Where and what is the PWM exactly? Is it a simple IC or something else? Are there points I can measure with my multimeter? On the primary side of the inverter I have 3,2-5-ground-12,6 volt. Is this the right voltage? I can’t check a AC voltage over 600V. My display only lights up one time (when I regulate from zero to first dim regulation - software) or I plug out in the inverter? What now? Any ideas? thx
No one here has answered you question probably we’ve never heard of the PWM. It’s just not something we work with. As for AC voltages over 600v, your Mac runs on DC current. We’re not electrical engineers. Now if you explain what’s happening with your machine and its history we can probably help you determine which part has failed and how to get it running.
