it's called a resistive connection.....not unlike the one that occurs on the 2 wire harness running from the generator, up to the main harness, near/behind the battery box....
if you have symptoms of this now, better check that connector.... it has a habit of melting, from the same resistive syndrome.
un plug/replug repetitively, or scrub the terminals if you can remove them from the plastic holders. these melt regularly, without warning, when farkles are run continuously
just a warning.
I'm sure we will hear about it someday.
