |
