Tips on Electrical System Use and Maintenance
Part III: DC Systems

If you have electrical
problems and your system looks something like this,
then you needn't look much farther for the source
of the problem. |
 |
Not every
electrical system is going to be this neat, but
this is the way it should be. |
 |
This illustrates why
crimp-on ring terminals, wing nuts and other substandard
high amperage cable connectors should never be used.
High resistance has melted the cable insulation
and burned up a $900 starting motor because of high
resistance. |
 |
Corrosion
takes its toll even on the interior of the boat
due to leaks, salt air and high humidity. When tested,
most of these connections had high resistance. This
is the proper method to splice wires. |
|  |
Looking at
this ball of wiring hanging down, is it any wonder
that a lot of electrical equipment on this boat
didn't work? Instrument panel of this open boat
was not kept covered. Water pouring through the
panel had even filled up the battery boxes with
water. |

Close
up of wire bundle at left. These supposedly water
proof wire connectors, on closer examination, are
found to be full of water. |
