Hi - I need some help and advice please regarding the functions of the electrical sensors on the KV engine .
The photo shows the area of interest !
There are two temperature sensors on top and below the coolant elbow attached to the head.
One on the top has two wires - the one below a single brown wire. What is the function of each ? I have replaced both but my temperature gauge still doesn't work ( despite re soldering the dash instrument panel ).
And the red overheat symbol on the dash illuminates very quickly - but the fan works and the engine doesnt seem to overheat.
Then - in the picture there is a spare plastic plug 2 wire brown and red - I cant find any purpose for this ?
And then just visible below the warm up valve there are 2 single wire sensors screwed into the block - purpose of these ?
I have spent some time trying to bottom out the non working temp gauge - even a dash swap didnt give a result so now suspecting a wiring / sensor fault .
Thanks !
