STEP 4: Incorrect wiring will result in reverse polarity or high reverse voltage, in the event this
happens, the ProSport 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 caused
by putting the "red" + lead on a - negative battery terminal) and or the (high reverse DC voltage
caused by taking one bank cable and spreading it across two batteries) is corrected, using the
wiring diagrams as shown on pages 16-22. In the event of a reverse polarity connection or an
improper battery connection or if an output is not connected to a battery the appropriate red
battery bank trouble LED will illuminate identifying the battery and wiring connections where a
fault is present. See page 25 for further details.
