Motorcycling has been a passion of mine since my student days. From that moment on, I encountered almost every possible difficulty with it. The electrical short circuit is one of them. It’s a very tiresome issue to find, but practicing the whole process several times will help you investigate correctly.
Each step requires strict attention in addition to safety. This article will give you full instructions on how to find it. As an experienced motorcyclist, I will accompany you through all of this. Let’s jump to the steps first.
9 Steps To Find An Electrical Short On A Motorcycle: Most Effective Way
Electrical shorts behave like a rat in a cave. Finding something hiding in a cave requires precise steps. Trying to find it without any effective way will waste your valuable time. In addition, it will leave you with no result. Allow me to introduce you to some productive steps to find it.
Step-1: Necessary Equipment
Equipment is the primary step of all. Without properly picking the right tools, you won’t be able to track down the electrical short you are looking for. In fact, it is impossible to find any shorts without the necessary tools. Hereunder are the tools that you need:
- Good quality multimeter;
- Circuit tester screwdriver;
- Motorcycle repairing tools;
- Allen keys;
- Wrench;
- Electrical tape.
Step-2: Separate All The Body Parts Of The Motorcycle
Before proceeding to locate the electrical short, you must isolate the body panels including the headlights, taillights, gauges, kits, and any other additional body panels. Starting with the headlight, gently pull it out of position and disconnect all wiring connections.
Apply the same method to the other parts as well. Remove the fuel tank and if you have a sportbike, make sure you remove all the kits. It is also necessary to remove the seat as there is a lot to examine underneath.
After all visible body panels have been removed, the next step is to remove the interior brackets. Many mounts inside the motorcycle also need to be separated. So make sure your motorcycle is completely naked.
Keep in mind you have to have your motorcycle only with its frame and wires, otherwise, you cannot proceed further. It will be risky for your motorcycle including you.
Step-3: Check The Headlight Wiring
Headlight wiring is one of the most prone electrical short areas of a motorcycle. That is why it needs to be examined giving proper attention to detail. Using the multimeter, you are going to step to find the electrical short you are looking for.
By isolating the headlight from its location you will see many different wires hanging out the back. Don’t get confused with this. First, set the multimeter to continuity mode, which is ohms mode.
If you then connect the black and red terminals, you will get a near-zero reading.
Allow the end of the black and red wires of the multimeter to get connected with the two ends of the wires of the headlight housing.
The connection doesn’t have to be with any specific wires. If you get a reading coles to zero again, you can consider that there is continuity in the wires.
The number close to zero ensures that the wires are okay and no electrical short is going on in that circuit. After finishing the task, cover the wires with electrical tape as there will be no chance of getting any extra shorts.
Step-4: Test The Wiring Of The Battery Section
Typically the battery has a positive and negative end. Check your battery’s health. First of all, check if it is supplying the desired output. Right after that, connect the wires with the multimeter. Observe it multiple times. Make sure the area is clean during the process.
Assure all the metal consisting parts are smooth. It cannot make the flow of electrons in the correct order if it is corroded. This is how you will get the reading of the battery section. Plus, do check the other wires related to it.
The battery compartment of the motorcycle is one of the difficult problems when it comes to wiring. Thus you have to take every step very patiently. Finding the electrical short cannot be achieved on the first try, you have to check it multiple times because its wiring is a little bit complex.
Step-5: Inspect The Main Fuse
The main fuse is generally located in the middle of every motorcycle. Check the main fuse also with the help of a multimeter. Attach both ends of the terminal to the wires of the fuse.
Look for any uncertainty in the reading meter. If you notice any glitch or the number is far away from zero, you should know that this is an issue to take care of. Enable the multimeter on ohms mode and check it again.
No sign of continuity means it has an electrical short which needs to be fixed. It is important to know that the main fuse is the mother of the entire circuit of your motorcycle. Since it is one of the vital electrical wirings, the significance is huge for other electrical wirings.
Step-6: Ensure The Connectors Are Corrosion Free
All the connectors that are present in your motorcycle have to be smooth with no rust. Rust will block the flow of current in many cases. It is seen that people couldn’t find any electrical short even after examining the whole electrical wiring of the motorcycle. You can easily make a pass without noticing your corroded connector.
This connector can typically drive into many shorts. Besides all of that, a corrosion-free connector can carry the process smoothly. As a result, make it corrosion free if it is noticed.
Step-7: Examine All The Ground Wires
The wires that are connected to make a safe completion of an electrical circuit are typically known as the ground wires. These wires protect all the main electrical joints to prevent any damage. That is why you should check your ground wires if they are accurately connected or not.
Any kind of breach of the grounded wires can cause a short in the wiring. Check the wire’s resistance correctly with the help of the multimeter. The light bulb technique is one of the popular ways to do it. Also, you can check it with the continuity mode too.
Step-8: Verify The CDI Coil Wiring
Capacitor-Discharge Ignition, known as CDI works so as not to misfire the engine of your motorcycle. The motorcycle’s engine needs a spark which is developed with the help of a CDI coil. This coil eliminates the misfiring that is not acceptable for your engine.
The wiring of the CDI coil must be verified correctly. Many electrical shorts are seen with the misfiring issue. Because of its poor wiring, it can easily cause an electrical short which needs to be inspected by the multimeter.
The use of multimeters is substantial in this sector. You should be aware of all the units and do not leave until the unit is completely checked.
You might get a little confused at the wiring of it but it’s easy to do. Make sure you are working with the wires only. Avoid touching other electrical brackets. However, check if there is any type of odd management of wires.
Step-9: Plug Each Wire Correctly
After you have ensured all the wiring is properly, now it’s time to ensure all the plugs of your motorcycle. Besides the wiring, a lot really depends on the plugs in the motorcycle. Lose plug connections can increase the tendency of electrical shorts.
The multimeter will give you a reading of the continuity of it, but the correction of plugs cannot be determined with it. Inspect the entire motorcycle. Check every plug attentively. Remember, anything that gets avoided can cause problems in the future.
These are all the steps you need to follow to find an electrical short in your motorcycle. Nonetheless, you can proceed with the steps randomly, but you have to maintain the guidelines.
