Check to see if you accidentally tripped the battery cutoff switch - happens to me on occasion. If that doesn't resolve it then check the battery voltage. If the battery voltage is OK then look for an auto reset circuit breaker often located near the battery (here's pic of one on amazon https://www.amazon.com/Bussmann-CBC-50HB-Circuit-Breaker-Model/dp/B00YL1HCQ4/ref=sr_1_30?s=sporting-goods&ie=UTF8&qid=1470409500&sr=1-30&keywords=auto+reset+circuit+breaker If the breaker goes toes up then it cuts off power from the battery to the rig.
