Fuse radiator fan was blown

[RodeoDude]

My bro has a G310R too, and last week it was throwing a tantrum lol.
The engine ran hot, like more than 250°F, when the red warning light up.

Then the orange engine light up
He checked and found out that the 7.5 amps fuse was blown and didn't stop melting
He tried to directly current the fan, and it works
Now, the bike has been at the dealership for almost three days
I wonder if this case happens a lot? Anyone else ever experienced it?

A blown 7.5amp fuse for the radiator fan could point to an electrical overload or a short circuit in the wiring. Did your brother check for damaged wires or connectors near the fan? It also helps to inspect the relay. Faulty ones could cause repeated fuse failures.

It's not very common, but it could be a wiring or fan circuit issue. Hopefully, the dealership gets to the root cause, feel free to let us know what they say

I would add a fauly control module or a relay into the mix

Doesn't happen a lot based on what I know. Sounds like an electrical issue you need to get fixed immediately or else.

if your bro's bike is still at dealership, i hope he had his coolant system checked too! that could be causing the issue or the next one to act up!

I've noticed that a few times with the G310R as well. It's usually due to a short in the fan wiring or an issue with a connector. You made a smart move by testing the fan directly. If it works, there's a good chance it's the harness or a worn wire that's blowing the 7.5A fuse. The dealer should be able to figure it out,just let them know to check for any pinched wires around the radiator shroud.

I experienced something similar with a G310R not too long ago, the bike was overheating, and the fuse kept blowing. It turned out that the problem was a short in the fan's wiring harness close to the radiator, likely due to a pinched wire. We decided to bypass the fuse, tested the fan directly, and then took care of the damaged wiring and checked the relay. It took about a day, but after that, the bike was running cool again. If you're facing this issue, I strongly recommend having a pro take a close look at the wiring and relays, those pesky electrical problems can be a hassle, but they're definitely fixable!
