    Anyone ever had a problem like this. Or something close to it we think it might be the dash cluster. when we run the PTO and turn the rpms up as soon as you turn the headlights on the RPM shuts down. We started with the wires in the back of the truckmake sure everything had a good connection and was wired correctly. running lights turn on but turn signal and brake lights only work with the lights off shut off.
