Can anyone help make the graph for testing the rectifier a little more simple I do not understand what the readings should be for each leg and the numbers on my Z 8

[2015 Z Force 800 53/Trail EPS]

Dang this is the oddest test graph I have ever seen. I can't fully understand it..yet But I'll keep working on it. Go a head and set your meter to Ohms and test between 1,2 & 3 to the (-)neg terminal and see if you get these readings.

Ya it is very difficult to understand what they mean
