Hi Trevor:
I am just in the process of hooking up my 4500/3500 engine sensor harness to the engine. Today I hooked up the oil temp/press and fuel pressure. The OT indicates logically as does the oil pressure (ambient temp and zero). But the fuel pressure changes from a "--" reading to an occasional "-2" reading. I thought I had a bad wire connection at the transducer and replaced the terminal ring. It still does this and doesn't seem to be a wiring problem. Is this normal (engine has never been run... no wings installed yet). Also the red bar is at the bottom of the indication when it shows "--" and "-2". Also the reading spools up and down when I disconnect the wire.
