Dexter E/H 1600 Brake Actuator
Anybody have a similar experience or can provide me some insight/advice?
We arrived at our RV park this afternoon and set up. Almost immediately after I flipped on our 50 amp breaker, we could hear a humming noise. This sound was not apparent when we arrive and were setting up. I assumed (incorrectly) that this was our inverter/battery charger simply cranking up to charge the batteries. Well, after a few hours of constant humming, I decided to get off my @#$ and investigate. Turns out the Dexter E/H 1600 electro/hydraulic actuator was humming away. Only way I could think of to get it to stop was to remove the 12 volt power cable. I let it sit a while, then re-attached the cable. All is quiet. One other thing. I could not pull the emergency break away switch lanyard. It seemed to be frozen in the switch.
So - I was supposed to be leaving tomorrow morning. I was initially thinking I would simply hook up the truck, connect the trailer, confirm the trailer brakes were not locked when towing, and confirm the truck brake controller could activate the trailer brakes properly. BUT - Then I got to thinking, what if whatever caused the actuator to engage and stay engaged happened again while I was towing. That put a little fear in me and makes me want wait and have a mobile tech inspect everything on Monday.
Anybody have a similar experience? Any reason to think flipping the 50 amp service breaker on would trigger the break actuator or is this simply coincidence? What else could have caused the lock-up? Brakes were not hot when we arrived and all seemed fine. I'm fairly confident that the actuator was not locked prior to arrival at the RV Park.
