So you jump started it and connected to the battery in reverse polarity? You mentioned that right at the end as an afterthought, but that is the thing that did it in! It is no good taking it to a normal mechanic workshop, you need a motorcycle or car auto electrician. These things are fixed with 5 grand scan tool computers and oscilloscopes and people that can read wiring diagrams and analyze computer operated functions!
Take it to an auto electrician. My guess is the ECU is ruined. You need proper diagnostics by someone with experience of vehicles affected by reversed polarity. The alternator also needs testing.
you may have blown all of the modules on the vehicle whats does it do now? most vehicle electronics have reverse polarity protection but without the answer that whats its doing now i cant help the alternator will be the 1st thing to be blown
With battery disconnected, take a meter reading [resistance / ohms] across the battery leads. It sounds like you have close to a short circuit in your primary charging/supply circuit. 0.6 ohm will take out a 20 amp fuse. Ohms law I = V/R. Quite a few other factors to take into account but you'll have to find what's causing the low resistance.
Looks like you may have incorrectly jump started your bike. If you have, then possible major damage - ECU - regulator - stator - the list could be endless. People often put + to - and this means reverse polarity. Same as putting you battery in backwards. Bang.
Hi, well the reason this has happened is that these contacts are stored in battery backed up NVRAM, now this RAM is very sensitive to polarity reversal, and also due to the way it works, doesn't have polarity reversal protection, on that circuit. So when you reversed those batteries even though the reverse polarity protection saved the Unit as a whole, the NVRAM would have been destroyed or wiped at best. These is no real way of replacing this NVRAM, I guess you could send it back to the factory though and ask for a "Quote" with view to the repair.
if you are lucky, only the fusible link(in the fusebox in the engine bay) is blown. if you are not lucky, a whole lot of modules are blown, and this is really expensive.
