Have you tried with another ESC? It sounds like a broken phase wire, a dodgy solder joint, popped FET. Something with one phase not working. Given it's on all 3 motors, I'd suggest the ESC or joints are worth looking at.
I did use a multimeter, don't know any other way...I also checked the resistance with another working motor, an 1850 Kv on the Radjet - with the same sort of readings?
Anyway, I did resolder the joints on the HK Park250 and now it seems fine. Probably will be the same with the other, but these tiiny wires are a nightmare.
