Battery to starter lead resistance
The resistance of the lead(s) used between the battery/batteries and the starter motor must not be more than
0.0017 ohms for 12V systems and 0.0034 ohms for 24V systems. More detailed information on types of battery
is available from the Wimborne Marine Power Centre.
