I found something.
The performance kit new power supply is 24V (the old one was 30 V) so the 30 V on SUBD15 is probably wrong and reset level is false (maybe too close to the limit due to a resistor divider). I measured 1.46 V when reset is pressed.
Could someone from Stepcraft check that ?
In France, this configuration is illegal due to the safety issue !!!

It's a safety issue without any response from Stepcraft...
Could someone at Stepcraft can check the schematics please ? If you have no time, could I have access to the small board schematics (I can sign a NDA) to propose a quick fix for users ?
