Elmer,
This is an alternative wiring diagram. It will allow the bow thruster to
start the generator without discharging to the other batteries.
I moved wire 5pa, and added two 150 amp fuses
We need to talk.

Main Engine Start/Run
Sequence
• Set Sw#1 to the “Batt. #2” position.(House Battery)
• Set Sw#2 to “Batt. #2” (power for main engine/generator
starter, do not switch
“off” while main engine or generator are running.)
• Set Sw#3 to “On” (Bow thruster/ aux. power connect.)
T/S Patricia Divine
Under way Sailing
Main Engine Stop* Sequence
with A.C. Generator off
• Set Sw#1 to the “Batt. #2” position.(House Battery)
• Set Sw#2 to “Batt. #2” (Power for engine/generator
starter and generator run solenoid)
• Set Sw#3 to “Off” (Bow thruster aux. power connect.)
This will prevent the discharge of the bow thruster battery to house loads.
*make any/all switch changes after main engine has stopped.
Patricia Divine
Main Engine Off*
with A.C. Generator On
Heart Interface circuit breaker On
(as battery charger)
• Set Sw#1 to the “Batt. #2*” position.
* After generator is started, the charging of both “House” and “Engine
Start” battery banks is by the Heart interface battery charger.
Make sure the Heart Interface A.C. circuit breaker is “On”, and the
Interface controls are “On”
• Set Sw#2 to “Batt. #2” (Power for engine/generator start
and generator run solenoid)
• Set Sw#3 to “On” (Bow thruster aux. power connect. To
charge bow thruster battery).
*make all switch changes after main engine has stopped
Dockside, Main Engine Off
with A.C. Generator Off
Heart Interface On (as battery charger)
• Set Sw#1 to the “Batt. #2” position.
To charge both House and Engine Start batteries, using the Heart
Interface as a battery charger:
Make sure the A.C. circuit breaker marked “Battery Charger” is “on”,
and the Interface controls are “On”
• Set Sw#2 to “Batt. #2” (Power for engine/generator start
and generator run solenoid)
• Set Sw#3 to “On” (Bow thruster aux. power connect. To
charge bow thruster battery).
Patricia Divine
Main Engine Start/Run Sequence With
“LOW” Engine Start Battery
• Set Sw#1 to the “Batt. #2” position.
• Set Sw#2 to “Batt. #1”. This will give you
power from “House Battery” to start Main
engine/generator..... ( Never switch to “off” while main
engine /generator are running).
• Remember to switch off as much of the “House “ power
demand as possible!
• Set Sw#3 to “Off” (Bow thruster aux. power connect. )
When all has failed!
Main Engine/Generator Start/Run
With “LOW”:
“Engine Start Battery” and
“ House Battery”.
• Set Sw#1 to the “Batt.#1” position.
• Set Sw#2 to “Batt. #2” position
Remember to switch “off” as much of the “House “
power demand as possible!
• Set Sw#3 to “ON” this will back-feed power to start
generator first.
• Start Generator (Use Decompression to aid start)

When all has failed!
Main Engine/Generator Start/Run
•After generator start, turn on
heart interface battery charger
to charge main engine battery,
and house battery. Charge for 15 min.
•Switch SW#1 to “Batt. #2”
•Switch SW#2 to “Batt# 2”
•Switch SW#3 to “On”
•Start Main engine.
go to next page
When all has failed!
Main Engine/Generator Start/Run
After main engine is running:
Check if the alternator is charging by switching off
battery charger circuit breaker and checking
alternator output ammeter and system volt meter on main
DC electrical panel.
If charging is indicated by a current above 10 amps and
voltage above 13 volts, you may stop the generator.
