Battery terminal thing corroded/broken, what to do?

[artz]

I wasn't sure what to call this thing, so I took a picture so you knew what I'm talking about.

The terminal that connects my battery to the RV is corroded, and not letting electricity in.

I began to disassemble it by loosing the rusted nuts. One of them got stuck, and while turning it, the terminal screw began to turn too. I can not take the nut off.

I am wondering what to do - is this thing replaceable? Should I just attempt to clean it with the screws still attached?

Thanks for your advice!

They look fine to me. A bit rusty but nothing a little spray won't fix. Are you having electrical problems?

 

[artz]

Yes, I am not getting battery juice inside the trailer. This happened last year, and cleaning fixed it then when I was able to disassemble and clean the contacts.

After clean it this time I would spray it with something like battery terminal spray or something to protect it from the elements.

Try removing the connector completely from the frame to access the backside. You may be able to hold the screw from that side while you remove the nut. Rust (iron oxide) is not a good conductor of electricity. I would consider remounting those connectors inside an exterior grade junction box with rubber grommets where the wires enter/leave it. Those little red rubber boots are not meant to be weather protectors.

Can't access the back side John. Those are a couple of DC circuit breakers. On the other hand, they only cost a couple bucks to replace.

Would you happen to have a link to a viable replacement part?

I tried unscrewing it but those screws are really hard to turn and get a good grip on with the screwdriver.

You should be able to get replacement breakers at any automotive supply house such as NAPA.

It looks like the mounting screws are self taping and don't have a nut on the back side. It also looks like this some kind of fuse link, if this is I would go to auto parts store and get a weather prof in-line fuse they come in all sizes.

Thanks, found this: http://www.napaonline.com/Catalog/CatalogItemDetail.aspx?R=BK_7823003_0361081943

Or maybe something like this would be more weather resistant? http://www.napaonline.com/Catalog/CatalogItemDetail.aspx?R=BK_7823157_0006522027

What's the right Amp rating?

What's the right Amp rating?

The amp rating should be stamped into the breaker. Look closely.
It could be 20, 30 or 50.

Go back to NAPA site type in fuse holder one maybe one to look at is part no. BK7304350.

Think I found the exact one: http://www.wiringproducts.com/contents/en-us/p1153_12_volt_circuit_breaker.html

I managed to finally get it off by sawing it.



I will take it to the NAPA near me and see what they can do, hopefully I will be back in action then.

My hands hurt, time for a beer.
