That's the brand of spanner I've been looking for for the last week!!! I have some somewhere...but where are they?  :-[
I know a few people I could give one to, but the 'gesture' may well 'go over their head'  ;D  ::)  :o

Cheers Scott

What is the benefit of it being double ended. ?

On the right track Scott in the fuel test, but not moisture but a flash test, here's the instructions on the inner door.

I've had this in my shed for many years and I only think I know what it is for and that is to test the house wiring in a house that has the wires running through metal conduit. The meter is a bit sad as it doesn't go back to zero but there is a slight tingle that comes through the wires when you crank it. There is a little red light that lights up if you crank it up a bit.

Hello John
That is an old hand cranked Megger and is indeed used for testing insulation around wires, in motors etc and is also used for testing to see if a wire is continuous or not (ie broken or bad connection in the middle). That one was usually used on 240V single phase type wiring, motors etc and when you do the insulation test about 500V is pumped into the circuit. A more powerful instrument was used on 415V wiring, motors etc.  About 1000V is used on 415V or 3 phase wiring etc
We were still using those mongrel things into the early 80's and when we got some press button ones we thought we were made.
The testing can only be done on dead circuits (no power) and that light is more then likely an indicator that lets you know if there is power in the circuit or not. Hopefully not.
Another apprentice I was working with hit the test button when the circuit had power in it once. Blew the begeesus out of the meter it did. It was so funny ;D
Megger is only a brand of meter but the industry uses Megger (for the instrument) or megged (as a process) as jargon.
The outer scale measures in million of ohms (megohms) and the inner scale is in ohms. For insulation you want to see infinity or close to it (the sideways 8 near 50 Mohm), if the reading is below 1 megohm then something is bad. Really, really bad. And for continuity you want as close to zero as possible. Anything over 3 ohm is really, really bad.

All of the above is very general information for those with no knowledge on meggers and their use. If you want to get more precise on the above info  then please do so.

Cheers Scott
PS: the press button ones were great at TAFE when you wired up the autosparky's chair and table and hit the button when he went to sleep. The tables had a really nice aluminium strip around the outside which made a great zappy point with arms and bellies.
In those days autosparky dudes and my type of sparky bonehead did the same first year at TAFE.

Hello Ian.
Temperature control? I don't know for certain but my guess would be temperature control/thermostat.
Someone may well know exactly why 4 pins.

Cheers Scott

Just by looking at the plug and spotting the horizontal pin I thought POMMY but the 4th pin threw that out the window.
