the temperature guage on my 1900 watercooled reads very low.. I have shorted the sender cable to earth and get
full guage indication, I think i may have the wrong tranmitter fitted , can anyone give me the part number of
the correct sender unit please

Have you considered that you may have No middle in your thermostat, or that the one fitted may be jammed in the open position ?

Have you checked this before asking your question ?

There is a difference in the cooling system, the earlier model I believe had the thermostat mounted integral with the water pump housing, with a threaded sender.
Later models have the plastic thermostat housing and the temperature sender is held in with a clip.

im guessing its a early water sys, by the way you said you shorted it out to earth. Its not unusual for those early senders to be the incorrect one, supplied wrongly.

its also a commont problem that the single spade connector gets tarnished with heated on grime from the hot / cold temps it suffers, try a new shiney one after cleaning the brass of the sender contact up with a nail file?????
