Fitted a new Water temperature gauge to Matt's buggy as he didn't have a gauge. But the thread of the old sender (I think 5/8 18 found that in another forum) is completely different from the one with the gauge. Unfortunatley no converters came with it either. The gauge works, but the temperature goes up very quickly & reads over 100 when the engine clearly isn't.
So I put a meter across both senders at room temperature the new one is 1.755K ohm & in boiling water in a pan 0.145K ohm. The old one from the Mini engine read 0.771K ohm at room & 0.055K ohm at boiling. This explains why it reads high as the resistance is too low. Apart from getting an adaptor, is there any electronic way of fooling the gauge.
