Introduction: Replacing Multimeter Test Lead
This is my first Instructable...Be kind or not
(Disclaimer: I didn't check every Instructable to determine if this has already been presented (there's just too darn many). If this is a repeat, I apologize.)
Some time ago a test lead on my el cheapo multimeter came off and was subsequently lost. Using the frayed ends of the lead wire worked, but not worth a hoot.
I visited our local Radio Shack and a couple of other shops to find a replacement lead but the cheapest I could find was $6.95 (US) for a pair; I could have replaced the whole thing for that.
Step 1: Step One
This is a pretty basic job requiring minimal skills, materials and tools.
A 6 penny finish nail, an old pen barrel sans ink "tube," soldering iron and solder (not shown), a bit of heat-shrink tubing, an X-Acto knife (or substitute) (not shown either) and our favorite, a hot glue gun and glue (also not shown).
I measured the ink barrel against the non-broken test lead for length then cut the barrel to length (measured from the tip). Save the cut-off end of the barrel as this will make good filler in your extra parts box.
Step 2: Step Two
After exposing about an inch (2.5 cm) of the wire I made a quick wrap around the head end of the finish nail and soldered them together.
Step 3: Step C
After the new lead tip cooled, (its now graduated from being a simple nail to an integral part of a precision instrument), I slid on the heat-shrink tubing that will cover the to-be-glued end and then popped the newly tipped wire lead down into the pen barrel letting about 3/4" (1.75 cm) of the once lowly nail protrude through the pen barrel tip.
I then hot glued around the wire end, filling up some of the ink barrel. I also shot a small dab of hot glue around where the lead protruded
Step 4: Step Last
And that's it.
If I had them, I would have used a red pen and red heat-shrink tubing. But since I had neither I'll just have to live with it.
Total cost: $0.00 (US) as I had everything already...I'll bet you do too.
