Wiring your ProSportHD Charger Correctly
Simply choose the illustration that has the same number of charger output bank cables as
your ProSportHD Battery Charger and wire exactly as shown (choose the illustration that
matches your application) for proper charger operation.
Incorrect wiring can result in reverse polarity, caused by putting the "red" + lead on a negative
battery terminal and the "black" - lead on the positive terminal. In the event this happens,
the ProSportHD Charger has been designed to not fail as a result; however, it will cause the
charger to "internally disconnect" and provide "no output" until the reverse polarity is corrected.
In the event of miswired battery(s), the charger will illuminate a red battery trouble status LED
for the specific battery requiring attention.
When connecting each jacketed battery charger cable, make sure it is connected
to only
one 12 VDC battery
and observe the polarity and color of all connections:
Red Wire = + (Positive) Battery connection
Black Wire = - (Negative) Battery connection
The black wire can never be connected to a terminal with red wires. Only black.
Important: The pair of red and black wires in 1 cable jacket MUST GO TO THE SAME 12VDC battery.
Each charger cable
must
be connected to 1 battery,
just as shown. Observe
black to (-) and red to (+).
Do this for each battery.

Installation
When connecting to an engine start battery only connect the battery bank cable that is LABELED:
"FOR ENGINE START BATTERY USE THIS BANK CABLE ONLY".
If your application is for 4D or 8D large capacity batteries, please refer to ProMariner's website
www.promariner.com and view our ProNauticP Hardwired Charger Assortment for a model that is
correct for this group size of batteries.
Application Tip
Note: ProSportHD Waterproof Marine Battery Chargers are designed for any combination of group 24,
27, 29, 30 and 31 batteries. Each battery charger DC output cable must be connected to one (1) 12
Volt DC battery (even if batteries are configured for 24 Volt DC or 36 Volt DC trolling motor or system
applications). Most specifically you do not have to remove series or parallel jumper cables to use your
ProSportHD Charger. See typical wiring diagrams for these systems in the installation section of this manual.
Note: The ProSportHD must be connected to batteries to operate. It will not operate as a 12
volt power supply.
If there are more charger outputs than batteries, then sets of leads can be doubled on
the larger battery in your system. Typically these are connected to the more drained
trolling motor battery. Please contact ProMariner if you require assistance.
