Re: [APD] Problem with MH light
Unless you *know* the smoke wass not coming from the
ballast, I wouldn't want to start it without having a look
at the internals. If the transformer developed any shorted
windings and started smoking, the telltale odor is usually
hard to mistake for any other -- but it need not be strong.
I'd want to inspect for heat damage or spark marks from the
outlet throughout the circuit to the bulb socket.
Note: If the ballast is under warranty, opening it will
probably void the warranty!
