Good information again Larry! I did open up the mini USB connector and verified that the 8.2K resistor in the connector body itself was making intermittent connection to the pin (x) or numerically pin 4. To my chagrin, the gold contacts when exposed to full view did not appear to be anything but clean and proper! However, the issue will be resolved, I have ordered some 5 conductor mini USB to pigtail cables from Argent, and I will use one to set this aright.
I have damaged the Garmin cable beyond the point of returning it, and although I am disappointed that I had a faulty one, the excursion into mini USB education was worth it. Great resources here with your help and pictures and drawings in the Files section. When the cables arrive, I will then see if all of my problems are thus resolved <g>. 73, Dave KI4PSR --- In [email protected], "k7ybz" <k7...@...> wrote: > > Dave, > > The FMI cable is resold through Argent. It is a Garmin manufactured cable. I bought a batch of the cables for a bicycle event and had one DOA. I would say Garmin's QA has a little to be desired. I did have a spare and used that. I didn't replace it, but took it apart to find out what the story was but didn't find anything definite. > > Regardless, Scott may be able to do something for you. > > Larry > K7YBZ > > --- In [email protected], "Dave" dave@ wrote: > > > > Thanks again for the reply and information Larry, much appreciated. > > Unfortunately the problem is back a day after I installed everything in > > the car.
