How To Do A Voltage Drop Test On A Battery. We will isolate the cause by testing out the individual parts of the circuit. But if there is a measurable voltage drop the meter will tell you what it is.
How To Perform a Tractor Electrics and Voltage Drop Test. 1 Connect the negative test lead of a Digital VoltOhm meter DVOM to the negative battery terminal. 1 With the voltmeter connected to battery and key and engine off record a base voltage reading.
This is because a voltage drop test is the best way to find resistance in a high current circuit.
Connect the positive test. Your trouble point will be the previous one to this point. The battery voltage test is use d on maintenance-free batteries because these batteries do not have caps that can be removed for testing with a hydrometer. This is a basic voltage drop test across the terminals of a battery to quickly diagnose a problem the customer was having with his vehicle not starting.
