Hello,
Since they are sending my dead unit back, I will try and diagnose the sequence path of turn on.? I tried to manually key the main relay and that worked, but still no turn on.? So there has to be a sequence failure.? ? Looking at the schematic, there are way too many paths to trace out without knowing the correct path.? I have no problem with doing what ever is necessary to have the radio on all of the time power is applied, so looking for help on that.? There is nothing in the service manual for trouble shooting a no turn on problem.
