What is a dirt bike coil?
The ignition coil on a motorcycle serves to step up the relatively low battery voltage to the high voltage needed to fire a spark plug. Coils are generally a sealed, water-tight component. They should be tested as part of a troubleshooting procedure whenever the motorcycle becomes difficult to start or runs rough.
Are Dirt Bike coils universal?
Most coils are swappable, but not all. You need to get the shop manuals and see the expected resistance of each to be sure.
Can you use any coil on a motorcycle?
That, essentially. It’s a single coil, 12V in, big jolt out, pretty much anything generic will do the job.
How to trouble shoot your dirt bike electrical system?
As stated earlier, many times the coil wire is not touching the inner metal plug wire ring. If the coil passes a continuity check you will need to get the resistance and peak voltage values as outlined in your manual and verify that yours are correct. Another trick guys use on older bikes is to run the coil ground directly to the engine.
What do you need to know about coils on bikes?
You need those resistance values to properly check your coil. Also, when checking your coil, do it attached to the bike and make sure that it is grounding properly. As stated earlier, many times the coil wire is not touching the inner metal plug wire ring.
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.
How are the brake lights on a motorcycle wired?
Your front and rear brake light switches each have two wires. Attach one wire to the backbone wire and the other one to the third wire on your taillight (brake light wire). 7. 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.
