Yes, I have tried both Pmags with the same results and tried turning them off one at a time as well with no change. I should double check, the capacitor value is .47uf 50V and a 500 ohm resistor. The diagram is not real clear for the capacitor value on my computer. I installed the filter at the pmag end. Is it possible it would work better at the AFS end. The other thing is they send a diode to change the pulse if needed to 5V, do you think using the diode and filter with the 5v input would be better? I hope to get time tommorrow to try and solve this again.
