Hi guys, I have not so expensive digital meter without clamps. If I try to find correct wires with coupler nearby

then I can check it but if the wire is in tight place and I need to test it I need to cut the wire to test but I do not want to cut it unless it is absolutely necessary. How do you find the correct wires without cutting them? Maybe T-taps to use ? with the digital meter without clamps ? Any better way to find, appreciated wtih any advise.

Use your wire cutters and gently hold the wire with them making sure not to cut it. A gentle squeeze will make contact with the wire underneath the shield. Place your test probe agianst the cutters. You need to make sure you don't touch any metal....

Personally, if time permits asking someone is probably is the best thing. This site is one of them. Getting good wiring diagram is also important. Otherwise a piercing probe is the best thing to use. Everything I have found is secondary.

Be careful whose advice you buy, but be patient with those who supply it. Finding wires -- posted image.

If you frequently need to probe unknown wires, something like this would be good- available from digikey and various other places.

I usually would just use a pin to make it through the insulation with the minimum amount of disturbance, but the insulation piercing test probe is a lot more finger-friendly..

This one is twice the price, but it's got nice extended tips to reach into a bundle, and you can just connect it to your meter with the banana jack-

Just slip the wire in and push to probe.

Dualsport,

Where do you get that thing?

I didn't realize that I've gotta have it until I saw it.

They've got them at Digikey.com, just search for "insulation piercing" and they should come up-
