What Should battery voltage drop when starting?
Voltage drop on the ground side of the starter circuit should be no more than 0.2 volts. But some manufacturers will take a voltage drop reading between 0.2 and 0.6 as acceptable for the ground side of the starter circuit. If you get a higher voltage drop reading, check the starter motor’s mounting bolts for tightness.
Why does my battery voltage drop?
An excessive resistance of your high amperage circuit is an overlooked problem that can cause your volts to drop in your batteries. Check to see if the cables are corroded, damaged, or loose. Resistance is usually caused by battery terminals and cables that have not been properly cleaned.
What is the acceptable voltage drop?
5%
How much voltage drop is acceptable? A footnote (NEC 210-19 FPN No. 4) in the National Electrical Code states that a voltage drop of 5% at the furthest receptacle in a branch wiring circuit is acceptable for normal efficiency.
