- I use the leads that come with the dvm. I also tried copper wire inserted into
- the coolant -- no difference. The only time I had an "off-the-wall" reading
- was when used some wire purchased in an auto parts store. :-)

- Try getting a hold of that SAE book I mentioned. It turns out that certain
- probe alloys will over-sensitize the test; that is, the corrosion protection
- may be marginal, but the test will suggest that the coolant must be changed.
- The book covers all this.
