testing tach out

self stim got 2.5v output and frequency

switched to 12v tach out got 3.3v FAILED?

rusefillc commented 2 years ago

in 12v mode I have 2.9 voltage across R47 D56 8.9v and 9.1v

rusefillc commented 2 years ago

R47 replaced with 470 ohm voltage across is 0.9v now

tach output 7.3v D56 10.9 and 11.1 D29 12.0 and 7.3v

with R46=470 and D1 removed we got 11.5v on tach out!
