Geiger Counter?
Discussion
Does anyone get a little geiger counter type noise from the dials? Its a constant little ticking when the car is in motion. I've narrowed it down to the rev counter because if I take my foot off the accelerator and dip the clutch it stops.
Its soooooooo irritating....
Factory had a look at it but couldn't suss it out.
Is there an easy way of disconnecting the power to the needle(s)? Presumably the digital counter could work independently?

Neil its the acc3elerator cable catching the pedal box cover and transmiting the engine noise into the cabin. They all do it in various degrees. To reduce it you can wrap the cable in a bit of foam and it will just it down imensely.
To be certain that is the reason, remove the pedal box cover and go for a drive, ticking gone then thats definately it.

Doesn't sound right but you've not been wrong every other time so I'll have a look

neil - you are a picky bu66er aren't you
Oi!
I just want it fixed before we go away in June as I don't fancy a drive down to Cornwall with that ticking. Its one of those small silly things that once you spend any amount of time in the car drives you insane. Its the TVR equivalent of chinese water torture
Your back safe and sound from skiing then Fishes? No broken bones?
Hang on, skiing Fishes? Does that make you Skate and Mrs Skate then?
I'll get me coat....

From a quick glance I can't see any cable - do you have to remove the box cover to get at it? I can see the adjuster screw (it probably has a technical name but I don't know it) - is that what you wrap in foam?
To answer my own question - its not the rev counter because if I rev the engine while standing still it doesn't do it.
I tried Fish’s solution, He is good!!!
I removed the pedal box cover and the noise stop, I tried using some foam around the accelerator cable and replace the cover, the noise was dulled down, but you could still hear it.
I am thinking about putting some spaces between the frame and the cover, so the cable is not touching the pedal box cover?
Anybody got any thoughts on me doing that!
I think if that doesn’t work I will drive around without it on.
I can’t believe what a crap design, that the cable is trapped between the cover and the frame, surely TVR could have design it better and why haven’t they change the design by now, everybody I have spoken to has got this problem.
I am also worried that the material that the cover is made of is working as a sound amplifier, has anybody heard of anybody making it out of any other material say like carbon fibre?

James here:
Conner the best way to dull down totaly if to drill the mounting holes larger on the pedal cover and fit grommets then reafix through the gromments also with foam round the cable. You will never totally get rid of the noise though its a part of the car.
I personnaly never bothered with the grommets as Mine was fine with the foam. I heard about it from someone who had it done at the factory. My T350c doesn't need it though it's fine.
HOpe that helps

Neil - did you ever get to the bottom of your noise?
It sounds suspiciously like what mine is doing. I took the pedal box cover off tonight and the throttle cable had been rubbing, now insulated with foam/gaffer tape. However, putting it all back together, starting the engine and touching the throttle with my head in the footwell and the noise is still there.
On my car it's a kind of intermittent chirping sound like metal rubbing on metal. Not rev related (except it doesn't do it at tickover). Since I've now proved it does it when the car isn't moving, but the throttle is pressed then I think it must be something in the instrument binnacle. Annoying.

Nope. I too removed the pedal box cover but (contrary to suggestion) the noise did not go away.
Glad you reminded me as I'd forgotten I was going to do more testing on this. My idea was to undo the instrument pod and disconnect the ribon cables then drive the car (somewhere safe!) and see if the noise goes away. Its pretty easy to remove the instruments but just make sure you mark up the ribbon cables as there's 3 or 4 with the same connector - wouldn't want to get them mixed up!

Thanks Neil. I was thinking the same thing overnight. I.e. disconnect the dials and see what happens. Looking at the dash it appears there are two bolts to remove allowing me to take the top of the pod off after which I guess I'll be able to access the back of the pod. Might have a bash this weekend.
