Hi,

I want to upgrade the motorbike from 6V so i bought a 12V battery


and a 12V engine


but the problem is when I isntalled them It runs some meters and then turn it off.

We have a fuse between the battery and the circuit:

But I've tried wihout the fuse and I burned one engine.

I tried with one standard 10A car fuse and break it as soon as I powered on the motorbike.

This is the relay we have:

So what is the fuse I have to put it between them?

Thank you in advance.

If that relay is rated at 6v then it will burn up running at 12v. You would need to match a relay for the voltage you are running at.
6v rides are usually protected at around 20amps when stock . I would not go any higher than a 30amp fuse with stock wiring. After installing your new fuse, monitor the wiring temperatures to ensure they aren't getting too hot. Whenever you alter a ride on there are hazards involved. Do not over build the vehicle and risk harming your child. Safety first.
