The Mower Bench

The techies amongst you will probably know what this is, but it will probably be a mystery to many of you.

 

I was unaware of its existance, or purpose, for many years, but it is now an essential part of my toolkit.

 

Any ideas?

Going to have a guess at something to do with a battery?

I know but not saying. I get told off for telling too quick.

 

And no I won't say if anyone pm me.

Not seen one in 50 years of fitting but looks to be extending -ve battery terminal to hook on test leads,too much bare metal to be from the live side?

Nice one Rich, but will you be able to explain how it works when the time comes?

 

Not sure that I can.

Hi Barry Dc shunt used to measure amps etc that would require heavy test equipment , it allows a standard multimeter to measure values outside of its scale , that's how I interpret it anyway.

Not got one myself but used one years ago when I worked in the automotive sector

Hi Neil, welcome to the forum.

 

And, yes, it is a DC shunt.

 

It is invaluable for testing charging systems, discharge rates, starting current etc.

 

It works by having a set resistance of one milliohm between the two terminals.

As Ohms law states that 1volt will push 1amp through a resistance of 1 ohm, then we can use a Fluke set on millivolts to read as Amps between the two terminals.

 

This way we avoid high current when testing. Less sparks and blown instruments.

 

Connect the shunt to the negative battery terminal, and the negative battery lead to the shunt. All tests can then be made easily and safely.

Thanks for the welcome been lurking for sometime and finally decided to take the plunge I am a dealer / repairer myself so will probably be on this mower section a fair bit
