Hey there, fellow motorcycle enthusiasts! I'm an Ignition Coil JH70 supplier, and I know how frustrating it can be when your ignition coil acts up. One common issue that might pop up is a blown fuse related to the Ignition Coil JH70. In this blog, I'll walk you through the process of replacing that pesky fuse, so you can get your bike back on the road in no time.
Why Fuses Blow in the First Place
Before we dive into the replacement process, it's important to understand why fuses blow. Fuses are like the guardians of your electrical system. They're designed to break the circuit when there's an overload or a short circuit. When too much current flows through the ignition coil circuit, the fuse heats up and melts, cutting off the electricity to prevent damage to the coil and other components.
Common reasons for a blown fuse in the Ignition Coil JH70 circuit include:
- Short Circuits: A short circuit can occur when the insulation on the wiring is damaged, causing the wires to touch each other. This creates a direct path for the current, bypassing the normal resistance in the circuit and causing a surge of electricity.
- Overloading: If you've added aftermarket accessories that draw too much power, like a high - intensity headlight or a powerful audio system, it can overload the ignition coil circuit and blow the fuse.
- Faulty Ignition Coil: A malfunctioning ignition coil can draw excessive current, leading to a blown fuse.
Tools You'll Need
To replace the fuse related to the Ignition Coil JH70, you'll need a few basic tools:
- Fuse Puller: This is a small tool designed to safely remove fuses from the fuse box. If you don't have a fuse puller, you can use a pair of needle - nose pliers, but be careful not to damage the fuse.
- Replacement Fuse: Make sure you have the correct type and rating of fuse. You can find this information in your motorcycle's owner's manual. For the Ignition Coil JH70, it's usually a small, blade - type fuse.
- Multimeter (Optional): A multimeter can be used to test the fuse and the ignition coil circuit for continuity and voltage. It's not essential, but it can be helpful in diagnosing other potential issues.
Step - by - Step Guide to Replacing the Fuse
Step 1: Locate the Fuse Box
The first step is to find the fuse box on your motorcycle. In most cases, it's located under the seat or near the battery. Refer to your owner's manual if you're having trouble finding it. Once you've located the fuse box, open the cover.
Step 2: Identify the Ignition Coil Fuse
The fuses in the fuse box are usually labeled. Look for the fuse that's related to the ignition coil. It might be labeled "Ignition," "Coil," or something similar. If the labels are worn off or unclear, you can use the multimeter to test each fuse to find the one that controls the ignition coil circuit.
Step 3: Remove the Blown Fuse
Use the fuse puller or needle - nose pliers to gently pull the blown fuse out of the fuse box. Be careful not to break the fuse or damage the terminals in the fuse box.
Step 4: Inspect the Fuse
Take a look at the blown fuse. You'll notice that the metal strip inside has melted. This indicates that the fuse has done its job and protected the circuit from damage.
Step 5: Install the New Fuse
Take the new fuse and make sure it has the same rating as the blown one. Carefully insert the new fuse into the fuse box, making sure it's properly seated in the terminals.
Step 6: Test the Ignition Coil
Once you've installed the new fuse, close the fuse box cover and start your motorcycle. If the ignition coil is working properly, the engine should start without any issues. If the engine still doesn't start or the new fuse blows again, there might be a more serious problem, like a short circuit or a faulty ignition coil.

Troubleshooting Tips
- If the New Fuse Blows Immediately: This is a sign of a serious problem, like a short circuit. Check the wiring for any visible damage, such as frayed insulation or exposed wires. You may need to use a multimeter to trace the circuit and find the source of the short.
- If the Engine Still Doesn't Start After Replacing the Fuse: The ignition coil itself might be faulty. You can test the ignition coil using a multimeter to check for continuity and resistance. If the readings are outside the normal range, the ignition coil needs to be replaced.
