What's wrong?
When I installed a grip heater and various other useful electrical accessories, the engine wouldn't start.
That's probably a blown fuse due to too many electrical accessories.
Fuse? What’s that?
A fuse is a safety device to protect the electrical system of a motorcycle. By melting itself, the fuse interrupts the circuit and prevents damage to the electrical system.
In the event of an electric current, the fuse blows, which serves to prevent the wiring from burning out or starting a fire.
I see, so the fuse protects the motorcycle from problems like that.
Motorcycles mainly use these two types of fuses.
A blown fuse is often caused by:
(1) Overload due to excess amperage from electrical accessories
(2) Reversed connection of battery terminals
(3) Wiring short circuit (contact with frame or other components due to
wiring wear, etc.)
(4) Regulator malfunction (overcurrent due to voltage instability)
Of these, your problem today is a blown fuse due to (1) and (2).
Now, let me tell you about how to replace a fuse.
1.Causes of Blown Fuses
The first one is overload caused by excessive use of electrical accessories, which you have experienced.
Fuses have a specified current capacity they can handle. If that capacity is exceeded, the fuse melts and breaks the circuit to protect other electrical components like the meter and the motorcycle itself.
After replacing the fuse with a spare fuse, make sure that the total amperage of electrical accessories does not exceed the specified value before starting the engine.
Do not forget to restock your spare fuses when you use them!
Then, the second cause is when the battery's terminals, + (positive) and - (negative), are connected in the reverse order.
Seems like an easy mistake to make.
But if you do, the main fuse, the 30A-40A fuse, will blow. If it does, immediately disconnect the battery terminals and replace the fuse. If the engine does not start even after replacing the fuse and connecting the battery terminals correctly, the ECU or regulator may be damaged, so have it checked at a store.
When attaching to the battery terminals, start with the positive.
When detaching, don't forget to detach the negative terminal first.
2.How to Replace a Fuse
Next, I’ll tell you about how to replace a fuse.
Okay, how should I do that?
As stated in the owner's manual, your motorcycle comes equipped with a fuse puller tool. So, start by using this tool to remove the blown fuse.
Fuse and fuse puller mounting locations vary by model; refer to the owner's manual for more information.
Identify the fuse that blew before replacement.
Open the fuse box. The fuse that looks blown like the one shown in the
following illustration is the one that needs to be replaced.
The fuse puller is like a pair of tweezers. Use the puller to remove the fuse by pinching the head of the fuse.
Although you can use your bare hands to remove a fuse, be careful to do these things first:
If you follow these precautions, you'll be just fine in the event of a blown fuse.
