Note: Where starting at temperatures below freezing is an important requirement, a 24 volt system is the preferred
choice

* The length of all cables in the starter circuit (whether positive or negative), should be added together to give the ‘Total
Length’
(b) Grounding the battery negative
It is recommended that the battery negative busbar is grounded as close as possible to the battery, by a substantial
connection to the bonding system in the boat. This will reduce the likelihood of interference between items of electrical and
electronic equipment tted to the boat.
(c) Battery isolator switches
A switch should be tted in the positive lead to the starter, as close to the battery as is convenient. The switch should be
suitable for a momentary current of at least 1000 Amps.
