Apply power; if the breaker now holds, the tripler is shorted.
Also check the electrolytic capacitor and the rectifier diodes for shorts.
I have many modules for that chassis, if you should need any.

On sets where the trippler may be bad but no breaker tripping occurs the trippler can be checked by measuring the boost voltage with and without the trippler....if is is low with and normal without you know the trippler is done.
