The heater option cannot be used with the 33AH battery application.
1.
Locate the J15 plug on the control board and disconnect it.
2.
Connect the white jumper from the 33AH wire harness kit between the
positive (+) terminal of one battery and the negative (-) terminal of the
other battery.
3.
Connect one end of the red (+) wire from the 33AH wire harness kit to
the red wire from the J15 plug as shown. Connect the other end of
the red (+) wire to the positive (+) terminal on the battery as shown.
4.
Connect one end of the black (-) wire from the 33AH wire harness kit
to the black wire from the J15 plug as shown. Connect the other end
of the black (-) wire to the negative (-) terminal on the battery as
shown.
5. Turn ON AC power to the operator.
6. Turn ON the AC power switch on the operator.
7.
Reconnect the J15 plug to the control board.
