I cant get the temperature gauge to work properly on my Land Rover. My Series IIA has the 2.5l petrol defender engine. On the block there are 3 sensor terminals: 1. On the filter casing theres a terminal, connected to the oil pressure warning light, which works. 2. On the n/s/f of the block, at the top, just behind the thermostat housing, is a terminal in a flat topped sensor, held in by 3 bolts, which is connected to the temperature gauge. When the engine is cold the gauge shows cold, and a test light to the terminal doesnt light. As soon as the thermostat opens the gauge goes straight to hot, and the test light lights. 3. On the o/s/f of the block, at the side, near No 1 plug, is a brass hex with a terminal, not connected to anything. Test light = nothing, engine hot or cold. So, have I got a faulty gauge, a faulty sensor, or is something wired up wrong? Is one of these sensors for an oil pressure gauge? Im trying to sort out a thermostatic fan. Ive got a rad (from the Defender I assume) with a sensor/switch just below the top hose entry, which has 3 wires, black, red & white. I assume that red should be a +ve supply, black earth, and white should switch the fan (Ive used a relay), but I cant get it to work, and without the temp gauge working its hard to know whats going on. Can someone help please?
