Answer
Hi R.J.
From here it sounds like the D/C circuit breaker in the lower end of the converter is being over loaded. And what you are seeing/hearing is the breaker, breaking and resetting. Could be a weak breaker or too much current flow or both.
Is this a magnetek 6300 series converter??. If so the breaker is replaceable, but I suspect something else is the cause. You'll need to have someone check the voltages a the converter output and charger.
