Timothy shows the battery protection 12vdc circuit breaker, but most RVs have a POWER CENTER, TOO. Normally, a larger brown metal rectangular panel with 1/4-turn latch released by coin/finger, bottom-hinged cover. Once, opened, you find the coach circuit 12vdc FUSES AND 120vac circuit breakers.
Often at one of the following locations? Under sink, knee area, bath, master bed base or dinette base? Good Luck.
