testing live wires

[tadders]

Hi guys, I'm after advise on checking live wires. Do I need a circuit tester or can I use the Electricians screwdriver I have, and if so how does it work. Many thanks

They do some very similar ones for auto electrics.... 12V lamp in a 1 1/4 x 1/4 inch fuse type body, the familiar spring... and a metal end cap with 4mm socket to connect the flying lead.

Mix up one of those in your tool kit if you're used to those neon screwdrivers and it won't be the 12V lamp that lights up when you pick up the wrong one when "testing" domestic electrics!

What do we reckon? about 20 Ohms when cold for that lamp? OUCH!

I have one of these, this type is actually very good for auto electrics I think

I think one of my head aches is coming on....

I love these wind-ups.

They make me smile.

This is a wind-up right?

I hope to hell that it is as well mate, but the chances are that it is not a wind up.
Very very scary.
