5.4.2 Check List
The following list may aid you in finding some of the
causes of underwater corrosion. Check these wiring
connections for cleanliness, integrity, and tight contact.
1. Wiring at 12 volt D.C. panel
2. Wiring on terminal strips at or near 12 volt D.C.
panel
3. All bonding connections
14. Wiring on engine panel
5. Wiring on engine
6. Wiring on batteries and battery switch.
7. Wiring on mast step terminal strip.
8. Wiring on all optional equipment such as lorans,
VHF radiophones1 electric bilge pumps, etc.
9. Wiring on all non-factory equipment
10. Wiring on any malfunctioning equipment

CHECKING BONDING AND LIGHTNING PROTECTION SYSTEMS
Check the entire bonding and lightning protection systems
for proper operation. The bonding and lightning protec-
tion systems may be checked by using a ohmmeter to show
that continuity exists between each piece of hardware and
ground. The ohmmeter must read ~ resistance for each
piece of hardware. If 11011 is not indicated for each check,
the wiring and connections at both ends must be inspected,
cleaned, and/or replaced.
NOTES:
1. All power must be disconnected before using an
ohmmeter.
2. If a switch does not shut off (open) properly, it
is a source of stray current.
3. Reverse wiring is a source of stray current.
5.5.1 Propeller and Shaft
Propellers and shafts are large pieces of hardware with
good conductivity. Therefore , they are an ideal path for
stray currents to leave the boat. Thus , propeller and
shaft corrosion are two of the most common results of stray
current.
The propeller shaft and propeller are connected to the
bonding system via a bonding strap which bridges the shaft
coupling.
5.5.2 Electrical Switches
Electrical switches and hardware are another major cause of
stray current. The following switches and hardware should
be checked for proper operating condition.
1. All 12 volt D.C. switches and circuit breakers
2. Battery switches
