Yea but a warning light lets you know after its too hot, I want to know if I am starting to get it too hot.
@orttauq With the OE setup the gauge is 'set' in the centre, IOW it resists moving past that until the engine is very hot. When I did the mod (quite a few years back now), I found it important to make sure your soldering is good, and use a heat sink on the components. Mine now sits about a third of the way up when NOT and not at mid way.
I am wondering if setting it as you are, that you are not leaving enough room for the normal range of movement, i.e. it would read too hot when in reality it is still within operating spec?
