I have attached a schematic for my electric fuel pump circuit and any opinions are welcome. However, this post is not about the circuit by how I drew it.

I want to document my wiring so I don’t have to remember everything if I ever need to work on it or get a bug somewhere. I have looked for circuit drawing diagram software and found it complicated, confusing and expensive. I think I have found a way to do it pretty fast with what came on my computer.

My internet has been down for several days and over my morning coffee I drew a bunch of symbols in Microsoft Paint. Each is saved as a separate file and all are drawn within a 1” X 1” box. I started a new file called “Electric Fuel Pump Circuit” and sized it to 8” X 11”. There is a button called “Past From” and I can go to the file where the symbols are located and just drop in what I need. Then it is just a matter of drawing straight lines to connect all of the terminals. After creating the symbol library I was able to create the circuit diagram surprisingly fast.

When I print it out I can three hole punch it and put it in a binder. When I wire the car I can jot down wire colors, gauge sizes, pin outs and make any changes in pencil and then update the computer file to reflect it.

The diagram skews a bit being resized from my picture trial site but not bad. What do you guys think? If anyone is interested I can e-mail you my symbol library. They are not exactly electrical code standard symbols but think of them as electrical symbols for dummies.

i like it. i can read it even though its not to "spec' like u said but its a good ez diagram that anyone can read and duplicate...actually it looks to spec to me .. simple like life should be

Thanks inFEKTid!

Here is another one I did for another guy here on the site. I am getting better at doing this to the point I can draw a schematic faster like this than I can on paper. The ability to go back and edit it is nice and storing it electronically I can share it with anyone that wants to see it. My main goal however is to better document my work.

I would think only one fuseable link in the hot to the alternator would be enough. You have one at both ends. The one nearest the battery is all you would need.

Yea, sometime my brain goes into overdrive. Let me explain. This is a street/strip car and sometime bad things happen on racetracks. I guess I can envision a scenario where (in a crash) the charge wire gets pinched and cut in two. One end falls away as an open circuit but the other end gets trapped and shorted to ground. If the side that gets trapped and shorted doesn’t have circuit protection we have a fire. There is a voltage source on both ends of that wire so I thought it best to protect both ends.
