Strat + humbuckers constant hum

[Snowgal]

Just finished putting Everything Axe humbuckers in a strat with 5 way switch, 2 tone, 1 volume. When tone knobs are turned all the way down, zero hum. If tone turned up I get a hum. I’ve used multi-meter to ensure everything is ground. Any idea about what I might have done wrong?

Wiring the output jack backwards can cause constant hum.

Might help to share a picture of the wiring...

Tone knobs turned down tends to roll off most frequencies that hum consists of. I would also try a different location in the building to see if that helps. But certainly post pics, too.
