Yeah it’s too low, so next port of call is finding out if you have a short to ground on any of your other primary rails and if so which one represents to the lowest resistance measurment, we’re doing this to narrow down the potential culprit.
Here’s the points I was reffering to earlier, you put your black probe on ground and your red probe at one of the highlighted coloured points, each of these points represents a different rail.
If your meter displays a value which is the exact same as the range at which it’s set then adjust the range on the dial until you get a real reading.
Note: the image is of a Switch Lite board but the points remain the same, the inductors (coloured highlights) are in a different package style but are ultimately the same.
