the fuse has blown 30A Battery

[AntonD]

Hello everyone!
Today I was riding on the highway and the motorcycle first lost power and immediately stalled.
The dashboard went out and it stopped showing signs of life, did not respond to the key. I opened the fuse cover and saw that the battery fuse had melted but did not burn out.
I have a NOKO lithium battery. When the motorcycle was brought to my home, I changed the fuse to 10A (I took it from the horn), changed the battery to a spare one and it turned on, but when I tried to start it, the fuse immediately burned out (the starter could only turn a couple of times).

Tell me where to look for the problem? The charging relay? I changed the connector on the charging relay about 4 months ago and since then there have been no problems

Firstly - a 10A fuse in a 30A spot has a very short lifetime.

Secondly - I'd look for a shorted 'plus' cable. Visually inspect it to see if it may have rubbed through and is contacting the chassis. It probably wouldn't hurt to have the electrical diagram handy.

There is a possibility the fuse got a little loose or corroded in the holder and overheated.

DO NOT put a higher capacity fuse in the 30A spot!

The fuse melting is a result. You need to find the cause.

Might be the lithium battery. They have internal circuit protection and will go into protect mode. Just a thought
