I would check the plug on the end of your power cord first.  First, disconnect for shorepower, see if the situation is normal on generator power.  If it is, the power cord (typically the plug) is the most likely candidate to be causing the problem.  It may require getting the plug off the cord and purchasing and installing a new one.  If you have the same issue on generator power, then the issue is in the transfer switch or in the coach itself.

NOTE: To keep from co-mingling issues, I have moved this post to a new thread.
