I was looking around for a good ground to use for a WVO temp sending unit on my 82 300SD and everything I looked at read about 35 ohms to the NEG battery terminal. The meter and leads will zero out at 0.6 ohms..... the various points on the block and engine read about 0.7 ohms to various points on the chassis.

I don't seem to have any electrical issues, essentially everything works...... but I can't believe this is a normal reading.


Where does the NEG battery cable physically attach to the engine/chassis?
