Blm box

[Jann]

How do you open the BLM Box under the hood on a 2017 Thor Ace 30.1?

[16ACE27]

What is/are you calling a "BLM box"?

[Jann]

I think it is the fuse box under the hood. I have problems with power to my dash - radio, DC connections, computer outlets and I read to check the BLM under the hood for fuses. Also, I checked under the driver's side but I can't open the fuse box because the radio speaker prevents the door from opening. One thing after another...

Thanks for any help you can give me because I am definitely a novice when it comes to things like this.

My question is:
What will you do in there once you get the lid off?

100 well placed dollars at any stereo install store will likely cure all of your problems.

Jann you posted previously asking about the PDB (Power Distribution Box) under the hood I think....how to open to check for a blown fuse on your dash cigar lighter outlets. Maybe your PDB is different than mine, but there is one plastic latch at the bottom right side you have to lift up to release and then just swing open the PDB door exposes the fuses. The cigar outlets are fuse 22 (20amp). Reattached my picture from a previous post.

I can’t find any latch on the bottom right corner and my box looks like yours. I tried attaching a picture but it’s asking for a URL where my picture is and it’s on my iPhone. You’re probably right about going to a stereo install store!

No problem Jann. Sometimes working on RV systems is very awkward and not easy to find and access devices for any of us. If your Power Dist Box has arrows on it like those shown in my picture.....it should point to where the release latch is.



It might be safer for you to call a mobile RV Tech service and have someone come to your location and help you out. It is worth the cost to resolve your issues and do no more damage to you or the coach. Sit back, make a call and have a coffee.

Thank you I finally got it open!!!! Now to find the fuse. The Thor manual refers to a BCC Fuse Panel but this Power Dist Box doesn't look anything like it. Also, they refer to one under the driver's side but I can't access that because the speaker is over the box - unless I remove the speaker. Lordy Lordy...why me???

The fuse box you have opened is for Ford OEM fuses; it is not the BCC box and I doubt you have a BCC - you probably have a BIM.

On my 2016 ACE all my speakers are in the ceiling. Did you buy this coach new or used? Could the previous owner have installed this speaker over the Thos installed fuse panel near your driver's left foot? Take a picture of it.

What are you trying to fix anyway?

You're right...have no idea what to do once I got the box open because it doesn't look like any fuse box in the Thor manual. LOL

I bought this Thor Ace 30.1 new. The Axera radio with my backup cameras has no power. Also, the DC connections have no power on the dash. This ACE has a computer setup on the passenger side and the DC and AC outlets have no power. I researched everything I could because we are up in the mountains in NC and not near any kind of service Techs. Came down to it may be a fuse...at this point God knows.

To post a picture I don't use the "insert image" button. I use the paperclip icon and it allows you to find your file and then make sure to hit the "upload button". As mentioned before, my 20 amp cig lighter fuse was blown and found in that box. You probably know, but you're 110V outlet won't work unless you are on shore power or running the generator. There are also a couple of reset-able breakers that you can also check but I can't tell you where they are on your coach. Usually one near or even behind the coach battery.

When I select Reply it doesn't show the paper clip icon...that's what I have always used to attach pictures. It only has the "Insert Image" icon, which after google showed me how to get the URL I tried. Picture ended up in the middle of my reply....

[reminckv]

I'm fairly new, but the only thing I would suggest is to make sure you are signed in and see if the paperclip icon shows up. When I follow the link from an email, it doesn't show up for me either.

I'm not much help on electrical troubleshooting, but trying to keep the thread going for you and maybe someone will chime in. Does all of the other 12V devices in the coach work other than the dash outlets? If so, you are probably on the right track looking at fuses either in the engine bay or under the dash.

Click the "Go Advanced" button to see all the available icons. Your picture is too small to be useful, it's only a thumbnail.

The radio/cameras/12 VDC power outlet at the desk are all house DC loads. They will not be powered from the Ford fuse box, they're probably fused from the Thor box by your speaker.

On our 17 ACE 30.4, the speaker makes it difficult to open the panel door, some bending and pushing is required. Now that I have it open, it will stay that way. Not sure about your ACE but on ours, there is another fuse panel above the one by the speaker. It has several fuses that control the accessories.

Finally got the fuse box open by removing the speaker!! No fuse for radio. After a week of searching and removing and doing everything under the sun...there is a pin hole button by the AUX plug on the Axera radio, which is a RESET button!!! Weeks of frustration. It now works!

BUT I still don't know where the radio and camera fuses are in this RV! 2 Fuse boxes by driver's side and fuse box under bed but nothing indicates radio??? Another day I guess.

A common problem with an easy fix that dozens of people have found the answer to on this forum by stating the problem (I can't turn my radio on) and asking for help.

You made it more difficult by asking about a "BLM" box and stating in post # 11 that "radio with my backup cameras has no power. Also, the DC connections have no power on the dash. This ACE has a computer setup on the passenger side and the DC and AC outlets have no power. " so we assumed you had actually put a meter to these things and determined you had no power. Accurate descriptions of the trouble symptoms get more helpful responses.

So now you got the radio working, what about the other outlets?
