First of all...did you knock the wires off the PTO itself at the shaft?....I know that @PA318Guy will see this and be able to tell you exactly what the problem is...he has that user name for a reason
affirm - voltage measured between the two leads of the connector to the PTO; when connected, measured voltage between the two wires heading directly into the PTO. will try to take a picture of what I'm measuring.Does the connector have both power AND ground with the pto switch on?
Thanks guys; the resistance is good; 3.8 ohms. here's pic.dave_r gave excellent advice to check the resistance of the PTO.
