Bally, 1997hi all
working on a pin and booted with this error:
Check fuses 101 and 18, J127 and opto 12V supply/
Fuses are fine. checked with digital multimeter. Checked voltages on J127 and those are good. All leds are lit on powder driver board. checked voltages on J139-2 and 12V is there.
There is not 12 on the 7 opto switch board. There is continuity from J139-2.
I am stumped. Any suggestions?
Thanks
J139-2 has 12v, but opto board has no 12v on the grey/yellow wire on the opto board J3-1 or 2? Has to be a broken wire even if continuity checks ok. Maybe you do have 12v on the grey/yellow on the opto board, but power is being lost between there and the rest of the opto board from an open on the board. D1 diode could be open. Check for 12v on both ends.
