My Source 4WRD II shorts out when installed onto a Source 4 ERS fixture body. You might not even know that it shorted out until you get an overtemp error after the lamp is emitting for a minute or few because the affected capacitor is part of the fan circuit and may only take out the fan voltage regulator.
Description/Explanation of Issue
During a point in manufacturing, there was an alternate capacitor that was used.
This capacitor was taller than the original, and made contact with the fixture body when installed.
If you come across this situation, please contact ETC Technical Services with the serial numbers of the affected units.
