Smiths Tachometer

[S11A]

Actually, the following Autometer tach might be perfect, since it is specifically made for a diesel, and includes a trigger that is mounted to the alternator, thus eliminating the need for the Dakota Digital converter that would otherwise be needed for converting between the W or other signal to the signal a gasoline tach is expecting:

That last Autometer only goes to 5K, so it will not have the same scale as the the TR4 gauge I bought. I am now looking at a marine tach, and will post more details of that once I find out if it will work.

In the mean time, here is the diagram on how to wire a Delco alternator to provide a signal for the tach (i.e.- more or less the W terminal):

British Northwest Land Rover Co has something- don't think it's Smith's...but it looks good IMO. Here's a link to a pic:

Hope this is helpful.

Jay,

Thanks for the link to the photo. I think it is a Smiths...

Woops- you're right! I like the fact that it has the "red zone"- although I've never revved a rover engine anywhere near that! Not sure what the "proper" redline is for a stock 2.25L motor...maybe something to keep in mind if you're shooting for accuracy vs. appearance.

Apparently there was a real "Land Rover" tach...at least for a SIII...

Thanks Clive! It looks like the URL contains the word "pangolin", so I am guessing this is from Ike's site (or an older version thereof)?

From the looks of the screw next to it, I am guessing this is not one of the larger gauges, but probably the 52mm ones?

Might have to keep searching.

I looked into having a LR series replica one built by Smiths in Swansea (Wales, UK), now the Caerbont Gauge factory, and they will make one....for a price, of course!
