Advanced Marine Electrics and Electronics Troubleshooting A Manual for Boatowners and Marine Technicians

24 electrical systems troubleshooting

First, you enter some basic information, such as whether

the battery is in or out of the “vehicle.”

Then you enter the type of battery connection: top post, side

post, or “remote.” This last option accommodates testing

from the “jump start” terminals now incorporated on some

over-the-road vehicles, and even some new boats. You can

use this option to hook into the positive and negative DC

bus bars found behind most boat electrical panels, eliminat-

ing the need to crawl into some tight battery installation. Bat-

teries connected in series or in parallel should be tested in

isolation from one another, however, so unless it’s possible

to isolate the batteries by switching, the remote connection

option may not be practical. The unit’s red lead goes to the

battery positive terminal; the black lead to the negative.

Next, you enter the battery type: regular flooded, AGM,

AGM spiral wound (such as the Optima brand), or gel-cell.

Then you enter the battery capacity rating standard shown

on the battery label. Eight choices are provided (four are

shown), covering all world standards for battery ratings.
