I have a 2019 Mav RC 1000r motor and I swapped out the battey.Problem is, I crossed the neg/positive terminals and fried the battery. Now the gauge shows low voltage and it won't start after a 30 minute ride or so. 12 volts is the highest I has shown when I put the original battery back in. Did I fry the voltage reg. too along with my lithium battery? If so, is it a tough job for the average bonehead? Thanks.
