trace back from the battery and check for a fuse this could be blown. Battery could be dead or a different blown fuse on main circuit breaker. Have you completely disconnected and reconnected battery recently? if so could it be hooked up backwards? if hooked up backwards there are typically 2 blown fuses on circuit breaker and one in radio that will blow. Do you have shore power?
