Check to see if you have 12 V going to your converter. If you can't get to the main terminals pull a fuse and check both sides of where they plug-in.
If you don't have 12 V there pull the thermals off the battery and clean them real good. When you checked the battery make sure you check it on the clamps, not the terminals of the battery itself. Check the converter for power again. No power? Try to trace the wires as best you can towards the converter from the battery. Look for any type of circuit breaker or fuse that is in line. It will be on the red line, the positive side. If you restore power to the converter and you still don't have anything working you got a bad converter. I hope that's not the case.
