Does anyone have a wiring diagram for the BD Exhaust brake with the old relay based controller? It used to be on the BD website, but they've taken it down and only have the new electronic controller.

 

I may be able to help you, is your BD Brake one of our older electric brakes or a new electric over vacuum/air brake?

What is the vehicle application?

 

Thanks in advance Dave

It is on a '95 F350. The brake is vacuum operated with one relay under the dash for the IVS and a second relay co-located with the solenoid valve in the engine compartment to cancel cruise.

I think it's tied into the EPV control somehow so that it will also operate like the old valve... and that part appears to be where my problem is.

 

Hey Joe, I am going to bring my senior tech in on this one, he feels you may have to upgrade to a DFIV (Idle Verify) system. You can contact him toll free at 800-887-5030 ext 107 Chris
or

Smart man!

 

Hey Joe, you still here,

I have some options for you but also have some questions, are you able to call me 800-887-5030.

Yeah, I'm still out here...

I have an intermitent fault, and I would like to be able to debug the currrent system. It did work before, so I'm hesitant to go $$$ buy a system when it was working before.

 

I can appreciate you not wanting to spend more money and I am by no means just trying to sell you something here, that not how I operate,my goal is to get you fixed.

The DFIV is the controller we use in our new brakes and would be an upgrade for you but like you said, it may not be necessary. I am not one of the tech here so do not want to get into all the wiring with you over the forum, probably steer you wrong anyway LOL

If you like, call here toll free and ask for Pat, he is the tech on shift today and is here until 5PM pacific time. He is good with these brakes and could probably assist you. I will brief him in preparation for your call if you so choose to call, tell him you are from FTE site.
