If you have just fitted a battery isolator and not a FIA cutout switch then it will run on the power from the altanator.

would agree with the above alternator is charging the circuit best get an autolec and wire in properly

1 of 2 ways to rectify this, either a do as mentioned before and replace the cut off switch for a pukka FIA item and wire up accordingly OR Disconnect themain charging wires off the rear of the alternator and the run 2 Heavy Duty wires direct from the alternator to the battery side of the Cut Off Switch you all ready have and then extend the wires you disconnected off the alternator to the other side of the cut off switch !!!!!

Thus by doing this the minute you turn the isolater key off not only do isolate the battery you also isolate the alternator as well !!!!!!!!
