Do coil wires go bad?
If the engine stops and starts erratically while driving, or if it cuts out altogether and refuses to restart, you may have a bad wire between the coil and the distributor. Constant movement, caused by engines vibration and the wire’s tendency to flex slightly, fatigues the wire’s central core.
Where does the CDI wire come from on a bike?
Both directly run to the CDI (using the original cable and plug). : and a red/black, which also comes from the engine block. A note to make here: The core red/black seems to be silvercoloured instead of cuppercolored wire, while the one from the CDI is a cupercolored cable.
What kind of wire do I need for a kick start bike?
It is a kick-start bike, and I want to use it without a battery and just connect the required wires only, stripping everything else. – green-ish or blue-ish wire (Connected to other ground wires, but what else should I connect it to. To the frame or something else??) – white/black (kill-switch wire.
How do you plug in an ignition coil on a motorcycle?
We suggest using a standard relay pigtail which plugs onto the relay and has 5 wires coming off it that correspond to the connectors on the relay. Connect the relay to the motorcycle and then solder wires to the pigtail. Once all connections to the pigtail are complete, plug the pigtail onto the relay.
Which is the best way to wire a motorcycle?
The easiest way to wire a bike is to have all your connections in one place. This means you won’t have excess wires running up and down the bike with extra joins everywhere. Then if you do have any problems you only have one place to look.
How does electronic timing work on a motorcycle?
Electronic timing has simplified how to troubleshoot a backfiring problem because there are less parts to check off as the culprit. The way electronic timing works is by sending a voltage signal to your ignition coil when one of the cylinders is in its compression stroke and about ready to fire.
What kind of wire do you use on a motorcycle?
Connect the Red wire from the reg/rec to the positive (+) battery terminal and the green wire to the negative (-) terminal. Some bikes, like CB750s, will have an additional white field coil wire bundled with the yellow stator wires.
Where does the spark plug go on a motorcycle?
Your coils should have two small input wires (in most cases). Attach one from each (if you have more than one coil) to the backbone wire. The remaining wire connects to your points or chosen electronic ignition. The thick wire with the cap goes to the spark plug—but you already know that, right?
What causes arcing in electrical wire on motorcycle?
A breakdown in the insulation can cause arcing in the plug wire. You will be able to see the wire spark in low light conditions. Plug caps may be cracked, which can cause corrosion or an open circuit. To test the cap, you will need to remove it. Use your multimeter to check for resistance. It should read in the thousands for Ohms.
