Should There Be Continuity Between Ground and Brake Output Pin On 7-way Connector?
Question:
Should I be seeing a closed connection when Ohm’ing between 5-7 or ground and trailer brakes on 7-way connector? I’m having issues with brake system on truck and wanted to make sure this is t the culprit Thanks

Expert Reply:
You should have continuity between the 5 o'clock brake output pin and 7 o'clock ground pin in your 7-way connector with the brakes applied.
I recommend turning the trailer brake controller to its max setting and having someone apply the manual override while you check for continuity. If you do not have continuity then there is either an internal issue with the controller, or one of the grounds has gone bad.
Let me know what you find and I would be happy to go through some troubleshooting steps.
I included a link to helpful article on wiring for you to take a look at.
