Features:

  • Lets you easily disconnect your battery so that your vehicle can be towed behind your RV
    • Can only be used on vehicle on which battery must be disconnected for towing
    • Includes switch for installing in the towed vehicle
    • Consult your owner's manual

Notes:

  • Disconnecting the battery, whether manually or with the Roadmaster automatic disconnect, will affect your vehicle's electronics. You will need to reset various electrical components in your vehicle following use of this product.

  • A charge line, (RM-156-25 - sold separately), is a good idea if you have a braking system that is using power from the towed vehicles battery while it is disconnected.

Video Transcript for Roadmaster Tow Bar Wiring RM-766 Review

Speaker 1: Today we're gonna take a look at the Roadmaster automatic battery disconnect with the switch for towed vehicle with supplemental braking system. Now this part will let you easily disconnect your battery so that your vehicle can be towed behind your RV. Now this can only be used on a vehicle on which the battery must be disconnected for towing and it does include the switch here for installing in your towed vehicle. They do recommend to consult your owner's manual. This does eliminate the inconvenience and the potential danger of pulling your battery cable. Does include this corrosion resistant marine grade solanoid with a 200 amp constant duty and 600 amp surge.

It does work with almost any 12 volt battery. As you can see they have it all preassembled for easy installation.Now they do recommend a charge line if you have a braking system that's using power from the towed vehicle battery while it's disconnected. We do sell that charge line separately. It's part #RM-156-25 and that part will maintain the battery charge in your towed vehicle while the car is being towed. This part will include everything laid out here on the table.

It includes the solanoid with all the wiring you can see attached to it, two of the 24in long wire looms, the switch, a mini fuse, all the mounting hardware you need to install it, some cable ties and shrink wrap, and a nice set of detailed instructions on how everything operates and how it installs.But that should do it for the review on the Roadmaster automatic battery disconnect with the switch for towed vehicle with supplemental braking system.

Ordered on Saturday and received on the following Tuesday. Packaging and labeling was in great shape. Just waiting for my vehicle to arrive so I can install the equipment. I will order from etrailer again. 448963

Once I located the correct etrailer video for my vehicle, the installment was simple and works great. 577103

Great product. With the help of the excellent installation videos I was able to install this product easily. Works great. 462363

by:

The instructions were good and they were detailed. The product works as advertised. The button is made so it would be difficult for it to be pushed accidently in most places where it might be installed. The greatest difficulty for me was getting nuts on the mounting bolts for the solenoid. Also, my 2014 Jeep Wrangler had three wires attached to the positive battery post so it was not that straight forward attaching all three to the battery cable. A larger diameter piece of shrink wrap would have helped in this case. 520181

Installed in 2016 Ford Edge Titanium. Had to buy additional cable connectors that were not included in the kit and instructions did not specify they were required. I would have given 5 stars if it was at least mentioned in the instructions. 364393

Purchased the RM-766 battery disconnect for my 2017 Chevy Suburban. The installation video was a huge help. The kit has changed slightly from what is shown in the video, but it was easy to figure out. The whole installation took about 1.5 hours. Works like a charm. etrailer makes it easy to get what you need and they get it to you quick. Great Experience all the way around. 446770

The RM-766 is a solid piece of hardware and comes with absolutely everything required for the install, right down to the "Tow" and "Drive" stickers for the switch. I use it to disconnect the battery in my 2016 Ford Edge 3.5L AWD, to help make it flat towable behind my RV. It works great and I do not have to open the hood and mess with battery cables while travelling. I like it. 403629

There have been absolutely zero problems with this switch so far. Works like a charm.

I have ordered many products from etrailer and their customer service is 12 on a scale of 1 to 10. I ordered my products on the weekend and they were delivered on a Wed. I also later found cheaper prices on a few of the items and submitted the info for the 110% lower price guarantee and received the refund within a few hours. These folks are just plain great! 450642

by:

As always, etrailer can be depended upon to process, and ship the order right away. I need to disconnect the battery from my Chevy Colorado to flat tow it. The Road Master RM-766 seemed like the most convenient way to disconnect the battery. The unit is easy to install. The instructions are very generic, however in my case there was a video specific to this vehicle that provided a great resource for mounting and hookup. The only thing I am concerned about is the disconnect switch itself - I think it should be more of a "deeper" switch where more movement is required to make contact - a little concerned that it could be inadvertently activated. 504566

I received the Roadmaster remote battery disconnect in a timely manner and had it installed in my 2016 Chevy Colorado by a local RV dealer. I used it for the first time this week and it worked like a charm. I didn't lose any of my preset radio stations or any other data that I know of. Pushing a button on the dash is a lot easier than disconnecting and reconnecting battery cables. 292815

I have a 2014 Silverado that I wanted to tow with my RV. In order to tow GM calls for the battery to be disconnected. This was the only product that I fond that would do what I wanted. It is slightly over priced in my opinion but it does the job. I have attached it to my aftermarket air box and ran the switch under the hood release. This way I can use the remote to unlock the doors when I am ready to unhook. 318014

The battery disconnect installation instructions were clear and the installation went well in my 2018 Chevrolet Colorado ... in spite of the kit missing a few pieces like a second star washer for connecting the two battery cables and the second piece of protective tubing. I covered the exposed energized solenoid terminals with electrical tape to prevent an potential inadvertent short in the future when working under the hood. Works as designed so far. 664912

  • Does Blue Ox Patriot Braking System Drain Vehicle Battery
  • The Blue Ox Patriot part # BRK2016 will be powered by the vehicle battery it is installed in so over time if the vehicle wasn't started periodically the battery would run down. To prevent battery draining on a towed vehicle we typically recommend the battery disconnect part # RM-766. This will disconnect the towed vehicle's battery while being flat towed and will charge the battery as well. This taps into the running light circuit (brown wire) of the 4-way you have on your vehicle...

First, I would recommend the Hopkins wiring harness # HM56200 because we've had better luck with them not having issues after installation.

This set actually has removable arms so that when you take them out the base plates are essentially invisible. I have linked the installation instructions for you to view. For a compatible tow bar I recommend the Blackhawk 2 # RM-422. This is an all-terrain tow bar which means you will not have to be lined up perfectly straight and level to hook...

To flat tow any vehicle you will need a base plate kit, tow bar, safety cables, vehicle tow bar wiring, a supplemental braking system, and possibly a high-low adapter.

I've linked a video of when we installed it into a 2015 Focus for you.

To flat tow this vehicle, I recommend upgrading your 5,000 lb hitch to the Curt Class V Universal Weld-on Receiver Hitch # 15903 which is a universal fit for frames between 18 and 61 inches wide.

For a base plate kit you'll then need the Roadmaster kit part # RM-523182-4 which is a confirmed fit and would work well. In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle. The most popular compatible...

  • Removing Fuses to Flat Tow a 2017 GMC Acadia Limited
  • When a vehicle's owner's manual says to remove fuses I definitely recommend abiding by it. GM requires the fuses be removed in order to disable specific functions that will operate while the Acadia is set up to be flat towed. We do offer products to make the process easier whenever you're setting it up to be towed. The recommended FuseMaster bypass switches for your Acadia are # RM-76517 and # RM76514. Also, for disconnecting the battery with a switch use # RM-766.

  • I spoke with my contact at Roadmaster who said that the Automatic Battery Disconnect # RM-766 has to be installed on the positive battery terminal. The reason given in the owner's manual for your 2017 Ford Edge is that "You need the door key to lock and unlock doors when the battery cable is disconnected" (see page 238). Whether you disconnect the positive or negative battery cable the result will be the same; you will have to use a key because the key FOB won't work with the battery...

However, if you want to use the separate turn signals on your 2008 Jeep Liberty, then I recommend installing the Roadmaster 6-Diode Universal Wiring Kit # 154-792-118158 to connect the Jeep's lighting system to your RV's. To let the Jeep's system operate the brake lights, the red wire coming from the converter on this wiring kit...

  • The battery does have to be disconnected to flat tow your 2017 Ford Edge with push-button start. The automatic battery disconnect, # RM-766, is recommended to do this automatically so you won't have to spend time doing it manually. This disconnect has been used on the positive terminal with other vehicles and I see no reason why you couldn't do the same on your Edge. If you need all of the other parts to flat tow your Edge then I recommend the following parts: Base plates: # RM-524454-5...

  • The reason that the StowMaster # RM-501 is not compatible with EZ5 base plate kits like part # RM-524438-5 for your 2018 Ford Fiesta is because the quick-disconnect is permanently attached to the tow bar. I spoke with my contact at Roadmaster who said that the only tow bars that are compatible with the EZ5 kits are the ones that mount inside the hitch receiver like the Falcon 2 # RM-520.
