• Troubleshooting Reverse Lockout Solenoid Replacement on 2006 Mastercraft Trailer
  Thanks for the explanation. The Solenoid Valve Replacement Kit for Titan/UFP Brake Actuators with Reverse Lockouts # TK71-755-00 is what you can use for that style coupler. It simply has another connection for a drain to give you the bypass. Since your current one has this, you can simply remove the wiring and leave it in place with the Titan # T4748800 you have behind it. Simply connect the wires to that unit and you should be good to go. If you prefer to remove the old one you can...

• Troubleshooting UFP Surge Brake Coupler Operation
  The electric lockout doesn't do anything to the actuator itself, it is a solenoid that doesn't let the fluid pressurize to case the wheel cylinder or brake caliper to engage. The coupler not returning to the forward location has more to do with the Replacement Shock Absorber Spring Kit for Titan/UFP Brake Actuators # TK71-758-00. If you want to use the manual key, it won't be an issue.

• Troubleshooting Titian Actuator with Electric Lockout Not Working When Backing up Driveway
  If your electric lockout solenoid on your Titan actuator isn't engaging when you are backing up your driveway then either the wiring is broken so it isn't receiving the signal or the solenoid has gone bad and it needs replacing. Check the wiring and if it looks good then the solenoid itself it likely the culprit and you would need part # T4748800 for Titan Model 6, Model 60, Aero 7500, and newer Model 10 and Model 20 actuators. If you have a 2000 or older Model 10 actuator, the adapter...

• Adding Electric Lockout and 5-Way to Trailer with Titan Model 60 Actuator
  To add an electric lockout to your Titan Model 60 actuator only requires the part # T4748800 and then if you wanted to add a shroud to protect the lock out you'd also need the part # T4835800183. To activate the electric lock out you need a reverse light circuit carried to it. Typically a 5-way is needed for this to carry the extra circuit. For a 5-way you'd then want the part # W002290 which you can replace your 4-way with. For a 7-way to a 5-way adapter then you'd want the part #...

• Is an Electric Reverse Lock Out Required for Backing Up a Trailer with Surge Brakes
  There are 3 ways to allow a trailer with surge brakes to back up. There can be an electric reverse lockout, a manual lockout, or you can use free-backing brake assemblies if the brakes are drums. The easiest and most-preferred method is the electric reverse lockout like what comes on the Titan Model 6 part # T4747220. Or for just the lockout you would want the part # T4748800. I also attached a link to a page that has all of the free backing brakes we offer.

• Does Trailer Surge Brake Solenoid for Reverse Lights Draw Enough To Overdraw Reverse Light Circuit
  I understand your concern, but we've yet to see a reverse lock out solenoid overdraw a reverse light circuit and we see this type of setup pretty frequently. For example, the Titan reverse lock out solenoid part # T4748800 only draws 8 watts so it doesn't really draw much.

• Surge Brake Actuating Coupler With Reverse Lockout Boat Launching
  With your Titan surge brake actuating coupler with electric lockout # T4748800, I recommend unplugging the wiring before launch. The issue with most is how long before launch does it need to be unplugged. Obviously there is some maneuvering prior to launch that it is helpful to have brakes deactivated for so I recommend disconnecting the wiring just before you put the trailer axle into the water. This will keep all of your electrical safe from any water and electricity issues and will...

• Troubleshooting Titan Surge Disc Brake Actuator
  It could be that your reverse lockout solenoid needs replacement. Part # T4748800 is the replacement part. But I suspect your master cylinder is the cause for the brakes staying locked up until you release the pressure from the bleed valve on one of the calipers. You can check your master cylinder to see if the piston returns to its normal position after you manually compress it. If not you will want to replace it with part # T4747100 which fits the model 10 disc actuator. For the same...

• Signs that Solenoid Valve for Titan Brake Actuator with Reverse Lockout #T4748800 Needs Replacement
  I spoke with my contact over at Titan and while they couldn't provide the actual ohm reading you'd get when testing the Replacement Solenoid Valve # T4748800, he did give some information that may be helpful. You'll need another person to help you verify this first one, but when you put the vehicle in reverse you should be hearing a distinct snapping noise. If you don't hear a snap when trying to back up, the solenoid is bad and will need replacing. He also mentioned that this solenoid...

• Normally Open Reverse Lockout Solenoid for Disc Trailer Brakes
  The normally open style like # T4748800, will only prevent fluid from going back to trailer brakes when you put the vehicle in reverse. Once the vehicle is in reverse, the normally open solenoid will close and allow you to back up without the brakes engaging. On a normally open system, you will need to be careful when backing up because if you hit a curb or another object it could add even more pressure to the master cylinder and could possibly damage it. A normally closed system...

• Adding Reverse Lockout to Trailer with Titan Model 60 Actuator
  I really wish there was a cheap and easy way to lock out a Titan model 60 actuator but the only way would be with an electric lock out like the part # T4748800. This threads onto the back of your current actuator and once ran to the reverse light circuit it will allow your trailer to backup without locking up the brakes. You will need to replace your current 4-way with a 5-way like part # HM47910. And then to convert the 4-way on your tow vehicle you'd need the adapter part # 20036...

• Is the Titan Reverse Lockout Solenoid Compatible with Non-Metallic Master Cylinders?
  The Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800 is compatible with a variety of master cylinders just like the Demco Reverse Lockout # DM11993. Either will work with a plastic master cylinder like the Demco # 5650. I recommend going with the Demco Solenoid because it is made to be a non-bypass solenoid so it seems to function a little better.

• How Does a Reverse Lockout for Surge Brakes Wire to a Trailer
  The wiring of the Replacement Solenoid Valve # T4748800 is ran to the reverse light circuit of the trailer's wiring connector. Basically one wire will get run to the reverse light circuit and the other wire will get grounded on the trailer frame. Doesn't matter which wire. If your trailer only has a 4-way you will need a # 20036 to convert it to a 5-way so that you can tap into your vehicle's reverse light circuit. Check out the video I attached to the right for more info.

• Does Titan Trailer Coupler, # T4819900, Need A Solenoid Valve When Trailer Is In Reverse
  On the Titan Trailer Coupler, # T4819900, you need to add a separate solenoid to disable the brakes when traveling in reverse. You will want to use the Titan Solenoid Valve with Fittings for Reverse Lockout, # T4748800, which is a normally open valve. It is internally grounded so you just have the one wire to attach to the reverse light circuit. The difference is the normally open lets the brake fluid still circulate through the brake lines, where as the normally closed valve would...

• How to Back Up Trailer with Surge Brake Model 60 Actuator Installed
  The issue is that with the way a surge coupler works when backing up, normally up hill, the trailer is pushing the other way which will cause the actuator to compress in sending fluid back to engage the brakes. This makes it very difficult or impossible sometimes to back the trailer up. Your Titan Model 60 actuator would need to have a lockout solenoid installed on it so that it could back up. For that you'd need the Titan solenoid part # T4748800 and you'd be able to back the traler...

• Brakes Lock Up in Reverse But Will Not Work While Moving Forward with Titan Model 10 Brake Actuator
  I spoke with my contact at Dexter who owns Titan and they informed me that there could be a few different issues. If they are drum brakes and they were just installed then most likely they are installed on the wrong side of the trailer as this is the most common issue with this problem. The reverse solenoid part # T4748800 could also be installed backwards as this would then shut off the flow of fluid while going forward but not backward. If the actuator still does not work once you...

• Installation of Electric Reverse Lockout Solenoid for Surge Brakes
  If you don't install the reverse lockout solenoid # T4748800 that came with your actuator, then unless you have free backing brake assemblies, you will not be able to back up without activating the brakes immediately. This solenoid basically works like a valve not allowing the hydraulic brake fluid to move through the brake lines to activate your brake assemblies. Because you have a 4-way, I recommend you add the Hopkins Endurance 5-Way Flat Trailer Wiring Kit - Vehicle and Trailer...
