While I was in our local auto shop buying some spare fuses i noticed a this great little 20 amp 12/24v test unit. It alows you to test the current draw on the circuit for the fuse you are having issues with or just want to see what your headlight, spots ect is drawing.At only $10.00 I thought i should give it a go. A whole lot cheaper than
a 20amp multimeter and This device just plugs in place of your fuse.
You need to make sure you place the fuse from the wedge socket you are
testing into the plugs fuse holder or NO FUSE PROTECTION. It wont work
with out it anyways. I used my resettable blade fuses.


All you do is remove the fuse and plug in the tester,Turn it on and start your bike..Read off the display. It will contiue to read any load you add on the circuit and can be left in place for watching the actual draw while in motion. It will also indicate polarity as well. I tested the current draw in a few sockets and it works well.
I think will be a useful fault finding tool.
High Beam

Spots with High beam

And the instrument/brake fuse socket.

wow ...a great tool alby ...and the price is right ....way cool

you could also do the same with a .1 ohm resistor (calibrated of corse ) and just measure the voltage drop across it = direct reading of amps to volts should be real easy + the extra decimal point .

but this tool is way cool ...all the work is done .....cheers ..

Nice one Alby, I've just ordered one from Maplins UK.
Cheers,
Paul.

Nice unit, also available in the UK: http://www.maplin.co.uk/automotive-current-tester-217879.
It doesn't seem to be available in North America

Even cheaper at the Farnell site.

Yes Inge, But their delivery/handling charge makes it £1 more expensive!
Paul.

Thanks Paul, then they`re not gonna be my first choice.

G'day Alby,the current tester is a great unit.After reading your post I hotfooted down to the local auto shop and bought one.The shop said they were a discontinued line because of poor sales.Cheers Tom

farnell ....hahahhahahah yourve got to be joking ....and no i havent seen the link .....(hides quietly in the corner)

Add a pair of lucar connectors with leads to croc clips and, hey ho, its a 'use anywhere' 20A ammeter.

Thanks again, Alby.

Paul.

Clever one, Paul.

paul, I had the same idea except I used a fuse wedge with clips on each end. same result.

They are available on Ebay.  Not quite as cheap, but still not bad.
