If a sensor is disconnected and ign turned on, the sensors "live feed" wire gets nearly 12v then drops to zero, as the fuel priming system works and then turns off.
If sersors all ok and connected ( i made a pair of test wires fitted between the wiring plug and the sensors socket pins, with a central bear section to connect the dmm to ) the live feed reaches battery voltage and stays there, even with engine running, and the abs light goes out after about 3 seconds.
More to come ...............as making rear subframe support blocks so can repair/paint rear jacking points and safety first rear wheels off and rotate wheel flanges to test sensor output and compare with the rest, need to set up scope form this as dmm results not conclusive.
