John,
To echo David... Have you inspected the wire? I had a very similar issue
recently. had to oil switch replaced, panel checked.
Turns out, the wire was touching the engine block somewhere, and it had
melted and was causing inconsistent flickering, and buzzing. Some new wire
and a zip tie sorted the issue.!
good luck :)
