2004 - 2005 Holiday Neptune 12v interior lights fluctuate

2004-2005 Neptune Holiday 36 foot bus. It is having a problem with fluctuating lights (voltage). Also the power is going off completely for short times, when loaded down. I suspect there is an automatic 12v breaker somewhere that I can't locate. Any one with any info to the whereabouts of it is appreciated.It is not in the fuse panel and it has an inverter as opposed to a converter. Thanks

    Usually by the door you have a 12 volt disconnect switch, check it or check the solenoid it operates. Ask someone that has a motorhome like yours where these items are located.

    Incandescent or florescent or both? I don't know if any 12v circuit breakers...those are usually reserved for 120vac. The 12v system uses fuses to protect them and if one goes out....it's out. There's no in between. Sounds to me like you're having a problem with the transfer switch or converter. Are you connected to shore power? Does it do the same thing while on your generator? Have you measured your voltage?
