Temp gauge trouble shooting

Trailtech do kits that are controlled with temp etc

@calum run it from the battery on a switch so I can choose when I use it

@jens-eskildsen sorry to be the one to tell you this, but for one, you have the fan blowing the radiator the wrong way, rendering it useless as soon as you start to move

secondly, pc fans are useless in vehicle application, they offer literally nowhere near the amount of airflow that moving even at 5mph provides. typically a PC is generating 150w of heat or less, thats 0.15kw, whereas a bike such as this is making hundreds of times more heat.

you need an automotive fan to make an ounce of difference

wow hahahahahahaha
@declan it probably the same one for other motors so could pick one up for £5 ish maybe measure the thread and ask sellers ect don't worry about the connection that's easy fix you probably have some old connector around

[Calum]

@tunertom You can pull air through the radiator no problems.

[finnerz89]

@tunertom the fan on my triumph is behind the radiator, as is the one on my aprilia.

[Jens Eskildsen]

Tom, I know, as I said, it was a test to see if it would fit.
Its mounted on the right side tho, and its supposed to suck air, not blow it, so it pulls air through the radiator.

[declan]

@jens-eskildsen yeah in my mechanics course we were told that some fans suck air through the radiator fins and others blow it through guess it doesent really matter

[Jens Eskildsen]

Fan is protected a bit by fitting it on the backside

[declan]

@jens-eskildsen but it's harder to fit and gets in the way more and then you can't see it

[tunertom]

youve got the fan blowing towards the front of the bike... i didnt say it was in the wrong place i said its massively underpowered for application and its blowing the wrong way, its fighting the direction of the wind!

as you can see..

And I answered "I know that", and described in detail that it was only a testfitting.
I got it for free, and now have the wiring sorted for a proper fan, and know what dimension will fit.
Lets move along, shall we?

wouldnt a tape measure or an engineers rule, to measure the width of the radiator core not been sufficient to see what size of automotive fan you need, be better than bodging computer components onto it?

[declan]

@tunertom not really since I have neither of those but now I know the dimensions I need just in case I come across one

[Jens Eskildsen]

Norwp, I needed to make sure that I could physically mount it to the radiator aswell.
But thanks for your concern
