All New 3 Circuit Solution (3CS-S) Sealed Kits and Components

 

We have reworked all the 3 Circuit Solution Sealed models with all new modular fuseholders that hold extra fuses, and a neater, more compact design. At the same time we’ve increased battery lead length to easier fit all bike models. The 3CS Kits on this page are generically designed for all bikes, however, please note that we have bike specific kits for some popular bikes, see here.

Introduction to our 3CS Sealed Kits:

This Kit uses Sumitomo MT sealed .090” connectors that are easy to work with if crimping or soldering. See here for a crimper for these that will do a professional job on these. The Hozan P-706 is my recommended crimper for sealed types. There are 3 basic versions of the 3CS Sealed available, depending on your switching requirements. Please read the information here carefully to decide which Kit is right for your needs.

Unswitched circuits - is necessary for battery charging and you can charge your battery with this Kit. You cannot jump start your bike with it, please do not try that. Unswitched circuits are always on even when the bike is off. Unswitched circuits are also great for GPS, allowing usage even after you turn your bike off. I personally run my heated clothing from an unswitched circuit. That is because I always unplug it when I get off the bike so it’s not going to stay on. With an unswitched circuit you will be able to run an air compressor off your battery without starting the bike, but of course you can start the bike and run the compressor too.

Switched circuits- will turn on and off with your bike. These circuits are switched by a relay built into the Kit. These switched circuits are great for stuff you want to go off when you shut the bike off. Things like heated grips, cellphone charging, GPS, Sena communicators, etc all can run off of switched circuits with no fear of running your battery down.

All 3CS Kits are made by us, here in Japan, with the highest quality Japanese components. All components are available separately on our website for DIYers.

3CS Sealed Kits unit will fill most modest power needs on a motorcycle. If you need higher currents use our 3CS HD. Or if you need to power more things, go for our 8 circuit PC-8. The 3CS units are very flexible as to mounting. Components can be separated and stuffed into nooks and crannies. It’s really the ultimate solution for many smaller dual sport bikes that don’t have room to mount fusepanels like my PC-8.

Using our 3CS Sealed Splitters you can power more than 3 circuits. We also make and sell 3CS Sealed Leads for your installation needs. This is a highly modular system that will all plug together and is easily re-configurable.


3 Circuit Solution Sealed One Fuse Unswitched

This Kit is for medium power needs up to 35A total current on the Kit. (40 cm Kit shown, longer kits available)

This Kit has two main fuseholders. The black is for the switched circuits which also each have a separate fuseholder, the main white fuseholder is for the unswitched circuit.

Two switched outputs are provided, controlled by a 20A relay and a main fuseholder of 20A max. Switched outputs are max 12A each. These switched outputs are great for most of your accessories, cellphone, GPS etc, even heated clothing can be powered.

One unswitched output is provided direct from battery using its own fuseholder, with max capacity of 15A. The bike battery can be charged with this circuit. This higher power circuit can also power an air compressor or power heated clothing. Or you can use this circuit for a GPS which will stay on and powered when you shut off the bike.

Battery leads are 16 inches long (40cm) on the shortest version, longer kits are available. The relay is a very compact 20A unit with clear protection shrunk over it. An extra terminal and seal is included, as well as fuses and cable ties. Extra connectors and parts are available below.

Leads, extensions, and splitters to plug into the 3CS Sealed are now available. Two Positaps are included for the relay switching wire and ground.

3CS Kit Options:

FREE - Switching Lead Posi-Tap Choice: I now give you a choice of a Posi-Tap to suit different wire sizes. Some bikes, especially CanBUS bikes have very small wires. The parking light wire definitely needs a PTA2022 it’s so small. There is no charge for this option but of course you must be buying a 3CS Kit above. See the Posi Products Page for info about Posi-Taps and their sizes.

The Kit’s default is the PTA1800 which will fit most bikes but it’s nice to have the right size.

Order a few extra sizes from the Posi Products Page and make sure you have one that fits just right.

Switching Lead Posi-Tap Choice (Choose Once ONLY)

Choose


CanBUS Protective Diode Option: A protective diode can be ordered inline on the ignition switched lead, preventing reverse current flow back to the bike. This is highly recommended for CANBus bikes.

Protective  Diode in Switching Wire Option $5.95

The 3CS is hand assembled in Japan and made of the highest quality materials. All parts are made in Japan.

The 3CS can be used on any bike, even a mini bike or mobility scooter.

The 3CS is perfect for small dual sport bikes or sport bikes.

You can install two or even three of these Kits on a bike, so if you find you need more circuits in the future you can add another 3CS or use a splitter.

I have a 3CS on each of my own bikes. They are powering my GPS, an aux socket, heated clothing, and aux lights.
