>If you have more votage at the post then at the cable clamp (vise versa for >ground cable), then there's a votage drop across the connection. >Ray - - - - - - which is the most reliable way to check for bad connections or a cable/wire in bad condition. An ohmmeter passes a very low level voltage/current through a circuit and looks at the resultant voltage drop which comes up as ohms resistance. Testing in this manner will not produce meaningful results. The best way to evaluate a circuit is under load and look at impressed voltage and voltage drop (and in the starter circuit testing situation, the voltage drops across the individual items in the circuit on the pos and neg sides of the battery). Incremental allowable voltage drop is a case by case situation but the lower the better would be a good rule of thumb. Warren Anderson Sedona,AZ
