Hi everyone. Along with my head or head gasket problem I'm trying to diagnose why I have no power to the glow plugs, lights or horn. When you turn the key on the glow plug lamp illuminates but never goes out until you start the engine. It will eventually start without them on a normal day but I am getting zero volts to the power lead going to the glow plug connector. Also the high beam (blue) lamp is illuminated at the same time. It also goes out once you crank and start the motor. The brake lights work fine as well and the starter and stop solenoid. The cooling Fan comes on but I think it is coming on a little late, seems to get a bit too hot before it decides to run but it does eventually come on. Nothing obvious is jumping out. No damaged wire harness that I can see. Checked all the fuses and they all are good. If someone knows where to get a wiring diagram or whole service manual for reasonable let me know too. The kubota dealership here wants $130 for the book. Thanks in advance for any info or help.
