A week ago I emailed the manufacturer of my electrical buss to ask for help with the problem I was having.  The problem was that the radios and engine gauges were shutting down when the starter cable was connected to the battery.  I finally received an email today.  The tech correctly identified the source of my problem.  I am glad to know that had I not been able to locate the source of the problem myself this email would have pointed me in the right direction.  I am also glad that I now know it takes a week to get an answer from them.  I’ll adjust my expectations for next time.
