check with your multi meter the resistance of the primary and secondary coils on the wee transformers mounted on the invertor they often go open on the secondary, secondly check the fuses of course on the inv. and finally the output ceramic caps between the invert outputs and earth they also often go... hopefully you'll find something that'll be an easy fix good luck !
