Hello all,

Firstly, sorry for my bad English.

My ADV has problem with this motorbike after I connected reverse polarity battery with exist low battery (not enough to open the indicator switch). Actually, no thing happen after I connect, only the fan in the head was running. After that, I found something wrong and removed the connection
The exist battery is about 6.5v after that. No fuse in fuse box is blowed.

And then, I connected the right way, the indicator switch can turn on, but no power exist except indicator led bar, no horn, no signal, no LCD, no light.
After that, I lookup up for the solution on Internet, I removed all fuse, re-connected one by one and found that.
* When keep the switch in ON side and remove the BACKUP FUSE, the indicator switch is turned off, the power is on (except Starting Engine).
* When keeping the situation above and re-connect BACKUP FUSE, the little spark appear and nothing else.
* The BACKUP FUSE slot have been connected to GROUND.

Can you help me, or let me know if anything is damaged, to let me prepare the worst situation.

My country is blocked down due to COVID-19, none of garage is opened until end of Sep.

Thank you very much.
