Having problems with your 1997 Chevrolet Blazer ?
Voltage drop test
\015 How do I conduct th voltage drop test?\015
A voltage drop test is done using a DVOM. Set the meter to the DC voltage scale. Depending on the side of the cicuit you are on, place the positive lead on the most positive end of the cable.(closest to the positive terminal) and the negative on the other side of your cable/connection.Then exercise it. ( IE: Turn the headlight switch when checking voltage drop across the ground). The meter should read as close to zero volts as possible. (acceptable to rise up to 0.03v on the ground side) The reading you get is the amount that the cable or connection you are checking is drawing from your 12v source. You should do this to check for concerns in a circuit, so do not clean the connections until you perform the test.I hope this is helpful, if you need more info., drop me a line.
Go to the far end of the cable and make sure the voltage is the same as the other end, clean the cable ends first.
