Brutale S 750 Batterie issue

Hi Guys,

today I wanted to install the battey in my Brutale and have connect it wrong for the short time maybe 15 seconds, as soon as I have realised it I unpluged it... Then I installed it right and started the engine... It works and runs ok, all the electrical features are funcional, but the batterie light is always on. I also made the test, to unplug the batterie but the engine died. So I think the alternator got something... I would appreciate any suggestions and help.

Thank you all in advance.

Best regards,

Ziga

I have seen that the 40A - 32V Fuse was damaged, so I changed it and it's working for now I hope. 😊 But if someone has a suggestion what to check, please tell.

And another one does it.
If it's going okay now, then it should be okay mate.

Hahaha, you're probably not last one either. You where probably lucky that you didn't start the bike before noticing your mistake.

Maybe I would have, tu as soon as I wanted to put on the circle, the Fan started running from it self, so I realized it, somethings wrong... 😊 But it seems that the Fuse saved further damage... (I hope so)...
Donsy what about the alternator test, can I test it like that: starting the engine and then unplug the battery, as I know the bike should then run buy itself, if I'm not wrong? Thanks for your support. 😊😉

Technically it might be possible for the bike to run just from the power generated by the battery, but physically it's not that easy because you can't just remove the wires from the battery as the battery is part of the circuit.
The way to test the alternator is with a Multimeter across the battery terminals as described in the fault finding part of the manual.
If the alternator is faulty, the battery light usually lights up on the dash.

you blew a fuses no big deal ! doubt there is any other damage if all else is working.

do not disconnect the battrey while the bike is running! you need a volt to make an amp! the alternator can't make amperage wihtout the battrey. if you have around 14.5 volts while the bike is running around 2000 rpm your ok. check the manual for actual rpm vs output voltage.

also always disconnect the negative termanal first and install last when working on the battrey. this way if your wrench touches the frame you wouldn't short to it.

the bike will run fine with just the battrey as long as it has enough power
