Hi I hope somebody is still following this thread I am new to this forum and have found it helpfull reading your post re the air X. Mine has been working for two years without fault, but it startred to shut down at lower volts so i attempted to adjust the shut down voltage by turning the small screw clockwise as instructed in the handbook but unfortunatly the whole unit turned, the locking nut and I suppose the unit inside must have turned. I have oiled the adjusting screw and tightened the locking nut and adjusted the screw. Now it starts fine charges for a while but then it starts nocking off and on as if there is a lose connection inside I have checked all connections to the batteries
taken the on/off switch out of the circuit and also taken the ampmeter out so ther is no fault there, has anybody any ideas to try, I have not yet had the unit in bits to look and see any advice would be very helpfull. I have considered upgrading to the new unit which is suppose to have higher output and a lot quieter.
