Trailer repair questions

[white cloud]

First, thanks for reading this.

I have a Big Tex 10ET. I notice black streaks radiating out from the wheel hubs. The streaks appear to be grease mixed with dirt. I am concerned that I have damaged some sort of seal when greasing the axles. Any ideas about how to repair this would be appreciated.

Also when the trailer is connected to the truck I get alerts that the trailer is not connected to the truck but the brake controller is plugged into the truck. Could this be the connector?

Is there a way to charge the brake controller battery as this trailer gets parked for long periods of time.

Thanks again for reading this.

I get the black grease streaks on the wheels of my Bri Mar 10K dump trailer when I over grease the bearings. Unless I damaged a seal, the problem corrects itself over time. I fixed the problem by installing bearing buddies so I can tell if they need grease and how much to add.

I solved the dead trailer battery problem by switching to cordless tool batteries. I just take one off the charger in the garage and plug it into the trailer each time I use it.
