Kevin Clark Posted June 21 Share Posted June 21 Trouble with Brake Buddy. I bought a used brake buddy and cannot get it to power on. I have confirmed 12v power going into the unit. Power goes into circuit board but not out of circuit board What else am I missing? Do these breakaway connections have something to do with it?

Martinvz Posted June 21 Share Posted June 21 You do not have a warranty on it anymore. So open it up and check inside. My BlueOx Patriot did the same and it has a 12v battery inside that died. Easy to find on Amazon and replaced it. Now it is still working and a much cheaper fix than $1500 for a new one. I suspect your may have a battery inside that could be replaced. 1 Link to comment Share on other sites More sharing options...
marsingbob Posted Wednesday at 05:07 PM Share Posted Wednesday at 05:07 PM There is no battery in it. It should power on and run compressor with no breakaway connection. Brake Buddy rebuilt mine for less than 1/2 new price but they will not rebuild very old units and I do not believe they will sell a control board.

Kevin Clark Posted Wednesday at 07:29 PM Author Share Posted Wednesday at 07:29 PM After speaking with Brake Buddy I believe the circuit board is bad and this one is too old to repair. I’m so disappointed! Link to comment Share on other sites More sharing options...
Kevin Clark Posted Saturday at 12:00 PM Author Share Posted Saturday at 12:00 PM I have an old Brake Buddy I am going to try and replace a relay on. If that goes well maybe I’ll try it on this board! Link to comment Share on other sites More sharing options...
