Product Information

We invented the Star-Tron, which was the first trailer and accessory isolator, in 1988.
.We invented and introduced the first isolators to the market in 1988 when others argued we were wrong and trailer circuits didn't need isolation. Now these same people are building cheap copies and preaching that isolation is needed. Our Trailer and Accessory Isolator protects your motorcycle wiring by keeping the electrical load off the original wires. Increases the life of the wiring by reducing the heat caused by current flow in the wiring. If your motorcycle has a computer controlling operations or circuits are electronically monitored then this unit is even more important because it keeps the additional load of the trailer off the computer. Our newer solid state model was substantially reduced in size from the Star-Tron 3½" x 5" to a compact 1½" x 3" so it would fit in the smaller spaces and even under the seat on some of the newer motorcycles. Since most people use it solely for a trailer the new model is designed primarily for that purpose. If accessory isolation is needed it requires a separate unit.

It works on any 12 volt standard negative ground system, even on automobiles.
Isolates the circuits by powering the turn signals, brakes and taillights through the unit and avoiding any power carrying connections to the motorcycle wiring.
Hides the load from computer or circuit monitoring devices.
Control of each circuit is through the isolator.
It's smaller than our earlier Star-Tron units so it fits on many more motorcycles and increases the number of places it can be mounted.
The latest in miniaturization offers a small, totally solid state, rugged unit. Ours is the only unit on the market that doesn't use any relays which wear out after time.

This unit creates a secondary electrical supply circuit that does not pull power from the original wiring. Thus, it does not plug into the original wiring. The control circuits for the trailer lights are simply tapped into the brake and turn signal circuits on the motorcycle. The output wires connect directly to the trailer (plug) lights. It's highly recommended that the circuits be fused. Without fuse protection a short in the trailer wiring or lights will destroy the unit.

Important information about your trailer hook up. You can connect the trailer circuits to your motorcycle and in some cases problems are immediately encountered. In other cases, like on the Harley-Davidson, your trailer and signals initially seem to work properly. However, after a period of time you encounter some problems with the signals for a period of time after the trailer is disconnected. It's common for electronics like computer modules to start giving you warnings something is wrong. You have two choices of fixing it immediately before more damage is done or ignore it and pay to replace the module after it fails.

We've evolved our isolator into a modern compact "dual circuit board solid state device".

This unit is for the "discerning rider" who wants the ultimate in electrical protection for his motorcycle and purchases only the best. The kind of person that says "I don't want cheap". He's worked hard to reach a place in life that's taught him that the best more times than not saves money.

Copies on the market are some wire, a couple of plugs and $3.00 worth of old fashioned relays.
Not even as sophisticated as our 1988 Star-Tron and certainly not on the same stage as our new Trailer Isolator.

Information about trailer plugs and wiring harnesses. Most new trailers come with the mating plugs, one for the trailer and one for the motorcycle. There are numerous types of plugs on the market as shown below. So you don't have to rewire your trailer to accommodate our preference we utilize the stock plug arrangement provided by your trailer manufacturer. The trailers are normally pre wired and the mating plug is ready for connection to the proper circuits on the motorcycle or isolator. This method keeps your brand of trailer consistent with their other models. Some people like to install a fancy plug that's in a chrome housing in which case you will need to change the plug on the trailer. Using these stock plugs the only thing you'll need is our Trailer Isolator and nothing else.
