Freewheeler

Hi all Newbee here...need some helpful advice from anyone with experiences of non start through electrical malfunction. Bike's alarm would not deactivate for me to start machine. Replaced alarm fob batts, no joy, new main battery, no joy. Bike is in mates garage now stripped down as I asked him to take alarm off of bike, he's tried to bypass alarm but still cannot get a spark. Any ideas please ? Thanks in advance
