all righty then ! you guys have "learned me" something new. now, if i can just retain it ! i think more and more about trying that "brain medicine in pill form" they sell on late nite TV.
so now, using the 74/23/10 chart, if i touch the negative [black] probe [of my digital ohm meter] to the base of the sending unit that is immersed in the coolant, and touch the positive [red] lead to the signal wire end of the sending unit, it should read close to 73 ohms at room temperature, correct ? my main goal in all of this, is to weed out possible generic sending units from factory chrysler sending units.
thanks guys ! you have been very patient with this old geezer !
