Amongst other things today I took my rear height sensors off to swap them over.
It was useless as they appear to have been swapped already so the tracks were already worn. Anyhow i learnt some more about them that may benefit others in the future.
On the back of mine is the following writing
Colvern is still trading and can be found here http://www.abelectronic.com/electronic-products.html The current height sensor is at the bottom of that page.
My part number is CP17/413 and the 1k25M bit is the resistance value. The next 5 digits are the day and year 285th day of 1995. My other sensor was dated 1996 so both still the originals and quite well worn.I note that the part number has changed throughout the years CP17/414 CP17/417 and CP17/420 are the ones I have seen so far.
I have ordered two replacements today from Island 4x4 (£125 for two inc delivery) and will add more pictures when they arrive and try to do a write up on converting to the later type using the kit supplied.
