I have a 2017 F3 800. Bought it last year in September. Less than 1500 miles I had to replace the ECU. That was a few weeks ago. Now, I was riding for 2 hours and then I got gas and started up and then shut right down. Tried to start it again and when I turned the key, nothing happened. Now lights or anything. Got it home used the quick charge and it wouldn't charge. Hooked the leads up to the battery terminals and it says charging and than shorty after it said charged. Tried to turn it on again and nothing happened. Any suggestions?
