Hello,
We just acquired a 95 F-350 at work. Part of my responsibilities is to do maintenance on all of the equipment. From heavy equipment to the boss's car. I am familiar with some of the basics of the Ford 7.3's. We have a couple of them already. I have been googling on several of the problems I have found so far. One that I have not found any info on is this.
The Glow plug relay stays on all the time. On the dash, the "wait to start" light comes on and goes off after a few seconds like it should. However the relay stays energized. The control wire is always hot. (We checked the relay and it isn't welded closed.) I have pulled the relays out on the fuse block on the drivers side and the relay turns off as it should. I don't have a wiring diagram of the motor so I don't know where the light in the dash and the relay get their power from. Has anyone run into this before? Is there a diagram of the wiring that is available on the internet? If we have to, I will put a manual push button in the cab for the glow plugs, but if its not too expensive, would prefer to fix it right. Tnx in advance, martin
