ACS712 will not measure load

ACS712 module will not measure 56 ma a/c @ 15.5v a/c. this was measured with a fluke muiltyimeter.

You can't measure AC current like that. Check this link for 1 scheme that works fairly well.

These hall sensor chips are not designed for low currents - they come in +/-5A, +/-12.5A and +/-25A
ranges if I recall right, and you’d expect maybe 1% error of full-scale, ie 50mA for the most sensitive one.
They produce a lot of noise as the hall effect is a weak effect.
