If you've confirmed you've got ground coming out of the ignition you'll have to check if you've got it going into the alarm and if you've got continuity between the alarm and the ignitor. I've never had an alarm on a bike so I've no experience of them but I think all they do to immobilise the bike is they stop the switched ground getting to the ignitor so that stops spark and they stop the switched ground between the starter button and the cut-off relay so that stops the starter motor turning over. Your starter is turning over when you press the start button so that part of the alarm is working so that might point more towards the alarm is actually working but there's a break in a wire. But I guess it's possible that something has failed in the alarm that only affects the ground to the ignitor and not the ground between the starter button and the cut-off relay
