Do not power any depth sounders or fish finders from the trolling motor battery.
Connecting electronic equipment to the trolling motor batteries can cause
electrical interference. Any depth sounders or fish finders must be powered
from the engine starting or accessory battery.

Battery Precautions
!
WARNING
An operating or charging battery produces gas that can ignite and explode,
spraying out sulfuric acid, which can cause severe burns. Ventilate the area around
the battery and wear protective equipment when handling or servicing batteries.
When charging batteries, an explosive gas mixture forms in each cell. Part of this gas
escapes through holes in the vent plugs and may form an explosive atmosphere
around the battery if ventilation is poor. This explosive gas may remain in or around
the battery for several hours after it has been charged. Sparks or flames can ignite
this gas and cause an internal explosion, which may shatter the battery.
The following precautions should be observed to prevent an explosion:
1. Keep flames away and do not smoke near batteries being charged or which
have been charged recently.
2. Do not disconnect the battery cables while the trolling motor is operating,
because a spark usually occurs at the point where a live circuit is broken.
Always use care to prevent reverse polarization when connecting or
disconnecting cable clamps on chargers. Poor connections are a common
cause of electrical arcs, which cause explosions.
3. Do not reverse the polarity of battery terminal to cable connections.
Wire and Cable Routing
•
Route the trolling motor wires on the opposite side of the boat from other boat
wiring.
•
Sensitive electronics, such as depth finders, should be connected directly to the
main engine battery. Single battery systems require separate connection
cables.
