TYPICAL CHARGING SYSTEM- SUMMARY NOTES
Following are a few notes regarding the charging system
or specifi c charging system components.
1. With the battery charger unplugged from shore pow-
er the battery charger is not generating any DC power.
However, the battery charger is connected to the batteries
through the battery switches and charger breakers which
are located on the battery management panel. The char-
ger breakers would stop any short in the wires that run s
directly to the battery charger. Remember that the char-
ger is connected to the battery side of the switch and is
continuously “hot”.
2. There is a breaker protecting the battery charger cir-
cuit. A primary cause of the breaker to “trip” would be
if the positive and negative battery cables were crossed.
The above situation could easily happen if someone was
trying to start a battery with “jumper cables.” To a lesser
degree should a wire delivering current from the battery
charger chafe a fuse may “blow” and the battery charger
would cease its charging operation. See your Regal dealer
for ordering extra fuses for your charger.
2. If one of the cranking batteries is weak or “dead” fi rst
start the generator up and let it run awhile as it will send
an initial charge to the weak battery. Then engage the bat-
tery parallel switch to start the engine.
3. Always turn the universal battery switches on the bat-
tery management panel to the “off ” position when leav-
ing the vessel for extended periods. Select breakers that
control specifi c safety functions of the boat will operate
as normal even with the battery switches off as displayed
by lights engaged on the management panel.
4. When leaving the vessel after connecting your dock-
side power cord turn the battery charger breaker at the
management panel to the “on” position. This will permit
the battery charging system to energize the appropriate
batteries as needed.
5. The Bosch relay located inside the battery management
panel is connected to the remote battery switch. It closes
when the universal battery switch is activated at the bat-
tery management panel.
6. Remember the appropriate engine will not crank over
with the universal battery switch in the “off ” position.
7. An internal battery charger fuse protects the entire cir-
cuity from reverse connections. For example, if someone
was attempting to “jump” start an engine and had the
polarity reversed on the jumper cables this action may
cause the internal fuse to “blow” thus making the charger
inoperative.
Bottom line- always remove a battery if using a trick-
le charger. It is not recommended to jump start using
booster cables.
