Question:
Hello I am having issues with my electric brakes on a horse trailer. I used a jumper pack to apply 12V to the trailer connector. Might have ped to 11 with the brakes now operating. What voltage should I see at the brakes? I am only seeing 8-9. What voltage does it take at the brakes for full power? Thanks

Thanks for sending the pictures. What you have there are D35 (3,500 lb) axles. The brakes you have on there now would be 10" instead of 7". To add brakes to the other axle you can use the Trailer Hub and Drum Assembly - 3,500-lb Axles - 10" Diameter - 6 on 5-1/2 - Pre-Greased # AKHD-655-35-K along with the etrailer Electric Trailer Brakes - Self-Adjusting - 10" - Left/Right Hand Assemblies - 3.5K # AKEBRK-35-SA and hardware # BRKH10B. The same # 10-1-1 from before can be used to run wire to the brakes.
