Title: TACHO
Post by: Ollie on July 24, 2006, 12:36:41
Me again:-)
I have a Tachometer from http://www.lowtension.com As you can see, the website is no longer active.

Now, when I bought this some years ago, I never new what a TD5 was, so perhaps I have purchased in error :oops: , nonetheless, my question is thus;

Will a '333.TD5  Land Rover Tachometer' from Lowtension work on my 300TDi :?:
It was supplied with fitting instructions and a wire connector to place within the Alternator wiring plug, one assumes from this it can :?:

Cheers
Ollie

When Low Tension used to list there gauges in eBay they appeared to be universal.

 The fact that it it's supplied with alternator fitting instructions  I’d imagine it would work.

Just done a quick Google and got the instructions that used to be on the lowtension site.

The tachometer output from the Td5 ECU is very low - even measuring with an oscilloscope the signal is small. We have boosted the DC offset to the standard VDO tachometer to enable it to function in the same way as the original equipment tachometer.


 Looking at this I would have thought it would work but read wrong???? maybe someone with better micro electronics knowledge can give a definitive answer.

Full instructions are here http://www.web-rover.co.uk/nav.php?p=td5kb/vdotacho

Thanks for all the advice chaps, as Colin states, it's not that difficult and was pleasantly surprised it worked first time.

 :idea:  I had to set the potentiometer to it's minimum setting with all the dip switches off for it to match the 750rpm.

Thanks again,
Ollie

I have one further question;

At 60mph, my tacho reads 3000rpm, is this right :?:

Cheers

Depends on you’re gearing and tyre setup.  What tyres are you running?

 Mine 200TDi dose 3000rpm at 50MPh.


That avatar is verry distracting..... hypnotic even  :wink:

I'm running Standard setup, General Grabbers 235x85 16.
3000rpm at 50mph sounds a little high?

Like the avitar eh, me too :(stoopid):

Actually, No, a Tachometer is a rev counter. There is also a second kind of Tacho, called a Tachograph That is used in HGVs to monitor speed. It works by projecting a laser onto a round disk, with time and speed printed on it.

unless you have the needle type that draws on the disc, and it monitors working hours mainly
