Temperature sender units

[Jon S]

Hi
My temperature gauge moves up and down constantly whilst driving. I m going to replace the sender unit as part of trying to fix the problem. I ve looked online for a replacement but they all have a different connection to mine. Mine has a threadedconection that a nut screws on to and holds a brass ring which is connected to the wire.

All the ones i ve sen have spade connector on them. Its no problem to change the connector to a spade connection but itu makes me wonder if its the right part. Can i fit any sender unit for a rover v8 efi? My car is an '88 350i

Thanks

Jon

Jon. I know its up above my knee on my 3000s but not sure on the wedge but I know that it can cause this problem if bad connection or faulty one of the others I am sure will know

not sure that the Wedges had such sophistication as a voltage regulator

I may be wrong but I think it must

My experience with voltage regulators in the past is that it affects all gauges, one going up while the other goes down. i don't believe there is one fitted to the wedge.
