4 is not the correct answer. It's not that simple. Not helpful. I never said 4!! Did you get your English A-level from the same place as your Physics A-level?? Cuz clearly your can't read or do physics haha if you read back [mention]Joeman[/mention] I said 4. P=IV and IV= 4 in roman numerals. need to study Latin next

When i was doing my ONC many years ago we had to do electrical and mechanical engineering. I got higher marks in the first year mechanical exams than the electrical (and i am supposed to be an electrical engineer)

Last word on the subject before the MODS close us down. Transformers do not work with DC only AC. Just saying

Possible or the quality of the components so they last longer.

My fault. P=IV = 4 4 in roman numerals =IV. but my humour is obviously not appreciated

[mention]Baloo[/mention] on many items the input and the output ratings are shown on the devices. But see here http://www.mobilitysmart.cc/parts-spares-c-106/battery-chargers.html second item. (i rest my case)

I have a mains version of the charger in the shed. keep meaning to disassemble it and see if it can be utilised as a 12v charger. But [mention]Joeman[/mention] why does P=4

Without knowing the efficiency of the unit, how long is a piece of string. But....... the out put of the unit in watts (power) is watts = V x A w = 24 x 2 = 48 watts. so ignoring efficiency and other losses the 12 volt battery need to supply 48 watts. using the same formula so 48 = 12 x A 48 / 12 = Amps = 4. ball park figure depending on efficiency say 5 Amps best guess.

Snapjack won't work with a single sided swingarm you spotted my deliberate error. Doh!

I've seen a bodge using bricks and a lump of wood but I thought [mention]Lateralus[/mention] would like something in keeping with his new bike. But at the costs be better off with a centre stand

there is always this http://www.bikermart.co.uk/proddetail.asp?prod=PDSSNPJCK

Well done Jack

Bluetooth nominal range is about 10 metres and will pass through several brick walls easily so a sprinter van will not interfere with the signal, most bike intercom units easily exceed that. Scala units quote approx 1 mile.

You will need to change the frequency crystal in the transmitter and receiver. They come as a matched tx and Rx pair. But 27mhz are available as fm and am. The crystal is probably the metal can in the lower picture top left. See if the frequency is on it. Also check out the links below. This link shows the available frequencies for 27mhz http://www.ukrcc.org/27mhz.html http://www.blacksmithproducts.co.uk/rccrystal.asp HTH

Well done

Well done [mention]mas101[/mention] . And in a way it is good you do not feel "that" confident as you won' t be tempted into running before you can walk. Now take it easy get out when you can and enjoy the ride. You have passed the test and proved you are safe to be let lose, but now the learning really starts. So have fun.

Just to upset every one, for some electronic devices, in this case proximity switches the supplier in the data sheets does list the "LEAKAGE CURRENT". this is the amount of current that will flow in the circuit when the device is effectively OFF. https://www.ifm.com/products/uk/ds/IF6044.htm This is important in my line as these are often connected to Programmable Logic Controllers and if the leakage is too high the controller can not tell when the device is either on or off, and so will not control! For this reason only i used Baloo's analogy so none electrical peoples understand what we are trying to say. But the leakage current doesnt fall out of the end of the wire, it produces heat in the component as a byproduct of keeping the electronics in a standby condition.

Now look what you've done [mention]Mgrhiki[/mention] .

Keep meaning to get one of those.

That's nice. Always wanted one as its a similar styling to the GPX750 I had. Have to agree with Hoggs though. It is the wrong colour should be BLACK.

Edit forgot to post link http://www.bigmessowires.com/2016/01/28/standby-current-of-a-usb-car-charger/

As said in my earlier posts re the 240 volt domestic socket outlets with a USB charge, some manufacturers provide a figure for the power consumed in Watts when there are NO items connected. and as others have said electronic used to step down a voltage consume power all the time they are connected [mention]Baloo[/mention] like your leaking pipe. As the power loss is relatively low the amount of heat generated will also be low and probably not noticeable. So in the general scheme of thing it is unlikely to run down your battery. I found this where someone has already done the tests on a USB convertor. the current draw on the one he tested is a bit high as it has a LED to show it is on. But neverthe less the bottom line is unless it has a physical switch it will draw current but not enough to worry the battery. Even so I would power it from ignition controlled supply.

Can't find any data on these, but unless there is a physical switch the USB will always be on and draw a small amount of current. That will vary depending on the efficiency of the unit. Also a larger capacity battery will take longer to run down so in general use it should be ok, though I feed mine through a relay ignition controlled. Looking at other devices with USB's embedded, eg a 230 volt socket, these give a power rating of 0.23 watts consumed with Nothing connected. A side light is 5 watts.

I would bleed the brakes as a matter of course. I may even flush the lines until new fluid fills the lines as the old fluid may have got contaminated with water if the bike has been outside and the fluid open to the air for long.
