I have a Suzuki DRZ 400S motorcycle that has electric start, When I push the start button the nothing happens. I installed a new battery and thought that was it, nothing again, I started to jiggle wire and move things around and nothing. I tried it again and it started, I'm guessing i have a corroded connection or some loose or dirty connection. Any thoughts on how to trouble shoot this? Maybe by eliminating safety switches or something. thanks.
