T&T: Debugging an electrical problem

[Greg Bradley]

I am a bit stumped and was hoping someone could help me out.  We just
bought a 44' Thompson Trawler in Ft. Myers, FL about 2 months ago.  We
have successfully moved the boat from Ft. Myers to Kentucky Lake to sit
out hurricane season this year.  Now that we are sitting at our dock on
Kentucky Lake, I'm experiencing an electric problem that we did not
have up to this point.

We we are on shore power (50A), we get enough power to power everything
on the boat (including dual air conditioners at the same time) except
the electric stove.  The electric stove will sort of power on, but the
burners never get very hot and the LED "On" light does not light.  This
is the first marina where we have had this issue.  The stove has worked
fine in other marinas on shore power.  If I switch to generator power,
the stove works just fine.  I have tried two shore side outlets (both
in the same box) and both inlets on the boat (one on each side).  There
are no other 50A shore side boxes close enough to reach.  My multimeter
doesn't have prongs long enough to measure voltage at the box.  I'm not
sure what else to test.

Is it my cable going bad?  Is it the shore side box that is bad?  Is it
the internal boat wiring having troubles?  

Thanks...
Greg...
