Installed a second chip also does not work
What am I doing wrong?
Voltage relative to S
D-315V
X - 1.7 V
C - 5.3 V
F-0 V
V-2.8V

Thank you in advance for your response

thanks, I'll try
Thank you very much, you helped me a lot
Hi,
Your Line sense resistors R6 and R8 seems to be too small at 15k, it should be at least 4Meg total. Just to be sure, also replace the part when you try powering up again with the new resistors.
