Thunderbird 900 Ignition Failure

Mine is dead too. Yesterday I went hard over a few bad bumps on the road that I did not see. The engine gave away and has the same issue. The click sound and no fuel bar etc. The lights do come on.
So I took it to a garage and the mechanic said the battery is conked out. So I put a new battery in yesterday and got it charged at the garage and then took it home.
Today I tried to start with the new battery and the same thing is happening. I paid a lot of money to get the bike from where I had stopped to get it to the garage and now have to pay the same thing to get it back to them.
Any idea why this is happening even with a new battery.
The mechanic said it does show low voltage so could it be something else then went when I went over the bumps?
Any help would be much appreciated.
Thank you.
