Gauge sender reading high
Discussion
Hi Folks… been having trouble with my temp gauge…
was working fine until one morning I noticed it was reading about 10 deg low at heat-up and when the fans came on… did various test and established it was the sender that was giving out an incorrect resistance… somehow it had increased and was therefore reading lower….
So, onto the web pages to get a new one … I ordered the bit Monday with guaranteed delivery for Wednesday… eventually it arrived as it was only posted on the Wednesday so I actually got the thing the following Monday!
! So scuppered a weekend we had planned in the car etc… But before fitting it I noticed it said AVO on the thing so called them to ask if it was OE part?....
Following a conversation where they apologised for the poor service, we also established that the one I’d been sent was for a Wedge and would not work in my Griff.. great
… So another one was sent out and arrived a couple of days latter…
Having fitted the new sender, I’m now seeing my fan’s come on at around 110 deg!! Which I know is not correct as I never have any overheating issues at all and the car runs up to about 90 deg max even on the hottest days…
So again I called them to ask if I had the correct part or if another mistake had been made… I was told that I did indeed have the correct part this time and what I now needed as a variable resistor to tune the thing in?... so off the guy went to find a part…
Having had no feedback I called this Monday to see what had happened ‘I’ll get on it straight away’ was the reply, so obviously nothing
So.. today I’m sat here with STILL NO REPLY!!… I’ve just called them again and been told I can get a 100 Ohm resistor from Maplin’s to get what I think is a faulty part working correctly…
Has anyone else had these issues with the senders and needed to fit a potentiometer in line to get the correct trim?

Hi John seems like your having some problems mate. I wouldn't have thought you would have to do a work around to get the temp gauge reading correctly. It seems very strange for a dealer to even suggest it.
If you haveto go down the line of fitting a pertentiometer then you also need to use a further temp gauge in order to set the thing up correctly or how else will you know is the reading you set it to is correct. Seems vey dodgy to me.

One of these John?
They list a genuine at £35!!! and a Lucas (but no dount crap) at £5. Should be plug and play. This is like getting hold of proper rotor arms?

Chris.. Yes.. not good... Id set it to 90 deg where I know the fan's come on at.. but as you say... why should you have to bother if it's a 'crap part' issue?? you back now??
FFG.. think thoes are ECU types but will look on the site... The one I need is a 'Cabonet' or something for the gauge.. it has a spade connection on the end...

No still in Florida sat by the pool lol. Will be back next Wednesday morning. I would try get hold the part tha FFG linked to see if that improves things and get a refund on the crap part.Chris

That is piss poor service if you ask me was working fine until one morning I noticed it was reading about 10 deg low at heat-up and when the fans came on… did various test and established it was the sender that was giving out an incorrect resistance… somehow it had increased and was therefore reading lower….

and why should you use a variable or fixed resistor? if your going to do this you may as well put the standard LR thermistor to use that's sitting idle in your inlet manifold and cost you a lot less and that's hardly ideal either(but more reliable) bloody jokers Edited by Simon says on Friday 10th June 22:10
Too right Simon... I was told it was a common issue.. but if not then indeed they are taking the P*ss !
.
Can you get the LR one working with the gauge?... I know it's in a better position but is it more accurate?.. not sure how the differant senders work... may bo one is linear and the other non-linear??

Here is a sample resistor found in-line on what ever version of TVR requires it....this is a sample for when the original fails (as they do over time, due to vibration I think) I have seen them often enough to have a sample in my tool box to copy and presume that I would have bought in 10 and replaced several as a precaution (I would need to search) for when they need to be replaced.

This is OE and attaches to the sender and the loom connects to the male ...as I said I seen enough of them to have an OE version in my toolbox (to copy)and would expect to have them in my wiring tray (where I keep silly things like that ..rather than my kitchen table!) it MUST relate to a version of dial, BUT IF I am working on temp wiring AND IT IS in the system then I would replace it as you do...

TVR beaver the resistor and LR sensor mod is not very linear but indicates the running temp which is all I need to see,if anything it registers early which is good as anything above my normal running temps would probably incorrectly register overheating that's all I need to know(calibrated to run in the centre of the gauge)I don't use my over-sensitive gauge as an indicator to know when I can hit the loud pedal I have common sense for that one 
been rock solid for 4 years like this.Simon says said:

Indeed.. I know my car is running okay... no problem... just want to get the gauge working right again... for that one time on the motorway when you get that small leak... and you can feel there is something not quite right... just gives you a better chance.

If not I'll get another sender and return this one....

let us know how you get on 
Called Power yesterday (not the original supplier) who kindly sent me out a unit to test... When it arrived I could tell it was the same manufacturer as the other new one I have... so stuck them both in water and measured their resistance thru a heating and cooling cycle:-
.
.
So they both work very close to each other.. so it's not a part issue... so may be it's a batch issue, or I am actualy running at 100 deg plus
(dont think so)
.
So back to Adrians resistor...
Adrian, I'm not sure from the pic.. but can you tell me the colours on the resistor... I've tried the ones I have and think a Brown / Green / Black (so 15 Ohm) would bring it back to a good reading.. but just interested what yours is? (middle 3 only) is it red / green / black???.. cheers...
