Hi,
I am new to Land Rover, but I have bought a 1987 Land Rover 90 with a 200Tdi conversion that seems to work very well. Just 1 issue, the temp gauge needle hardly moves from cold when the engine is hot.
I have taken the connection from the sender unit straight to earth and and found that the needle only moves to half way between cold and red hot, I would expect it to go all the way into the red. Could this be a faulty gauge ?
Everything else seems to work fine including the fuel gauge which shares a common positive feed.
Any thoughts

if gauge doesnt move to high when wire is earthed ,gauge is poorly,unless it doesnt have 12v feed to it

Gauges normally run on less than 12v. I think regulators are set to 10 to allow for high usage and volt drop.

feed is from the fuse box which is 12v,series have a voltage regulator defenders dont

Rip your gauge out, and buy another one with a matching sending unit. Even a cheapo one made by TIM will do the job. A Durite or VDO will naturally be a better choice.

I'm in the middle of doing this myself just waiting for a local machine shop to make me an adaptor to screw into the thermostate housing and screw the matched sender into the adaptor, Durite gauge fitted but reads just like the std gauge atm till I get the adaptor made

Another vote for Durite stuff - very well made IME, and decent support too

Junk electrical gauge altogether and go for an old school mechanical gauge [Durite best, TIM ok] fiddle to fit but once done as near as damn it 100% reliable......................... £30.00 or so and peace of mind - good luck

+1 for durite, accurate and responsive enough you can see the thermostat opening.
