Hi, I ask some suggestion because my Baghira has a problem that is driving me crazy.
A coupole of months ago I washed the bike, because was too dirt of mud and salt. When I coma back home i heard the relay "buzzing", so I thought some water entered in some plugs or so on.
After a couple of days, when well dry. Nothing more.
Then a week later started again, even if no rain or water for days. I replaced the relay (that was more than 10 years old) and everythign ok.

Today, coming back home in the rain, when i stopped in the garage.. I head again the noise.

So, do I risk to "burn" something when the relay buzzes? I don't know how many km i drove inthis condition, but no more than 10.

Do you have any idea? Maybe is not connected, maybe is a sign. The neutral light stopped working for weekes, after some days was not working continuously. I thought was burnt, but still haven't had any time to replace. The side stand switch works,because if I release it with the gear inserted the engine stops.
TOday.. the neutral switch started working again. Could it be the switch defected, or maybe the water enters?
Thanks a lot!!!

really weird stuff can be from a bad ground or some thing shorted to ground thats not supposed to be grounded

really nasty crud in the starter button on the handle bar

is a place to start

Thanks David.
For sure i will start following the "power on cables", even if the first time happened on the handlebard were mounted the "covers" to protect my hands from the cold (i come back from the mountains, it was -5°) so I think that there were no water inside the right block.

Last year I had another electrical problem: even withthout the keys inside the lock the light were on!!! When i took away an usb power unit - defective - that was connected directly to the battery the problem disappeared. So I thought it was that usb stuf that was spreadin electric energy inside the system. And few times the rear buld socket were oxydized and the light switched on when I pressed the front brake.... So, somethign strange sometimes happens.
I red in the forum that the electricval system of our motorbikes is not so "strong", and I think I can confirm. I will be patient, and disassemble as much as I can to find any samll defect: i know could be a long hunt.

Thanks, i will keep you updated!

Hi all, a little uodate.
This weekend I had some spare time, so I tried to understand something more.
I started soaking the side stand switch. When I rotated the key.. "brrrrrrrr", the relay started buzzing. So i disconnected the cable, under the tank, to see if it continue buzzing. It didn't. "Bingo, I found the problem".
_When I plugged again the switch.. the relay still didn't buzz.
So, I soaked other parts with electrical devices, and still didn't do any noise! I really can not undestand. The power on switch and cable are ok, I opened it.

I just don't know how to reach the neutral switch, I had a look on the left side, close to the gear shaft, but I didn't see any wire, excepted the one entering inside the carted close to the generator, and another little earthing cable just under the left carter. Do you have any suggestion how to check this?
Thanks!
