yes, the connection can be reverse, and also the blades of the aux fan i put, should be observe properly because of its inclination or angle placement, you have to try reversing the blades to compare the output air, mine need to reverse the blade to get the maximum air.

the FAN has 80 watts rating, so approx. 6 or 7 amps requirement, if im not wrong, hilander (my unit) has 40 or 50 amps alternator, so I think it can compensate the 7 amps. I plan to make it 2 to cover the whole condenser since currently it only cover the half, so 14 amps for the aux fan, turn it ON when needed, like traffic under the heat of the sun. turn it OFF at night.

btw, got the FAN at 650 Pesos.
