I have not seen any for Webers on the Cross-Flow Renault.
In theory I can make almost anything the VMC would have done on my manual machine, just much more slowly.
The VMC is still a possibility if I can raise funds again.

Garage / Re: How Does a Voltage Stabilizer Work?

This is interesting - I have just been along this journey. Couple of days back I posted "Dilkris Update - Back at it!" (but I put it in 'Technical Articles' which was probably wrong) - anyway it was about me starting the engine finally after some time away from the project. 
I wired up a temporary temp gauge circuit,(without the voltage regulator), and upon the engine running it was showing 130 degrees - I then realized that this 'magic cube' was not an option as it does, amongst other things it seems, reduce voltage to the temperature and fuel gauges to 10V.
I have now installed it, (original item - see pics), and temperature now stabilizes at just over 90 degrees.
If you need any more readings please let me know as it is presently very accessible. 
Also in researching this component on line - (it was made by Smiths Motor Accessories BR1311/00) - it seems that how it is mounted is important to it's operation - ie: it appears it can only be mounted one way - please don't ask me why - I followed the instruction and it works...  :confused:
Please refer photo of BR1307-00NEG which I assume super cedes the original - read description

Yeah, it appears that your stabilizers are toast but it's curious that your new one is since I believe all the new ones are solid-state which should be much more reliable than the old ones (I believe they were electro-mechanical but I think the articles I posted and mentioned explain that pretty well). Anyway, your new one is clearly busted and you should send it back or just try again with another.

There is an article on building your own if you want to go that route (http://lotus-europa.com/manuals/misc/electrical/vregulator.gif). I think the instructions in that article were published before the solid state stabilizers were commercially available but from what I can tell, the instructions tell you how to make what you get when you buy a commercially available stabilizer.

In general, I believe the voltage stabilizer is designed provide a stable (max?) voltage of 10v. Since I’ve already exceeded my understanding this subject, I’ll refer you to an article that explains it better than I: http://lotus-europa.com/manuals/misc/electrical/gauges.html

Be sure to check out the link that explains how a “Lotus gauge works.”

Thanks for that information. A stable +10v comes out of the I terminal on neither stabilizer.

I took both stabilizers into the garage and plugged them into a charging battery.

The voltage going in was around 13.5v.

On the old stabilizer, the voltage coming out at the I terminal fluctuated repeatedly from 12.1v down to 0 then back up to 12.1v at around a 1 second cycle.

On the new stabilizer there was 0v output all the time at the I terminal.

Garage / How Does a Voltage Stabilizer Work?

I have no reading on either my fuel gauge or my water temperature gauge.

My first thoughts were the voltage stabilizer is not working.

I bought a new one, looked up how to wire it up. B = battery or ignition dark green wire, I = instruments = light green 2 wires, earth the casing.

Still nothing on either gauge.

I shorted out the dark green and light green wires and the temperature gauge started climbing.

I tested the voltage in at 12.5v and the voltage out was around 4v. I connected up the old voltage stabilizer and the voltage out was around 12.5V but neither gauge worked.

I am confused.

I can understand the fuel sender gauge might rusted up and giving no reading, but I cannot understand how the water temperature gauge works with ignition voltage, but does not work using the voltage from the I side of the stabilizer.

This means the plan is not to disassemble the whole car but to do what's needed whilst trying to get it back to the road asap.

 :FUNNY: We all tried that .....you'll end doing a full rebuild.. !!  :FUNNY: 
Good luck, welcome, and keep us posted on the journey.

For myself I am unhappy with the available air boxes and despise plastic.
Thinking aluminum base and fiberglass cover.
The machine can carve aluminum very well, steel runs too, just slower.


Would be happy to see the outcome of this - I need one. TCS original airboxes do occasionally come on the market but they demand serious money, proportionally they must be up there with ash trays.  :FUNNY:
In my ignorance though I cannot see how you would (economically) machine an aluminum base. 
I am preparing to make one from scratch - but I know its going to be a saga. :(
