Is It Normal For The Breakaway Switch Of The Invisibrake To Still Work When Not Hooked Up To Tow

Question:

Hello. I purchased the Invisibrake system from etrailer a few months back and finally found someone to install it for us on our 2017 Jeep Wrangler Unlimited. After getting the Jeep home it was not connected to the motorhome at all I noticed that the break-away pin was still ed so I pulled it out and then the Invisibrake started up. The key was not in the ignition! I let it go for about a minute before reing the pin. My question is, is this typical of a proper installation? To have the unit operate even without being connected to the MH or having the key in the ignition? If so, is there some way to power down the unit? Just in case some clown walks by and decides to pull out the pin and take off? Thank You,

Yes, this is exactly how the Roadmaster InvisiBrake Supplemental Braking System # RM-8700 breakaway switch should work. You wouldn't have the key in the ignition when flat towing the vehicle either so that won't be a factor here. This system is going to have power from your Wrangler's battery and activates only when the stop lights on your motorhome are illuminated or if the breakaway switch pin is pulled.

The only way to prevent it from activating would be to cut power to the main unit to prevent the cylinder from actuating. If you pull the fuse on the power wire after you're done towing then it will cut all power to the unit and prevent it from activating in the event that some clown pulls the pin and walks off with it.
