Mine has a circuit breaker with 2 posts on it It's just standard size. There is a very small button that is hard to see, but you can run your finger around the breaker When you find the little button push it in and it should reset the breaker. I had this happen the end of June and a very wise service man in Amarillo talked me through everything. That got my 12 volt power back. That simple. May not be your problem, but give it a try. This breaker should be close to battery box and will be mounted one of the storage bins. Mine was on back wall of the very front compartment. Hope something works.
