TYPICAL CHARGING SYSTEM- SUMMARY NOTES

Following is a summary regarding the vessel charging sys-

tem 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 batter-

ies through the battery switches. The 105 amp resettable

breakers protect each battery circuit.

Remember that the charger 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 jump 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 Re-

gal 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 DC

battery switch panel to the “off ” position when leaving

the vessel for extended periods. Select breakers that con-

trol speciﬁ c safety functions of the boat will operate as

normal.

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.

6. 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 from the vessel if

using a trickle charger. It is not recommended to jump

start using booster cables.
