Dear Greg.
My resistance measurement comes and goes.... when it isn't .4 ohms it is about 2.4kohms... tapping the board makes it change.? I have gone back to the work bench and rechecked some solder joints... But so far I have not been able to locate the joint that is either shorting to to something or something internal in the board is shorting it out.? It is a 5 layer board and? may be having an internal short in there.?? With the type of construction that is very unlikely but may be possible.?? My original software load may have been compromised by the board shorting during the upload.? So I may try to manually redo it when the shorts are not there..? (neat trick if I can pull it off)? the first upload may have been interrupted.? Ludwig sent me so really good information that I didn't know existed on how this all works.? What I see is the 3.3 regulated is on the linear regulator and the 5V is High on the diagnostic but read 4.6 or 4.8 on my meter when I test it externally.? I am running on a 8V reduced voltage and going to stay that way until I can find the short on the 3.3v supply.... or at least get the 3.3V up on the? SMS power supply.?? Lots of things to check and a busy day today.?
Take care and have fun.?? Thanks for the hints.
