Well, I promised a while ago that if I could get ahold of a program for drawing scematics I would make some quick troubleshooting diagrams for us all. I got Visio2000 and it seems to be adequate for this so I will start posting my schematics as I draw them. If no one is interested let me know and I'll just keep this to myself. Just thought that I might help.
First is the circuit that causes much head ach with the D-jet system. "Why is my fuel pump fuse blowing?" Usually it is because the Auxilary Air Valve is shorting to the block at the plug, but here are the other things involved. This is of the fuse/relay panel in the left engine compartment: B+ is the positive side of the battery. The pointy parts at the end of some of the lines are ground. Consider all grounds to be the same place and to be connected to the negative side of the battery through the cars body. Ask questions if you need clarification. Attached thumbnail(s) |

Before you get too far along, I'd like to point everyone to what I consider to be the finest home-brewed wiring diagram available:
Dave Hillman's 912 diagram Click on the layered PDF link. Wiring colors on the diagram help a lot. Having the layers allows you to only see the part of the system you're interested in. Dave has some info on how he created this diagram on the site. I know he started with the factory b & w wiring diagram and went to town. Any effort is, of course, appreciated (and perhaps we all need to pitch in on this and add it to the tech pages), but Dave's work is the best I've seen, and is a great target to shoot for. |
