Edited: another fuel/temp gauge thread, but turns out the harness is melted together

With my key off and the temp sender wire terminal removed from the sender I measure 34 ohms from the terminal to battery negative.

Does this tell me anything? Should this value be close to 0?

Depends on what the engine temp is. I think I pictured the "gauge tester" earlier, let me look..........yeh back in post 5..........



So with engine cold, sender should be up around 70-75 ohms or more

23 is "mid scale" or somewhere "normal" so if it's only 34, it should have some running warmth in it, warm enough to run the heater but less than "full normal" temp
