testing tach out
self stim got 2.5v output and frequency
switched to 12v tach out got 3.3v FAILED?
in 12v mode I have 2.9 voltage across R47 D56 8.9v and 9.1v
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!
another board, original R46 D1 removed tach output in 12v mode: 9.9v
rev C is a success
powers on!
