I had a ratty pair of jumper wires that I put together many years ago. I finally built these today. Don't get me wrong, the old ones still worked. I just wanted to make them even more convenient to use and store. Here's how I made 'em:

• 14 gauge "Primary Wire". $9 for a 25ft spool
• 4 alligator clips (I still call 'em "Roach Clips" even though I haven't used that stuff in over 20 years) are $3.99 box of 6
• 3/16" Heatshrink tubing. Cheap.
• Crimping tool or pair of pliers (crimping tool is easier)
• I started by cutting 2 lengths of wire 4ft long (that just seems to be the most useful size. Make 'em as long or short as you want.)
• Working one end at a time, strip off 1/2" of insulation.
• Crimp on the alligator clip.
• Slip the heat shrink tubing as far up the clip as possible (I used 6" to give some strain relief.)
  Shrink the tubing.
• Before starting on the other end of the wire, slip another piece of the heatshrink tubing over the wire.
• Repeat for all four ends.

To keep it tidy I used a couple pieces of Velcro to wrap the wire into a nice little bundle. The Velcro can also serve to hold the wire(s) in place when being used. For example, if I'm running it from battery positive to coil positive, it's way longer than it needs to be, and is dangling in front of the screen protecting the cooling fan. I don't like wires just dangling around, so I'd use the Velcro to bundle it up a bit and attach it to the aircleaner stand leaving just enough slack to keep it from yanking free while driving.

Now it goes in my toolbag replacing the ratty wad of wire that I've been keeping.

Which brings me to my next item...

So when shopping for a digital camera, those are the things you want when using it for your bus.

Megapixels aren't important. Most cameras are at least 3mp now which is adequate for an 8x10" print to use as a reference when reassembling something.

Zoom is important to help isolate what you're photographing parts installed in the bus. And a "fixed focus" lens is useless.

Macro mode is probably the most important item here for use with the bus. Most things you'll be photographing are smaller than your hand. And cameras without a macro mode cannot fill the frame with something that small. Something the size of a human face is the closest they get. My Olumpus, focussing down to 0.8", gets great shots of cracks in vacuum hose or part numbers stamped in door handles.

Removable media is necessary because even if the camera comes with a bit of internal memory, you don't want to have to keep running in the house to download the pictures because the memory is full. Get the largest you can afford. I use a 512 xD card as my main card. At the highest JPG setting I still get over a hundred shots. I dislike xD and Memory Stick because they are proprietary, though both Sony and Olympus have licensed the technology to other companies so they can make clones. I prefer Compact Flash because it is an open standard, but few if any inexpensive cameras use it. Nearly all digital SLRs do though.

Why a focus assit light is necessary: I'm under the bus. It's dark. I need a pic of the nipple on the fuel pressure regulator. I whip out the SP-320 and point it in the general direction of the FPR. Red light comes on and I can see the FPR now in the camera's LCD. Camera's green light comes on telling me it's got focus and I take the photo. Sometimes it picks something odd to focus on so it takes a couple shots. But now I have a great shot of the FPR's nipple. (Like Krusty the Clown, it's got 3 of 'em.)
