Fused Jumper Wire with On/Off switch...

[artguy]

Hopefully this will help those newer do-it-yourselfers:

While doing some recent fuel pump work I was reading in the Bentley about the testing procedures and ran across the mention, and the need, to have a Fused Jumper Wire with an On/Off switch.

So I hit five local auto parts stores, RadioShack, Sears, and a local electrical contractor supply store looking for one.
I got a blank stare each time I asked.

So I figured it can't be that difficult, so I went about making my own and here's the result:

The whole thing cost about $10 US, but it took a bit of time running to different stores to get the different parts.
Here is the Detailed explanation with what part is what:

I wish I could handle a PC so good to make such nice instructions.
Great diagram, a picture is worth more than 1000 words sometimes.
Thanks!

Its a great diagram, you should write repair manuals.

Anyways, why would you want a switch on a fuse circuit? I cannot think of any reason why you would want to shut down an entire circuit at once?

As Bentley's states..."To avoid fuse/relay panel damage from repeated connecting and disconnecting, also include a toggle switch."

In my case, testing fuel pump issues, you pull the fuel pump relay and plug the jumper into the slots for terminals #30 and #87. With the switch you can control the test better and not engage the pump test until you're ready.

I'm a creative director at an ad agency so I make images and layouts on a regular basis...so I can feed the kids and repair the bimmers. :D

I'm just glad to be able to use the skills to help out here and contribute.
