When testing the compressor with a trailer attached, must the trailer supply valve be closed?

True
False

The correct answer is: True

The trailer supply valve must be closed when testing the compressor with a trailer attached because it prevents any extra air from entering the system. This ensures that you are testing the compressor's ability to supply air to the trailer and not any potential leaks or issues with the trailer's own air supply. Option B is incorrect because leaving the trailer supply valve open would impact the accuracy of the test and could potentially lead to false results. This valve must be closed in order to conduct a proper test.
