battery shut of switch panel panel

[henry]

i have a 1987 carver 3297 mariner there is a 50 amp circuit breaker in the panel i have no 12v power and this breaker will not re set anyone know the part number and would render the 12 volt inop

If the breaker does not reset, it could indicate an overload in the 12V circuit and not necessarily a malfunctioning breaker,

I agree with uchu. Do some troubleshooting first before you go replacing it.

Does the pic below look like your panel? Is it the "Main" breaker on the left that's not resetting? (if so) Did you shut off ALL the other breakers on that panel before turning on the main? If that's the one that is tripping, then yes you wouldn't have any DC power to anything except the auto float switch for the bilge pump and maybe the voltmeter(s). Those usually go direct to the battery switch and bypass the main breaker. They are a common breaker, usually made by Carling but a replacement is probably available from Blue Seas too.

Is there any resistance when you move the toggle or is just floppy ?

no its not the main panel its a seperate panel for the battery shutoff switch the pust to set cb is in this panel the boat is in storage now i went to charge batteries and found no 12 v power to boat put charger on bit still no 12v in boat checked the panel and found 50 amp cb was popped would not reset not sure what this cb controls

Something must've overloaded the circuit and popped the breaker. Are the batteries dead?

You need to get out there and get that thing charged back up. A battery at 8 volts can FREEZE and will cause damage internally.

Good chance the battery is bad now anyway being so low, try and charge it and see but don't be too surprised if it doesn't have capacity left.

Did you ever find out what the CB was to/for ?
I'm having the same issue, except my batteries are fine.
