This application shows how a 'Genie' can be used to charge a 3 battery bank system, for a 2 battery bank system connect the Yellow & Green battery sense leads together and use a XSP**/1/2BS or an XP**/1/2, for a single battery system connect all 3 battery sense leads together and omit the X-SPLIT Each battery bank is electrically isolated from each other but is charged simultaneously where each battery bank will draw the amount of charge from the charging source according to the charge state of each battery bank. Auxiliary charging sources such as wind generators, solar cells can be paralleled to the alternator input but must be switched of prior to switching on the ignition to allow the'Genie' to measure the true battery voltage. The fuse fitted in series with the sense feed is recommended especially if either service battery is heavily depleted, if the auxiliary batteries are heavily depleted at the time the ignition is first switched on a heavy charge current may be drawn through this circuit. The optional bulb is used under these instances to limit the maximum current draw via this circuit. If the optional bulb is too small' oscillation of the 'Genie' indicating lights may occur and the control unit may not initialise correctly. It is not advisable to use battery select switches or other mechanical forms of battery selection techniques in conjunction with the 'Genie' unless all the sense leads are taken to the common input terminal as the control unit must always see the output of the alternator. Tacho output is via a 'stator tap' on the alternator. As the standard Genie alternator does not have a separate excitation winding there is no direct charge warning light output, i these circumstances it is possible to use the optional bulb as a charge warning light providing the requirements are met.
